General CNC machining usually refers to precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc.

1. White steel knife speed should not be too fast.

2. Copper work to open the rough less use of white steel knife, more use of flying knife or alloy knife.

3. When the workpiece is too high, it should be layered with different lengths of knives for roughing.

4. After roughing with a large knife, application of small knives and then remove the remaining material to ensure that the balance is consistent before the light knife.

5. The plane should be processed with a flat bottom knife and less with a ball knife to reduce the processing time.

6. When copper workers clear the corner, first check the corner R size, and then determine how much to use the ball cutter.

7. The four corners of the calibration table plane should be gong flat.

8. Where the slope is an integer, the application of slope knife processing, such as the pipe bit.

9. Before doing each process, think clearly about the remaining balance after processing the previous process, in order to avoid empty knives or processing too many and knives.

10. Try to take the simple knife path, such as shape, grooving, single-sided, less to go around the same height.

11. When going WCUT, can go FINISH, do not go ROUGH.

12. When shape light knife, first rough light, then fine light, when the workpiece is too high, first light edge, then the light bottom.

13. Set the tolerance reasonably to balance the machining accuracy and computer calculation time. When opening coarse, the tolerance is set to 1/5 of the margin, and when light cutter, the tolerance is set to 0.01.

14.Do more processes to reduce empty tool time. Do a little more thinking, reduce the chance of error. Do a little more auxiliary line auxiliary surface to improve the machining condition.

15. Establish a sense of responsibility and check each parameter carefully to avoid rework.
