CNC Process Overview

2007-12-24T03:28:00.000-08:00

This is how I view CNC. I break it down into simple steps that I can remember. Now, they all interact, but it is good to keep them in boxes for simplicity sake. I also like to keep them in a logical, progression type order. Here they are:

Design, CAD, CAM, Control and Machine.

The software gets better every year. At one time large companies could only afford this technology. Now there are hundreds of thousands of these machines working in garages like yours and mine.

There are basically five elements to a CNC Project that you need to know:

Design - thinking and planning what you want to build
CAD - translating it into the computer
CAM - converting it into machine language
Controlling - directing your machine's motion
Machining - building the part to specifications

These five elements are really the building blocks to a CNC project. As you see them above, that is generally the order people associate them in. For example, you can't control until you have a design. You can't use your CAM software before your CAD software.

CNC Router Machine

The CNC router machine cuts in three directions at once. The precision of the router’s cutting relies on the design software, software that provides a two-fold advantage to the router operator.

To begin with, the CAD software

gives the operator of the CNC router machine the ability to create the design that will be cut into the solid plate.

After the operator creates the design, that same operator relies on the computer to send the proper operating instructions. The instructions from the software send signals to the router motor drive. These signals, termed tool path files, allow the motor controls to direct the precise motion of the router drive system.

The router bits perform the cutting of the CNC router machine. These bits are similar to drill bits. As mentioned above, the cutting can proceed along three different axes simultaneously. The CNC controls cause the movements of the drill bits to take place in small and precise increments.

The cutting along the x-axis moves from front to back. The cutting along the y-axis moves from left to right. The cutting along the z-axis moves up and down. The ability of the CNC router machine to move in 3 directions at once leads to the creation of interesting patterns and shapes.

The use of a CNC router machine guarantees savings in time and money. The CNC router machine produces each of its elaborately shaped products in a very small amount of time. In addition, the CNC router machine eliminates the need for an employee to stand at the router.

CNC Machining

CNC machining in the industrial the context refers to Computer Numerical Control. Computers are used to control machine tools for the purpose of manufacturing complex and intricate parts of metal and other material. More over the cutting

process is enabled, using a program written in a notation confirming to EIA-274-D standard, which is often referred as G-code.

The computer numerical controls were developed in late 1940’s and 1950’s, but were briefly preceded due to less advanced numerically controlled machines. However the CNC technology has developed greatly, with advances in mechanics and the computer sector. The developed CNC machines have drastically changed the face of the manufacturing industry.

More over the CNC structure has dramatically reduced human intervention in machining. It is easy to cut curves or straight lines, and structuring intricate 3-D parts has become relatively easy.

However CNC machines have helped to increase automation of the manufacturing sector, and have enabled improvements in consistent and quality production. The machininig technology has even helped significantly in reducing the frequency of errors and has provided the CNC operators with time to perform additional tasks.

CNC Cutting Machine

A good quality CNC cutting machine has a cutting table that covers the area bounded by a length of four feet and a width of eight feet. A quality table can handle satisfactorily a standard 4 x 8 plate of metal, wood, plastic,

glass, or stone. A table that lacks a sufficient length or width will make it necessary for the operator to repeatedly reposition the plate. Operators of the CNC cutting machine refer to such repositioning as indexing.

A good basic CNC cutting machine does both plasma and oxyfuel cutting. Refinements on a basic cutting machine might provide it with the ability to perform other functions, functions such as:

spotting holes for drilling
drilling aluminum
cutting a shape in the sides or end of tubing
routing wooden shapes

Other modifications on a CNC cutting machine might be directed at installation of the equipment for laser or water jet cutting.

The selection of a CNC cutting machine will be primarily determined by the nature of cutting that will be performed by the machine operator. For some operations, it will be necessary to do only straight cutting.

For other operations, the cutting machine must perform bevel cutting. Bevel cutting allows the operator to trim, reduce, shave, and pare the material in the plate.

CNC Machines

What is a CNC Machine? CNC stands for Computer Numeric Control. Sounds complicated, but it isn’t. Years ago, it was just NC, or Numeric Control. Since, they’ve added computers to control the machine.

In the simplest of terms, think of a drill press. It’s a machine that

drills holes. But before you can drill the hole, you have to loosen the chuck, install the correct drill bit, drill the hole in the correct place, turn off the drill, and remove the drill bit. Manually, this could be time consuming and cause fatigue over the course of numerous parts. This is a simple example, but throw in some lathe or milling machining and you have a greater chance for error.

With the CNC machine, all of this drilling can be done automatically instead of the manual process listed above. Machining has to be precise, and whether you use a CNC lathe or milling machine, you have to make sure the part is right. The computer takes a lot of the guesswork out of the machining of these parts. In fact, a CNC programmer can sometimes get bored watching the machine do all the work.

But there is more programming for the machine than you would think. The operator has to enter a set of instructions. The programming uses about 50 words and tells the machine how fast, how deep, and location for machining.

What can you do with a CNC machine? In manufacturing, you can use this tool for milling, drilling, reaming, boring and counter boring. You can also groove and thread parts in a CNC turning center. You may have several setups including CNC lathes, CNC drill and tap area, CNC milling, or even CNC grinding.(ezinearticles.com)
