Beam-steered Nd:YAG (Neodymium:Yttrium Aluminum Garnet) laser marking provides a unique combination of speed, permanence, and imaging versatility in a noncontact marking process. Laser marking can generate considerable savings in reduced manufacturing and tooling costs; elimination of secondary processes and consumable disposal; and reduced inventory expense, quality-control costs, and maintenance downtime. Laser marking frequently improves the aesthetic appearance of the marking image, thereby increasing the product's perceived value.

Of all materials, plastics are the most challenging in terms of the laser's interaction with the material and the required image quality. The wide variety of material chemistries and colors and the aesthetic requirements of most plastics applications require special consideration in both material chemistry and imaging techniques. The successful implementation of laser marking technology requires a working knowledge of the laser marker's function and capabilities and a committed, team approach by the user.

Marking Fundamentals

Laser marking is a thermal process that employs a high-intensity beam of focused laser light to create a contrasting mark on the material surface. As the target material absorbs the laser light, the surface temperature increases to induce a color change in the material and/or vaporization of material to engrave the surface.

Beam-steered laser marking employs mirrors mounted on high-speed, computer-controlled galvanometers to direct the laser beam across the target surface. Each galvanometer provides one axis of beam motion in the marking field. A multi-element, flat-field lens assembly subsequently focuses the laser light to achieve high power density on the work surface while maintaining the focused-spot travel on a flat plane. The laser output is gated to blank the beam between marking strokes.

Marking can be accomplished at speeds of up to 5000 mm/sec with positioning speeds between marking strokes of 50,000 mm/sec. Because the process relies on heat conduction into the plastic, marking speeds are usually slower than the system's maximum capability to allow sufficient conduction to achieve the desired results.

The beam-steered marker can duplicate virtually any black-and-white image, including variable line widths and images as small as 0.0001 inch. Present computer-imaging technology produces highly intricate graphics with line widths, resolution, and accuracy well below 0.001 inch. Because the image is created by "drawing" with the laser beam, the marking time is dependent on the amount and complexity of the text and graphics. With computer-generated imaging, any graphic element or the entire marking program can be instantly changed before a new part is positioned for marking.

Nd:YAG lasers amplify light of 1.06mm wavelength in the near-infrared. They are unique among the different types of lasers in that they operate much like an "optical capacitor." In pulsed operation, the Nd:YAG laser stores energy between pulses, resulting in peak powers of kilowatts of light energy. A Nd:YAG laser emitting 75 watts of continuous light, pulsed at 1 kHz, emits a train of pulses with peak powers of 110,000 watts. The "optical capacitor" effect provides the peak power necessary to vaporize material. For plastics applications, the laser must also be run in a "top hat" mode, where the power distribution is fairly even across the cross section of the laser beam in order to eliminate "hot spots" in the marking path.

The beam-steered Nd:YAG marker frequently replaces acid and electro-etch systems, stamping and punching systems, and those other marking systems that permanently mark products by imprinting or engraving. It also replaces other, less permanent printing systems, including ink jet.

Uncoated Plastics

Most uncoated plastics must be doped with a material reflective to the laser wavelength to prevent over-absorption of the laser light, which results in loss of control of the temperature rise and excessive melting on the surface. Light-colored plastics are doped with mica, titanium dioxide or carbon-containing materials. The heat generated by absorption of the laser light causes the carbon to migrate to the surface, producing a contrasting dark mark against the unaltered background plastic.

Plastics are semitransparent to the near-infrared wavelength of the Nd:YAG laser. Depending on the degree of transparency and the laser output power, the laser beam can alter the material surface to depths of more than 0.025 mm without achieving vaporization temperature on the surface. If material vaporization occurs, the layer of carbon is thinned and the marking image will appear washed out.

There has been considerable success in altering the depth of carbon migration to create gray-scale graphics on light plastics. Adjusting the power and/or pulse rate of the laser controls the depth of penetration and therebv the darkness of the mark. Increasing the laser power will increase the overall depth of penetration and thickness of the carbon layer. Increasing the pulse rate will result in a longer pulse width and lower peak power. The longer exposure also increases the depth of penetration and associated carbon layer.

