CNC Programming – General Information
To successfully cut the metal and do various processes in manufacturing, we need to use CNC programming since they are a most effective way of doing this work. There is a huge number of people who are doing CNC programing to make metals, foam and woodworking objects for a hobby. CNC has created a way for many people to manufacture or fabricate parts quickly and effortlessly.
CNC stands for computer numerical control and is basically the use of a computer to do certain types of operations. And this type of process is usually used to router, lathe, laser machines and foam cutters – and the same process can be used for mini versions of these machines.
Actually, there are two main categories in which the CNC program will be placed, a continuous path positioning category or a point to point category. Depending on the sophistication of the software we are using, we can make computer to execute first and second type of programming. This means that the operator must understand both processes in order to run the machine.
Now you will have a chance to understand a bit more about these categories:
Point to point positioning – this category is mostly used when drilling, boring, punching or tapping is needed. We use this kind of process so we can position from one point to another while the machine process si being done. In other words, it works from the X to the Y position or to as many positions as it is instructed and keeps going until the process is finished.
Continuous path positioning – this category is generally used when a lathe or milling machine is being used and is used for contouring. And this is simply another name that is used for the category. Since the cutting tool will move constantly through all points, without stopping, the piece will be completed in one move. It is necessary that the operator knows how to program the machine so it can continue to work on several axes in the sime time.
If we understant these two processes perfectly, we will have better results on the work we do.
