机械加工误差的分析

Analysis of Machining Errors

机械加工误差是指零件加工后实际参数与设计参数存在的偏差,参数差距越小,加工误差越小,加工精度越高。在实际机械加工中,产生加工误差的因素有很多,如工艺流程、定位、工具使用、内应力等,因此,对机械加工工艺技术基本情况进行概述,重点分析导致机械加工误差的影响因素,并提出具体机械加工误差的误差控制措施,以期为相关从业者提供一定参考。

Machining error refers to the deviation between the actual parameters of the part and the design parameters after machining,and the smaller the parameter gap,the smaller the machining error and the higher the machining accuracy.In actual machining,there are many factors that produce machining errors,such as process flow,positioning,tool use,internal stress,etc.Therefore,an overview of the basic machining process technology is given,with emphasis on analyzing the influencing factors that lead to machining errors and putting forward error control measures for specific machining errors,in order to provide some reference for relevant practitioners.