Dark plastic is doped with a material that produces a lighter color as the material expands and the density decreases. As the temperature of the plastic increases, the plastic expands to form a "blister" on the surface and a lighter-colored mark. As with light plastics, the temperature must be tightly controlled to avoid over absorption. If the temperature rises too high and the blister bursts, material is lost and the mark will lose contrast.

Not all plastics require dopant to achieve a contrasting mark. Several plastics do yield excellent results without additives; for example, most black polycarbonates produce a snow-white mark without altering the chemistry.

Coated Plastics

Coated plastics consist of a solid, translucent, or transparent plastic with one or more coats of ink or paint. The marking image is created by achieving vaporization temperature on the surface to remove the top coat and expose the underlying plastic or second coat.

Coated plastics allow a great deal of control over color selection and marking contrast. Transparent plastics allow the designer to use an underlying part to establish the background color (marking image) while the top coat determines the foreground color. Solid plastics establish their own background with the color of the plastic. Translucent plastics are frequently used for back-lit applications. The plastic is initially coated with a white paint and overlaid with a dark top coat. The laser removes the top coat, exposing the white paint for daytime visibility. When the part is back-lit at night, the lighting illuminates the translucent plastic from behind and the marking image appears in the color of the plastic.

The paint or ink used must be conducive to laser processing. Standard paints and inks are neither predictable nor controllable when exposed to the laser output. The inks burn easily and can mix with the underlying plastic while in the molten liquid state. Laser-compatible inks are mixed with a silicone-based material reflective to the laser output, thereby reducing the ink's light absorption and rate of thermal reaction. Paints must be suitable for high-temperature processing and be free of any contaminants that may absorb the laser wavelength and speed up the thermal rise.

To achieve a quality image, the top coat must be completely removed with minimal impact on the underlying plastic or secondary coat. To maximize the ratio of light absorption between the two layers, the top coat must always be a dark color and the contrasting underlying layer must be a light color. The dark color will absorb a comparatively higher percentage of the laser light, resulting in a higher surface temperature, while the light color reflects a higher percentage and minimizes the temperature rise. The underlying plastic, paint, or ink should also be thick enough to tolerate a minor amount of material removal during marking.

Marking coated plastics is a multi-step process in which the first marking pass removes the majority of the top coating. The remaining residue is removed with a second, lower-power pass to minimize the effect to the underlying material. For precise edge definition, the outline of the image is marked prior to filling in the image. The outline is marked with a heavy edge pass (i.e., 50 kHz, 250 mm/sec, 2.5 watts) followed by a lower-power cleanup pass (50 kHz, 250 mm/sec,1.75 watts). The image is then filled, if desired, with a heavy fill pass (50 kHz, 650 mm/sec, 6 watts) and subsequent cleanup pass (50 kHz, 6.50 mm/sec, 4.5 watts). Care in determining the process parameters for each pass and the edge and fill beam paths will result in a crisp, high-contrast, high-quality marking image.

Preparation and Installation

Perhaps the most critical element in the successful application of laser marking is the composition of the part programs. When replacing an existing marking technology, one must allow up to six months for conversion of existing art work to part-marking computer programs. Even if the present artwork resides in AutoCAD files, time must be allotted to convert the files to optimized marking programs.

Many users start with thousands of sheets of Mylar artwork. (Mylar is a DuPont trade name.) Each Mylar film is scanned to create a bitmap image. The scanned bitmap could be directly converted to the laser marker format with good image quality, but the cycle time would be unnecessarily long, with excessive marking line overlap.

For best results, import the scanned bitmap into AutoCAD as a positional template. Create a separate marking "logo" for each alphanumeric character and graphic image, and, in AutoCAD, place each logo in position on a separate layer, using the bitmap template as a positioning guide. A library of optimized logos facilitates the creation of programs from the scanned artwork, allows nonstandard text kerning and line leading, and ensures low cycle time and high image quality. After all the logos are in place, the template layer is removed, and the final CAD file is converted to the laser marker program format.

