It would not be an understatement to state that CNC is the heart and soul of many production units. By using CNC, the simplest things like stencils to the complicated things custom made jewelry can be produced without any flaws. Today we are using a lot of things with very complicated and minute designs it is all because of the use of CNC. There is no way that man can make anything with such accuracy. Here are a few things that you need to know about CNC.
The codes that are used to program the CNC machines are called as G-codes. It is more like the programming language for CNC machines. The operations of the machine are entirely based on the G-codes that are entered. Each and every parameter of the design is achieved by using appropriate codes. All of the actions of the machine, which includes the speed of the tool, the position of the tool and a lot of other things are entirely based on the coding that is done. These G-codes are programmed using CNC control software.
The beginning – CAD
The beginning of CNC – Computer Numerical Control begins with CAD. CAD stands for Computer Aided Design. It is the initial process where the product is designed in two dimensions or in three dimensions. After having the trial run the G-codes are determined. The trial is a process through which all the mistakes are eliminated completely. This is called as the cutting air. It does not just eliminate the mistakes in the designing process, but it also prevents all kinds of damage to the tool, the machine, and the workpiece. If the program is successful, then the exact program can be run to machine the real workpiece.
We all know for a fact that simple products can be manufactured using a lathe. But if the design is way too complicated, there is no way that it can be precisely produced by a human. This is where CNC comes into play. It does not matter how much complicated the designs are, with accurate codes every minute detail involved in the product can be produced without any flaws. The best part is that you can use the same program to produce multiple products. On a daily basis, we use a lot of products that are manufactured using CNC.
If you are able to design the product on the computer, then it can be produced using CNC. It does not matter if the design is way too complicated. If it is a 3D design, then a 3-Axis CNC machine can be used which moves in all three axis X, Y and Z-axis. For more complicated designs there are 4-Axis CNC machines, 5-Axis CNC machines and 6-Axis CNC machines.
