1. The speed of the white steel knife should not be too fast.
2. It is best to use a flying knife or alloy knife for copper blanks, not a white steel knife.
3. When the workpiece is too high, it is best to use tools of different lengths to open the thickness in layers.
4. After opening the blank with a large knife, clean up the remaining material with a knife to ensure that the remaining material is consistent, and then cut it flatly.
5. Flat bottom cutter is used for plane machining, not ball nose cutter, to reduce machining time.
6. When clearing the corner, check the radius on the corner first, and then determine the size of the ball knife.
7. The four corners of the calibration plane should be on the same horizontal plane.
8. When the inclination angle is an integer, it should be processed with an oblique knife, such as a pipe position.
9. Before each process, the allowance after the previous process should be considered clearly to avoid empty knives or excessive processing.
10. Try to follow simple paths such as shape, chamfer, side, less circumference, etc.
11. When running WCUT, don't run ROUGH if you can run FINISH.
