What is CNC process?

CNC, also known as computer gong, cncch or CNC machine tool, is actually a kind of name in Hong Kong. Later, it was introduced into the Pearl River Delta of mainland China. It is actually a CNC milling machine. In Guangzhou, Jiangsu, Zhejiang and Shanghai, there is a new type of machining skill called “CNC machining center”. It is a new type of processing skill. The primary task is to compile the processing program, that is, to convert the original handicraft into computer programming. Of course, you need to have the experience of craft processing.

The disadvantage of NC machining is the high cost of machine tools and equipment, which requires high level of repair personnel.

CNC, also known as processing center, has a wide range of applications, not limited to furniture production. Therefore, the summary of CNC use experience in various industries is worth learning. The following points are summarized:

1. The speed of white steel knife is not too fast.
2. Copper roughing less white steel knife, more use flying knife or alloy knife.
3. When the workpiece is too high, it should be sliced with different length of knife.
4. After roughening with a big knife, use a small knife to remove the remaining material to ensure that the surplus is common.
5. The plane is processed with flat bottom cutter and less ball cutter, so as to reduce the processing time.

CNC machining

1. When the copper worker cleans the angle, first check the size of R on the angle, and then determine how large the ball knife is used.
2. The four corners of the calibration plane should be smooth.
3. If the slope is an integer, use the slope cutter to process, such as pipe position.
4. Before each process, think about the remaining allowance after the previous process to prevent the tool from being empty or excessive.
5. Try to take simple knife path, such as shape, grooving, single side, less winding, etc.
6. When taking wcut, if you can walk finish, don’t go rough.
7. When the shape of the light knife is smooth, first rough and then fine. When the workpiece is too high, polish the edge first and then the bottom.
8. Reasonably set up the public service to balance the machining accuracy and computer calculation time. For roughing, the service is set to 1 / 5 of the allowance, while for the light knife, it is set to 0.01.
9. Do more procedures and cut down the idle time. Think more and cut down on mistakes. Do a little more auxiliary line, auxiliary surface, improve the processing situation.
