金属切削加工中,切削量的选用是一个难点。对切削用量的合理选择,是在对机床加工条件诸要素和加工要求、加工成本等因素的全面的分析考虑后,进行的合理选择,而不是孤立地从某个角度的考量。加工条件和要求存在两面性,有利的和不利的,长处和缺点,对加工因素的利弊权衡,趋利避害、扬长避短,是切削用量选择的策略。
In metal cutting, the amount of cutting is a difficult choice. The reasonable choice of cutting dosage is based on the comprehensive consideration and consideration of various factors such as machine tool processing conditions, processing requirements and processing cost, and makes a reasonable choice instead of considering it from an angle in isolation. Processing conditions and requirements of the existence of two sides, favorable and unfavorable, strengths and weaknesses, the advantages and disadvantages of processing factors trade-offs, the advantages and disadvantages, avoid weaknesses, is the choice of cutting strategy.
