1. The speed of the white steel knife cannot be too fast.
2. The copper work is thicker and less white steel knife, and more use of flying knife or alloy knife.
3. When the workpiece is too high, it should be layered with different lengths of knife to open.
4. After roughing with a large knife, apply a small knife to remove the remaining material to ensure that the remaining amount is the same.
5. Plane application of flat-bottom knives, less ball knives to reduce processing time.
6. When the copper is clearing the angle, first check the R size on the corner and then determine how big the ball knife is.
7. The four corners of the school plane should be flat.
8. Where the slope is an integer, apply a pitch knife, such as a pipe position.
9. Before doing each process, think about the remaining amount after the previous process is processed to avoid empty knives or excessive machining.
10. Try to take a simple path, such as shape, groove, single side, less walking and so on.
11. When going to WCUT, if you can take FINISH, don't take ROUGH.
12. When the shape is light, first coarse light, then fine light, when the workpiece is too high, first light edge, then light bottom.
13. Set tolerances reasonably to balance machining accuracy and computer calculation time. When roughing, the tolerance is set to 1/5 of the margin, and when the knife is used, the tolerance is set to 0.01.
14. Do a little more work and reduce the emptying time. Do a little more thinking and reduce the chance of error. Do a little more auxiliary line auxiliary surface to improve processing conditions.
15. Establish a sense of responsibility and carefully examine each parameter to avoid rework.
16. Diligent in learning, good at thinking, and continuous improvement.
Milling non-planar, multi-purpose ball knives, less end knives, don't be afraid to pick up knives;
Knife clear angle, big knife intensive;
Don't be afraid to make up the face. Appropriate make up can improve the processing speed and beautify the processing effect.
The hardness of the blank material is high: the hardness of the blank material is low, and the hardness of the blank material is low: the milling machine is better, the precision of the machine tool is good, the rigidity is good, and the finishing is better: it is more suitable for the down-cut milling, and vice versa. It is better to use the down-cut milling for the finishing of the inner corner of the up-cut part. .
Roughing: better up-cut milling, finishing: better tooling, good toughness and low hardness: more suitable for rough machining (large cutting capacity)
Tool material has poor toughness and high hardness: more suitable for finishing (small cutting amount processing)
