The external cause of workpiece overcut is often insufficient tool strength or inappropriate size, while the internal cause may be that the operation is not standardized, the cutting data is not set properly, and the cutting allowance setting is uneven, resulting in too large tolerances, and finally causing the workpiece to be overcut and producing machining errors.
To solve this problem, the margin is left as uniform as possible when adding the corner clearing program, the tool is used as large as possible, and the SF function of the vertical machining center is used to fine-tune the degree to gradually achieve the best cutting effect.
