Advantages of CNC machining

1. A large number of cutting tooling, processing parts with disordered shapes do not need messy tooling. If you want to change the shape and scale of parts, you only need to modify the part processing program, which is suitable for new product development and modification.
2. The machining quality is stable, the machining precision is high, and the repetition precision is high.
3. In the case of multi type and small batch production, the production power is higher, the time of production preparation, machine tool adjustment and process inspection can be reduced, and the cutting time can be reduced by using the optimal cutting amount.
4. It can machine the disordered surface which is difficult to machine by conventional method, and even can process some parts which cannot be observed.

The defect of NC machining is the high cost of machine tools, 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 experience summary of CNC application in various industries is worth learning. The following points are summarized:

1. The speed of white steel knife should not be too fast.
2. Copper roughing less white steel knife, more use flying knife or alloy knife.

CNC machining

1. When the workpiece is too high, it should be sliced with different length of knife.
2. After roughening with a large knife, use a small knife to remove the remaining material, and smooth the knife only after ensuring the same allowance.
3. The plane is processed with flat bottom cutter and less ball cutter, so as to reduce the processing time.
4. When the copper worker cleans the angle, first check the R size on the angle, and then determine how large the ball knife is used.
5. The four corners of the calibration plane should be smooth.
6. If the slope is an integer, use the slope cutter to process, such as pipe position.
7. Before each process, think about the remaining allowance after the previous process to prevent the tool from being empty or excessive.
8. Try to take simple cutting path, such as shape, grooving, single side, less walking around the same height.
9. When taking wcut, if you can walk finish, don’t go rough.
10. 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.
11. Set tolerance reasonably to balance machining accuracy and computer calculation time. The tolerance is set to 1 / 5 of the allowance for roughening and 0.01 for smooth knife.
12. Do more procedures and cut down the idle time. Think more and cut down on mistakes. Make more auxiliary lines and auxiliary surfaces to improve the processing conditions.