If the art work already exists in a CAD file format, the image elements could be optimized without using a separate library of logos. Every element including repetitive elements shared between drawings must be individually optimized. It will take considerably longer to convert large quantities of files, and there is no guarantee that every clement is optimized correctly. It is far more efficient to use the original AutoCAD file as the placement template for optimized logos.

Implementation of beam-steered laser marking requires a team effort. With cooperative implementation. manufacturing can ensure product flow and integration with existing controls, the materials department ensures that plastics and coatings are appropriate for laser marking, and engineering will produce part-marking programs with low cycle times and high-quality images. Careful team planning, preparation, and execution will result in a smooth application of laser marking technology and the associated benefits in manufacturing efficiencies, quality, and product value.

Sketchup is 3D design software that is used for many different industries.

However, for the hard to visualize area of landscape design, it can provide one of the best portrayals of the 3D landscape.

Sketchup was originally owned by @Last Software, but it was bought by Google. Hmmm....I guess Google thought it was pretty good. And it is.

There is a free version and a paid version. For the average person, the free version is fine. If you want to get more intricate with such things as grading and showing different elevations, then you will want the paid version.

For residential design, you can use this program in a couple of different ways.

The first way is to design right in the program. With a click of the mouse, you can set the drawing in a perspective position. Guidelines help you make sure you are drawing correctly. You can enter actual heights and lengths of objects, such as a house. You can put in the dimensions of the house, ie., length and width. Then use something called the pull tool to extend it up to the correct height.

It is all very user friendly. Also, what is created has an artistic flair to it, which makes it a lot of fun!

You can also view different materials for landscape elements. For example, if you are drawing a patio, you can go to the Materials area and choose what you might like. There are many different materials and you can change them as you like to see the differences. Some choices are stone, pavers, brick and concrete.

A plant palette is offered also. These are fine. However, for a more sophisticated look, there are other inexpensive components you can buy to use in your design.

The second way of using Sketchup is to create a 2D drawing in such programs as AutoCad, and import it into Sketchup. In this situation, you are working from your drawing so that an exact replica of the design is created. This allows you to see what a drawing will look like when built. Changes are easily made if there is something you don't like or want to add.

Some of the components you can add to the 3D landscape design are people, cars, grills, pergolas, plants, any many, many more. These are available directly through the program or through something called Google Warehouse. They are all free.

There is a lot of flexibility with the components. You can resize or rescale them if you need to. You can also change colors of both components and materials.

By adding window components to a house, you can actually position a person inside the house. This allows you to attain a view as if you were inside looking out. What a great feature to see what your view will be like.

You can also create scenes. Scenes let you save a particular view. These scenes can also be exported into jpeg images. You can also create an animation which is a fly by or walk through of the entire design!

Any or all of these features can be used to suit your purposes. The software can be used in both simple and sophisticated ways. There are many other features available also. All in all it is a great 3D program.

What's the point to build a shed yourself?

Well, there are several points at least. First, it's cheaper. Then, it's fun. Sometimes it's faster. But that's not all. There is something a lot more important than the price, the speed and the fun. It's the fact that you can build exactly the shed you dream about instead of conforming to the designs available in your local store.

I'll go even further and tell you that you can design your shed yourself.

"But I'm not an engineer!"

So what? You won't be building a house here. It's just an outdoor shed. Of course, you need some basic knowledge how to do it - that's why I am writing this article. You also need some basic math skills, imagination and knowledge how to work with AutoCad or similar program - or at least CorelDraw or Adobe Illustrator. Your school should have taken care for the first, you are hopefully born with the second, and the third is not that hard to learn - at least on a basic level.

So how do you go about designing your shed?

First, draw the floor. It's highly recommended that you keep it straight and easy shape - that means rectangle or square. Of course some sheds have more interesting shapes, but if this is your first design, better stick to four walls.

Then draw the walls considering that they should be high enough for a person to enter the shed. That means at least two meters high or more. Try to imagine how the walls will be built over the floor and how everything will assemble together.

