So beginners need three skills to learn cnc:
1. Metal cutting
As a programmer, it is necessary to know about metal materials. At least in the process of programming, we should know the characteristics, heating, overload, rotational speed and cutting depth of each layer of the milling cutter. The skills required are: metal materials, milling cutter materials and types.
You should know the speed at which this knife cuts this metal material. How many millimeters can you run per minute and how deep each layer can be processed.
2. Control part (programming part)
This part is a pure software problem, and it is also a key problem. How to cut, think it over, and analyze it thoroughly, we must control it by software to produce the desired cutting method. After selecting the surface or solid to be machined, set many values in turn, such as depth control, how high to machine from Z height, how deep to machine each layer, how to raise and lower the interlayer cutter, machining range control and so on.
This part is software. After learning the command, it will be ok. This is fixed. Anyone who wants to learn can learn. By the way, it's a pity that China has such a big market. I can't find a complete book on this analysis. Many books just tell you how much is in here, how much is in there, the next step, the next step, OK. So many people who want to learn CNC programming well will buy some books to read, but they just can't learn, let alone learn. Because everything in the book is good fur, I can only give a brief introduction. At this time, it is recommended to go to some formal CNC training institutions.
3. Processing technology part
The so-called process is how to deal with it and how to deal with it. When you are familiar with the cutting ability of the tool and understand that the software can control it, the next step is how to cut it. For example, if you want to cut (process) a plane or a corner of a die (part), how can you cut it brighter, whether the bottom will touch the fillet, whether it will be beautiful, whether there will be a margin for cutting, and so on. For this kind of analysis, the master with practical processing experience should analyze each shape one by one with work experience. Really learn CNC core in the third step, process analysis. The process part is also the key and difficult part in NC machining. This part is the link that best reflects the technical level and experience of a technician. It is also a measure of wages. Those who have skills and experience and can solve production problems have high natural wages. In China, especially in Shenzhen, a good programming technician can reach the stage of 8000- 15000.
In a word, the above three points are essential for beginners to learn CNC programming well. In fact, the above three points are just general learning directions, which contain too many things and involve too many technologies. It's better to find a formal training institution to study and improve systematically than to study painfully.
