- The speed of the white steel knife should not be too fast.
- Coppersmiths use less white steel knives for rough cutting, and more use flying knives or alloy knives.
- When the workpiece is too high, you should use different length cutters to cut the thickness.
- After roughing with a big knife, use a small knife to remove the remaining material to ensure that the remaining amount is consistent.
- Flat-bottomed knives are used for plane machining, and ball knives are used less to reduce machining time.
- When the copper worker cleans the corner, first check the size of the R on the corner, and then determine the size of the ball knife to use.
- The four corners of the calibration plane should be flat.
- Where the inclination is an integer, use the inclination knife to process, such as pipe position.
- Before doing each process, think about the margin left after the previous process is processed, so as to avoid empty cutters or excessive processing.
- Try to take simple toolpaths, such as shape, grooving, single-sided, and less surrounding height.
- When walking WCUT, if you can go FINISH, don’t go ROUGH.
- When the shape of the light knife is rough, polish first, then polish. When the workpiece is too high, polish the edges first, then polish the bottom.
- Set tolerances reasonably to balance processing accuracy and computer calculation time. For roughing, the tolerance is set to 1/5 of the margin, and for light knife, the tolerance is set to 0.01.
- Do more procedures to reduce the time of empty knife. Do a little more thinking to reduce the chance of error. Do a little more auxiliary line auxiliary surface to improve the processing condition.
- Establish a sense of responsibility, carefully check each parameter, and avoid rework.
- Diligent in learning, good at thinking, and continuous improvement.
- For non-planar milling, use ball cutters more and less end cutters. Don’t be afraid to pick up the cutter.
- A small knife is used to clear the corners and a large knife is used for fine repairs.
19.Don’t be afraid of making up the noodles. Proper noodle making can increase the processing speed and beautify the processing effect.
- The rough material has high hardness: up-milling is better
- The rough material has low hardness: down milling is better
- The machine tool has good precision, good rigidity, and finishing: more suitable for down milling, and vice versa.
- It is strongly recommended to use down milling for finishing of inner corners of parts.
- Rough machining: up-milling is better, finishing: down-milling is better (it is best to avoid backwashing, which can damage the tool, especially hard materials)
- Tool material has good toughness and low hardness: more suitable for rough machining (large cutting amount machining)
- The tool material has poor toughness and high hardness: it is more suitable for finishing.