On the top of the shed you need a roof. Most sheds can do just fine with a flat root but if you plan to build a larger shed (type summer house), then you may want to plan a triangle roof. Here you'll need the math knowledge about triangles from the school.

Plan the windows and the door and actually place them in the drawings. The windows should be placed in the second top half of the walls unless you are designing a very high shed.

Essentially floor, walls and roof is all you need to design - it's not that hard. At this point don't worry about being extremely precise and calculating the wall thickness. Your first exercise will not be with real materials... It will be with paper!

Scale down your plan 10 or 20 times and you'll be able to cut the parts from regular sheets of paper. That's a cheap and easy way to see if there are general mistakes in your plan and if you like the design when you see it assembled. Once you are happy with the result you can continue with more complex calculations which will include the wall thickness and the way the parts join each other.

You may need to invest between $5 and $25 and buy some shed plans just so you see what they include and what specifics you might have missed.

There is a lot more to learn about designing the shed and how to build the shed after that, so consider visiting my free e-course. You'll find loads of other useful information there like for example how to move a shed.

Buildings of the future will be constructed principally of concrete and metal. Steel is a particularly valuable material for both framing and cladding walls and roofs. Houses made of steel are quick to erect and easy to insulate, are both cost effective and lend themselves to a variety of designs, and are the most earthquake-resistant. Steel's versatility is allowing architects and designers to let their imaginations take wing, and roll forming is the most efficient method for shaping steel and other metals. Sheet metal is transformed by the roll form process into studs and purlins for framing, into panels for cladding and roofing, and into insulation. Roll forming is a technique for taking coils of sheet metal and bending the material into a variety of profiles. Roll forming requires little labor, can be integrated into a system of automatic processes such as bending, perforating, and joining, and lends itself to round the clock operation. Roll forming products for the pre-engineered building presents significant challenges for manufacturers.

The metal building industry has changed dramatically in the past few years. Builders demand better quality materials, faster lead times, and more economical prices. Prepainted materials have largely replaced postpainting framing, and galvanized metal is being employed more frequently, particularly in areas near the ocean and in agricultural applications. High strength steel is being used increasingly, profile and punching specifications are becoming more exacting, and product types are becoming increasingly complex. Roll form system manufacturers have responded with machines which are easier and more flexible to operate, can manufacture a wide range of products, are faster and more productive, as well as more economical. For example, coil handling equipment now enables the manufacturer to quickly switch coils to a different gauge or material.

This is a response to the fact that jobs now require producing a complete building rather than rolling long runs of the same component. The modern roll form machine is designed to quickly switch profiles from cee to zee, from single to double slope eave struts, to different flange and web sizes, and to different material gauges, in order to fulfill one particular customer's order. For example, the Purlinmaster roll former can switch from a 4" cee purlin to a 16" zee purlin in seven seconds, simply by touching a button on the fully automated console. It is possible to produce eave struts inline with either a single or double slope configuration, which eliminates the necessity of offline bending. Modern computer technology has also made perforating an exact science. The Punch Anywhere press system, for example, can be programmed from Autocad drawing files to hydraulically punch custom hole patterns anywhere on the strip - flange or web.

The future of the building industry will be shaped in large measure by advances in the roll form process. The modern roll form system is a completely integrated and computer-directed system of material handling, processing, and finishing for greatest efficiency and cost effectiveness. Advances in roll form machine design have practically eliminated downtime caused by the necessity of switching materials and dies. Thanks to roll forming technology, the future of the building industry looks bright.

Landscape design cost is influenced by several different factors, ranging from one extreme to the other depending on the details of each project. While there are free design plans available, many homeowners opt for a professional design to ensure an outdoor space that complements and enhances the beauty of their property. There are many different options and an amazing selection of designers to choose from, but understanding the basics regarding the cost of landscape design is an essential part of planning your budget.

Determining Landscape Design Price

There are many different things that play a part in determining the actual cost of your landscape design, but there are three primary influences. Understanding these will give you a general idea of how much money you should allocate to landscape design.

