The Automatica Tecnologia CNC Plasma Cutting Table is displayed in operation by cutting a steel plate, showing details of the THC (height sensor controller) and a fast foward 10 times the normal speed video.

We cut a metal sheet through intense laser beams to generate different shape or to fulfill different functions. The total procedure is done through a machine termed as CNC laser Cutting Machine, which runs on a CNC method in CNC machine shop. CNC is computer numerical control and most of the manufacturing machines run on this technology. CNC has brought a revolution in the industry through this application as various machines are based on this method.

In laser cutting procedure, a beam of high density light energy is focused through a tiny hole of nozzle and when this laser beam strikes the surface of work piece, the material of the work piece is vaporized.? CNC laser cutting process has become popular in the industry, owing to its capability of cutting simple to intricate designs accurately. This is the reason why it is used widely for many applications like architectural, aerospace, electronic, medical, automotive, power generation, biomedical, decorative, petrochemical and so on. Several products that are manufactured through plasma cutting procedure includes brackets, gaskets, cams and assorted mechanisms. The website www.emachineshop.com offers the best comprehensive details regarding the CNC laser cutting machine.

Laser cutting offer low cost for prototypes as physical tooling is not required. The heat distortion is very less and is restricted to 10% of material. This proves much effective in comparison to other sheet cutting procedure available in the market. The advantages provided by laser cutting include less of burrs, maintaining close tolerance, and can be performed on large range of materials. Laser cutting procedure works best on materials like stainless steel, carbon, nylon, wood, plywood, aluminum, polythene, derlin, acrylic and galvanized steel. It is difficult to cut metals like aluminium and copper alloys as they reflect laser light as well as absorb and conduct heat. . Unlike other sheet cutter technique, a software programming is also required to run the laser cutting machine and along with it operator check service needs to install to protect from error.

The material produced possesses a smooth edge and edge quality is usually very good for thin materials – around 1/16″ or less.? This procedure has helped the manufacturing sector immensely as variety of products can be made at the same time.? This has helped in the advancement of industry sector. Various CNC machine shops now also use CNC laser cutting machine for their production along with water jet cutting and CNC machines.

CNC milling finds application making a wide range of custom parts. CNC milling is a cutting process in which material is removed from a block metal or plastic by a rotating tool. In CNC milling the cutting tool (called a ?mill?) is moved in all three dimensions to cut a desired shape from stock.

In this process, the material is usually removed by both the end and the side of the cutting tool. Unlike a drill which removes material only from the end, in CNC milling the cutting tool rotates about an axis that is perpendicular to the table that holds the work. Cutting tools of various profile shapes are available including square, rounded, and angled. A wide variety of part shapes and geometries are possible. The most common are the ?end mill? which finishes to a flat bottom surface while a ?ball mill? has a rounded end.

A wide variety of 2D and 3D shapes are possible in the process. Some of the examples of CNC milling are engine components, custom jigs and mold tooling, complex mechanisms, enclosures, etc.

The thing CNC Milling does especially well is create complex shapes block material. While CNC milling can be used on 2D projects, there are lots of other choices for thin stock. Waterjet cutting and plasma cutting, for example, come to mind. But thick stock, needing metal removed? That?s where CNC milling shines. The CNC Milling process proves to be cost effective for short runs.

In the event you run into large production quantities, then you might wish to consider cast or forged parts.

When you set about designing a new custom part, keep a wide range of cutting machines in mind. Depending upon the production quantity you can model the cost of Laser Cutting, Turret Punch or Fixed punches, and the cast or forge decision.

The easy way to get started making custom CNC parts is to design them in free 3D CAD software available from www.emachineshop.com, the world?s first online machine shop. Once a part is draw, it can be assigned to different machines and prices and deliveries compared. If you like your design, eMachineShop is only too happy to build it for you.

What I used to do…

Before I found design software I was in the stone ages. I would actually hand lay out a template on a piece of paper. Then cut it out. Next, I would tape the design onto a piece of steel and trace around it with a Sharpe Marker. Finally, I would cut out the piece I wanted.

No matter what, it was never exact. There would always be something wrong. Things like wavy lines, gouges and “unique parts” were the norm. Measurements were never as exact as I would have liked either. That usually caused some fit-up issues, followed by some grinding. If you know anything about fabrication, grinding is the enemy of your time.

Why use Design Software?

I knew there had to be a better way so I found some design software to try out. Yes, it does take some time to learn. Think about it, like anything else in life, something that is worth it takes some time. This is also the situation of taking one step backwards to move ten steps forward.

Here are some advantages of using Design Software:

Saved file you can use over and over
Transfer the design to others
Can use exact measurements
Repeatability in design

Here are some disadvantages of using Design Software:

Cost money
Takes time to learn
May not be the quickest way of making something if it is a “One Off”

My Definition of Design Software

If you are an engineer, you will probably consider CAD Software as design software. That is true. But what I am talking about here is “Creative” Design Software. These software packages are used by creative types for print, web design and logo design. This software is great for creating designs that flow and are artistic in some way.

Design software can be boiled down to what it is good at. If you want to make a square with a hole in it or a triangular gusset, then CAD type design software works great. If you want to cut out a Cowboy on a Horse, then “Creative” Design Software is the only way to go.

Here are some examples of work for “Creative” Design Software:

Plasma Art
Router Art
Signs
Engraving

Every CNC machine has quirks that you need to learn. Every CNC machine has a different working envelope. Every CNC machine is just a little bit different then the rest of them. It is in your best interest to learn your machine before you put it to work.

Generally, with a CNC machine, we are machining something. While machining, “chips” are being thrown off. Sometimes at a very rapid speed. Here is where safety glasses, face shields and material barriers come into play. Use them! The machine doesn’t know you are standing there. In the words of every boxing ref before a match, “protect yourself at all times!”
