General CNC machining usually refers to computer digital control of precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc. Shenzhen cnc machining when the workpiece overcut cause how to improve?
Cause.
Play knife, tool strength is not long enough or too small, resulting in tool play.
Improper operation by the operator.
Cutting allowance is not uniform. (e.g. leave 0.5 on the side of the surface and 0.15 on the bottom)
Improper cutting parameters. (e.g., tolerance too large, SF set too fast, etc.)
Improvement.
Use knife principle: can be large, not small, can be short, not long.
Add corner cleaning procedures, and leave an even margin as much as possible. (Side and bottom margin left the same)
Reasonable adjustment of cutting parameters, the margin of large corners rounding.
Using the machine SF function, the operator fine-tune the speed so that the machine cutting to achieve the best results.