1. The overall size of your property is the biggest influence on landscape design price. Most design packages are based on an average lot size, typically around 10,000 square feet, and are adjusted for smaller or larger properties.
2. The size of the area to be landscaped is also important. A complete concept design plan for your entire yard will cost much more than a planting plan for the front of your home.
3. Your landscape design cost is also determined by the features and options you desire. Many professional design services offer a variety of packages so it is easy to calculate the approximate price of your project.

Landscape Design Options

Your cost will depend greatly on the details, features, and types of landscaping you want to incorporate. Swimming pool design, hardscape plans, and other specialty landscaping will affect the cost of the design, as will lighting and drainage plans. Select a landscape design contractor that can provide you with a package that best meets the needs of you and your home.

What Does the Design Cost Include?

A typical landscape design package includes detailed plans and instructions for installing your outdoor project. The plans are usually custom drawn to suit your needs and are presented in AutoCad format. The diagram is highly detailed, with illustrations, installation notes, and more. Most packages will also include additional copies of the plan, often in black and white, for record keeping and other uses.

The cost of your landscape design will generally not include the price of materials or the cost of labor to install the design. These are included in the landscape installation cost. Locating a landscape contractor that provides both design and installation services is often a great way to save money on your total project. Examples of typical landscape design packages and their costs can be found here for further reference.

Whether you're considering a complete landscape design renovation, installing an outdoor lighting plan, or simply needing a planting plan for a flower garden with year round color, a professional design will enhance the overall beauty of your home. Understanding the basics of landscape design cost will help you set a budget.

Laser engraving got it's start in the early sixties when scientists discovered they could create a light source, focus it's energy and yet have a tool powerful enough to affect a variety of materials. If you've heard the term laser etching it's basically just another name for laser engraving. In today's engraving industry, CO2 lasers, which are named for the gasses used to create the light source, are the tools of choice.

Like many inventions of modern times, lasers came out of a laboratory. They ca be used to engrave/mark almost all materials. Sometimes laser marking is referred to as laser etching however unlike conventional etching it needs no masks or chemicals.

Marking is the most favored method when one wants permanency or aesthetics. Etching is the process of marking material without cutting all the way through using reduced power. A laser works quite well for cutting acrylic (Plexiglas), PETG, thin polycarbonates (Mylar), styrene expanded PVC (Sintra), wood, paper and fabric. Engraving of graphite is a very clean operation.

Etching makes a permanent message on an in-process or finished component. The ability to laser-cut complex profiles can totally eliminate the need for additional operations, making the cutting very economical.

Marking of glass by CO2 lasers while moving can be an excellent addition for industrial environments and applications for glass marking. And when used to mark or etch glass and quartz replace traditional methods - these include sand blasting, ink pad printing, and etching. They can also provide excellent results for marking glass and provide great reductions in operating costs and cost of supplies.

Drawings can be converted into the correct format for laser marking or directly into a variety of formats including JPEG, Adobe- Illustrator, Corel Draw and AutoCAD to name just a few. Marking services can be used for hundreds of applications from computer keyboards to special promotional gifts. Products include wedding giveaways, nametags, table nameplates, engraving of trophies, laser wood engraving, etc. Because no inks are used it's permanent and the process is environmentally-friendly.

Today the engraving can be used for most jobs that are currently being carried out by the conventional industrial engravers. Laser machines and systems are used in a variety of applications and industries including the medical device industry, aerospace, manufacturing, automotive, pharmaceutical, and electronic industry.

Finally there are no consumables so the operating costs are minimal, and the laser system, if properly exhausted, runs clean, so expensive cleanup or by-product disposal is not necessary. Today laser engraving, cutting and marking is a viable and versatile technology that is being used by many engravers to improve productivity, add more available services to their customers and increase profits.

What is Software?

Software is a set of instruction written to interface between man and machine.

Who writes this instructions?

Programmers writes this instructions.

How the programmers write the instructions /software?

They use computer languages to write software applications.

