CNC computer gong programming matters needing attention

1. The speed of white steel knife should not be too fast.
2. Copper workers use less white steel knives and more flying knives or alloy knives.
3. When the workpiece is too high, it should be roughened by layers with knives of different lengths.
4. After roughening with a big knife, use a small knife to remove the remaining material to ensure that the remaining material is consistent.
5. The plane should be processed with flat bottomed cutter and less ball cutter to reduce the processing time.
6. When cleaning the corner, check the size of R on the corner first, and then determine the size of the ball knife.
7. The four corners of the calibration plane should be level.
8. Where the slope is an integer, the slope cutter shall be used for processing, such as pipe position.
9. Before each process, think about the remaining allowance after the previous process,

In order to avoid the blank tool or too much processing and knife.

10. Try to use simple cutting path, such as shape, trenching, single side, less walking around and so on.
11. When walking wcut, those who can walk finish should not walk rough.
12. When the shape of the knife is smooth, rough first and then fine. When the workpiece is too high, smooth the edge first and then the bottom.
13. Set reasonable tolerance 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 cutting.
14. Do more process to reduce the time of empty tool.

Do more thinking and reduce the chance of mistakes.

Do more auxiliary lines and auxiliary surfaces to improve the processing condition.

15. Establish a sense of responsibility and carefully check each parameter to avoid rework.
16. Be diligent in learning, good at thinking and make continuous progress.

17 milling non planar, more ball cutter, less end cutter, do not be afraid of the knife;

18 small knife clear angle, big knife refined;

Don’t be afraid of patching, proper patching can improve the processing speed and beautify the processing effect

20 high hardness of blank material: reverse milling is better, low hardness of blank material: forward milling is better

Good accuracy, good rigidity and finishing: it is more suitable for forward milling, otherwise it is more suitable for reverse milling

It is strongly recommended to use forward milling for finishing the inner corner of parts.

Rough machining: reverse milling is better, finish machining: forward milling is better

Tool material toughness is good, low hardness: more suitable for rough machining (large cutting amount processing)

Poor toughness and high hardness of tool material: suitable for finish machining (small cutting amount machining)
