工艺系统误差对机械加工精度的影响探讨

Influence of Process System Error on Machining Accuracy

工艺系统中存在的误差特性,主要包括几何外形误差、温差变化破坏外形引起的误差以及残余内应力造成的误差等。此外,在机械运行过程中会不可避免地产生各种各样的误差。所以,在日常的机械生产过程中,需要依据实际情况把握最主要的矛盾,以保障良好的机械加工精度。

Referring to the error characteristics in the process system,it can be classified scientifically,mainly including:geometric shape error,error caused by temperature difference change to destroy the shape and error caused by internal residual energy,etc..In addition,all kinds of errors will inevitably occur during the operation of the machine.Therefore,in the daily mechanical production process,we need to grasp the most important contradiction according to the actual situation,to ensure a good machining accuracy.