Software can be divided into three main categories:

Languages

Applications

Operating Systems (OS)

LANGUAGE:

It is one of the software type, use to write extensive applications and operating systems It did not contains any limitations in programming. By using the languages you can write any thing for a computer.

For instance just imagine a language like a piece of cloth with that you want to make a shirt or paint curtain for windows or door, than you will take that cloth to the tailor and have him made for you or if you know tailoring you can stitch it at home.

Where as: Cloth is Computer Language

Tailor is Computer programmer

Shirt/Paint is Computer application

Example of languages are:

C

C++

Fortran

Cobol

Pascal

Perl

Assembly Language

Machine Language

Java

APPLICATION:

Software applications are user friendly and most of the time it is custom made for the end-user. Because it serving a specific purpose so it is having its own limits and bounds. It will not work beyond its bounding, for example if you want design picture in a word editor you may not able to get the result according to your desire.

Following are the different categories of applications

- Database Applications

- Front End Applications

- Reports Applications

- Word Editors

- Spread Sheets Editors

- Application for presentation

- Graphics Designing Application

- CAD designing Application

- Computer Games

- SCADA Applications

Some of the popular Applications are:

Oracle

MSoffice (Word,Excel,Access,PowerPoint,Outlook, etc.)

VB

VC++

Autocad

OPERATING SYSTEM:

This is the interface between user and computer or man and machine. This is the main and mandatory software in computer. Without Operating System (OS) computer will never starts. It is the mediator between you as an user and computer.

Think that you are suppose to talk to a person who does not understand your language. What you will do in this situation? Off course you take the help of person who knows both yours and other person's language, he is the mediator. And that's what the computer Operating System is doing.

It is very interesting that the thing from which OS has comes out still require OS to run on. In other words all languages and applications require a platform which is nothing but OS. So that conclusion on any computer first should have OS than you can have language or application on it.

Example of some of the Operating Systems:

Windows

Unix

Apple Mach

Ban

VMS

RS

OS2

IRIX

AIX

HP-UX

Not all electronic documents are the same. Remember that skit from Sesame Street called "which one of these things is not like the other"? Well, engineering documents are the pink apple and they stand out from all other electronic files. CAD files cannot be properly managed by a standard document management system that handles office files, pdf's, tiff's, etc.

Companies who let their IT or "non-engineering" departments select an enterprise wide EDMS (Electronic Document Management System) often find that out the hard way. When the project implementation gets to the CAD department all hell breaks loose. CAD managers start to ask questions like: Where did my x-Refs go? Why can't I customize my drawing number and file name? You want my revision number to be 1,2,3..?

Most standard EDMS systems are designed for banking, real-estate, accounting, and similar industries which handle one version of a file that can be stored as a tiff. These files often never have to be "checked-out" or modified, just stored, copied, or distributed. Systems like these do not recognize xRef's, they don't allow you to view and mark-up CAD files, and they often exaggerate the size of your database because they use database blobs.

The majority of CAD files in existence today are DWG (AutoCAD) and DGN (Microstation). A few companies also use 3-D modeling files which require very specialized applications for file management. Usually PDM (Product Line Management) tools are required to manage 3-D files and all of their associated sub-files. PDM applications usually do not have the versatility to manage anything other than that one specific file type.

Applications that will manage DWG's, DGN's, and often associated office files include AutoEDMS, Synergis Adept, and Dv TDM. Office Document Management systems like Documentum, Laserfiche, and Filenet can only manage CAD files on a limited basis and require a 3rd party plug-in which can be very expensive.

In Summary, whatever EDMS system you choose for handling CAD files should store your electronic files in their native format, recognize xRef's, and allow you to modify simple processes like check-in, check out, document numbering, and document naming. Most CAD departments have their own nomenclature for document revision numbering and file naming. Why should you have to have a new revision created every time you check in a document? Why should you have to name your document 1, 2, 3….. Keep in mind that whatever system you are using may not be around forever so you want to make sure you can always find your files the old fashioned way just in case you have to!

