在夹具中加工时工件的精度分析

The Machining Precision of Workpieces with Jig aod Fixture

本文对加工工艺系统中影响加工精度的各项误差作了新的定义。单独列出了夹具的制遣误差△Z,这样有利于夹具总图上尺寸公差和技术要求的标注和夹具制造精度的控制。本文列举了加工精度分析计算的实例。

This article gives new definitions to various errors which impair the machining precision in technological system.△Z ——the manufac- turing error of jig and fixture is set out separately,which could be in favor of putting the sizes' tolerances and technical requirements on the assembly drawing of jig and fixture,and controlling the manufacturing psecisions.An example of analytical calculation of machining precision is given in the paper.
