切削加工过程最佳化是指在工艺系统一定的条件下,如何确定最合理的切削用量的问题。切削用量确定得是否合理直接关系着零件的生产率和成本。切削用量太低,使生产率降低,成本提高;反之,切削用量太高,使刀具磨损加剧,刀具损耗增多,换刀、磨刀等辅助时间增加,结果也使生产率降低,成本提高。另外,切削用量的大小还会影响零件的质量。 Cutting process optimization is the process system under certain conditions, how to determine the most reasonable cutting the amount of problems. Determining the amount of cutting is directly related to the productivity and cost of parts. Cutting the amount is too low, so that productivity is reduced, the cost increase; the other hand, the amount of cutting is too high, so that tool wear increased, tool wear increased, tool change, sharpening and other auxiliary time increases, resulting in lower productivity and higher costs. In addition, the amount of cutting the size will affect the quality of parts.
