- The speed of white steel knife should not be too fast.
- Copper workers use less white steel knives and more flying knives or alloy knives.
- When the workpiece is too high, it should be roughened by layers with knives of different lengths.
- After roughening with a big knife, use a small knife to remove the remaining material to ensure that the remaining material is consistent.
- The plane should be processed with flat bottomed cutter and less ball cutter to reduce the processing time.
- When cleaning the corner, check the size of R on the corner first, and then determine the size of the ball knife.
- The four corners of the calibration plane should be level.
- Where the slope is an integer, the slope cutter shall be used for processing, such as pipe position.
- 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.
- Try to use simple cutting path, such as shape, trenching, single side, less walking around and so on.
- When walking wcut, those who can walk finish should not walk rough.
- 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.
- 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.
- 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.
- Establish a sense of responsibility and carefully check each parameter to avoid rework.
- 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)