In the fast paced world of plastic molding, injection mold design is one of the most interesting and challenging jobs to be found. You will draw upon all of your creative abilities as you develop the design for new products.

It might look easy because of the powerful CAD programs, but in reality, they are just tools to help you. In the field of injection mold design you often must develop new and original methods of plastic molding. This sometimes requires a lot of creativity and inventiveness. What is a typical day like for injection mold design? Most injection mold designers follow a schedule similar to the mold makers. Because their mold designs are soon going to be manufactured by the mold makers, there is a very close relationship between these two.

A mold designer spends most of his time at his computer, using powerful CAD programs such as Unigraphics, AutoCAd, SolidWorks, MasterCam and many, many others. Nowadays, the programs are incredibly fast and powerful.

Very often the mold designer will be required to communicate with the various mold makers, CNC programmers, WEDM operators, etc.. This rapport is critical for a successful career as an injection mold designer.

Usually the designer does not work quite as many hours per week as the mold maker. Often mold designers have a shop background and help out in the mold making shop as well. This is especially common if there is a slowdown in design and a lot of work in the shop. How do you become an injection mold designer? Essentially, there are two paths in the USA. One is to learn on the job and the other is to learn at a design school. Both are common and work well.

Many plastic molding designers come from a mold making background. This is especially helpful to provide a realistic approach to mold design. There is no substitute for practical experience!

Several tech schools and universities offer excellent courses on plastic injection mold design. A background in mechanics, spatial relationships, ability to visualize 3D parts, and mathematics are all essential.

Is there a future in injection mold design?

Like everything else associated with the plastics industry, the answer is yes and no. Yes, because the plastics field is growing all the time and skilled designers are in high demand and low supply.

No, because the field is so competitive on a global scale. In this electronic age the designer does not even need to be in the same country as the mold maker. I had this experience at one shop; the designer was in Canada and we were in the USA. It worked well, but required considerable phone time on the part of the project manager. Conclusion Working in injection mold design is challenging, interesting, secure, well paying and in demand. Anyone interested will find many good courses available and companies seeking qualified designers.

Training and seminars on information technology are important in any kind of business. This is primarily due to the fact that most operations and processes in business rely on computer and other technological tools. The acquisition and availability of information technology will be ineffective and senseless if the employees who are supposed to use such, do not know how.

IT training is basically composed of lectures and discussions of how to use, create, and construct information technology tools such as computer hardware, various computer software, computer programs, computer applications, and computer operating systems. This kind of training covers a wide range of topics and various forms of specializations. IT training is also categorized according to the type of IT skills being disseminated and the type of certification and qualification that will be gained.

IT Training and IT Skills

These days, there are many companies that offer IT training for businesses. Evidently, most of these trainings are provided by the manufacturers and developers of the IT tools and equipment. However, some companies composed of skilled IT professionals also provide training.

Before availing of any IT seminar or workshop, the company should first be able to assess what type of IT skills is required for the business. To add to that, the company should also be able to assess what IT skills do its employees already possess. By comparing the needed IT skills for the business and the present IT skills of the employees, the company will then be able to identify what more IT skills are necessary.

The various types of IT skills

Prior to IT training, categorization and identification of the present IT skills of the employees is necessary. Basically, the company can classify the skills of its labor force according to the kind of the know-how that each employee have which are as follows:

Application-oriented skills:

These IT skills refer to those that are used when working with application software packages. Among the most well known computer applications are the "Office applications" that allow users to create documents and presentations (i.e. MS Word, MS Excel, MS Powerpoint, MS Publisher and other basic applications).

In addition to these office applications are the more complex software that allow the user to design graphics and construct computer images and web pages such as Adobe Photoshop, Macromedia Dream weaver, Corel Draw, AutoCAD, and many more.

Development skills:

These IT skills are those that are commonly possessed by computer programmers, developers, and database administrators. These are used to construct or modify computer software, computer programs, and systems. These are the skills that are usually required for the IT personnel of the company. If an employee is equipped with development skills, he is expected to be very knowledgeable with both the hardware and the software components of computers and computer systems.

