In this article, let's explain what novices need to learn before learning CNC machining?

NC English CNC, the meaning of computer digital control, NC machining is CNC machining. The key here is to mention control. What is the control? Controls how to cut. Cutting what? Mainly metal.

Therefore, learning NC requires three skills:

1. Metal cutting

To know the characteristics, heating, overload, rotating speed and cutting depth of each layer of the tool to the material, the skills required are: metal materials, tool materials and types, mechanical analysis of the cutting ability of the tool to the metal. You can find some books in this regard. There are many in the bookstore. You should know what speed this knife should give to cut this metal material. How many millimeters can each minute run and how deep can each layer be processed. This problem can be solved by looking at ordinary milling machines or lathes.

2. Control part

This part is a pure software problem. If you think about how to cut and analyze thoroughly, you need software to control and produce the desired cutting method.

After selecting the surface or entity to be processed, many values are set in turn, such as depth control, how high to process from Z height, how deep each layer is processed, how to lift the tool between layers, processing range control, etc.

CNC machining

This part is software. After learning the command, you can learn it. It's dead. You can learn whatever you want to learn. By the way, it's a pity that there are so many professional CNC processing markets in China. We can't find a book with such a complete analysis. Many books just tell you how much to input here, how much to input there, next step, next step, OK, this is a typical plagiarized book. For programming, CNC induction is the most easy to understand tutorial. Dongguan CNC machining is recommended!

3. Processing technology

The so-called process is how to process and how to process. When you are familiar with the cutting ability of the tool to the material and understand that the software can control, the next problem is how to cut. For example, if you want to cut (process) a plane or a corner of a mold (part), how can you use the knife to make it brighter? Will it touch the fillet at the bottom, whether it is beautiful or not, and whether there will be any allowance to cut, etc. For this analysis, a master with actual CNC machining center should analyze each shape one by one with work experience. In the third step, process analysis, many institutions have talked about the first two points, so students will be in a fog after learning.