Operations skills:

These IT skills are those used to maintain the efficiency and security of computer systems and infrastructure. Such type of skills requires basic knowledge of both application-oriented and development skills. These skills are often required for computer engineers.

The field of Computer Aided Drafting (CAD) or AutoCAD is growing by leaps and bounds, and qualified designers with proper CAD training are in great demand. The right vocational school can instruct you in the use of computer software for designing, developing, and optimizing engineered designs of tools, machinery, and packaging, as well as drafting and architecture training to meet this challenge.

The use of CAD software lowers the cost of developing products and shortens design time it takes to create detailed three-dimensional models and two-dimensional drawings. Computerized layouts are developed onscreen, saved for editing, and printed out for the scrutiny of drafters, engineers, and designers.

CAD software on the market changes rapidly, making it difficult to keep up with new developments. Classifications of software vary. Two-D drafting systems, mid-range 3-D solid feature modelers, and high-end 3-D hybrid systems may be encountered by students taking CAD Training. The more powerful the software, the more there is to be learned. Each student in CAD training will work with a Windows-based computer workstation and with software for optimal CAD education.

Curriculums in CAD training programs can be broad and diverse. Students may address aeronautical drafting as well as architecture training. They will also learn about drafting, including electrical and electronics drafting, mechanical drafting, and drafting of pipelines. Additionally, students will gain experience in auxiliary drawing, dimensional drawing, and lettering. CAD schools prepare students with expertise in creating manual and computer assisted drawings in order to earn certification through exams given by the American Design Drafting Association (ADDA).

Some vocational CAD schools offer placement assistance to graduates. Professionals find work preparing technical drawings in manufacture and construction, and they are qualified to design everything from corporate towers to toys. Earnings can vary widely, ranging from $30,000 to $60,000 annually.

Computer-Aided Design or CAD meets the design requirements of speedy revisions and accurate geometry, making the process of designing very easy. CAD was first used to design and manufacture aeroplanes and now has been developed to suit the needs of any kind of designers in any field of design and have user-friendly interfaces.

Types of CAD Software:
Software developers have benefited immensely by developing various CAD software. Various CAD software offer two-dimensional designs, as well as those offer three-dimensional designs. CAD has made it possible for two people in two remote corners of the world to design and create new products using CAD software as well as the Internet. Artists, mechanical, electronics and civil engineers, architects and interior decorators use CAD software to aid in their designing process.

Designers have two kinds of CAD software to choose, either use the existing 2-D CAD software or go for more advanced 3-D CAD software. Some applications are inherently 2-D based. AutoCAD, Cadkey, CADDS 5, Medusa, and CATIA v4 are examples of 2D CAD software.

Pro/Engineer, Unigraphics NX, SolidWorks, Solid Edge, Autodesk Inventor, CoCreate Solid Designer, and VX CAD are popular 3D CAD software.

3D views are not very clear and are hard to visualize in 2D based CAD software. Hence, designers some times used a physical scaled down model of the product to make corrections and changes if necessary. This is not the case in 3D CAD software where a clear view of the product can be got aiding and quickening the design process. Making changes and corrections using 3D CAD software is easy as the design is automatically corrected, where as in 2D software the drawing may have to be recreated after changing or making corrections. 3D CAD software make it easier to identify mistakes, inaccuracy in dimensions, interferences etc. Hence, save time, energy and money. 3D CAD software designed products are reliable, fit and well designed. The time taken to design and finalize designs is significantly reduced when companies use 3D CAD software. Some software such as SolidWorks collaboration edition, 3D TeamWorks, is designed to help multiple people in different locations to work on one design using secure connections. Only a web browser and an internet connection is necessary making it possible to review designs and finalize them in real time.

It is essential for companies to analyze if they really need to upgrade to 3D CAD software, as they can be a costly and time-consuming process. While companies choose to upgrade to 3D CAD software it is essential to train personnel or hire new qualified and experienced personnel as it may take time to train existing personnel. However, it has to be acknowledged that designing industry has been helped immensely by using CAD software.
