摘要
在零件的加工过程中,考虑工件的装夹、测量等因素,有时并不能按加工图纸所标注的尺寸直接加工,需要在加工前进行工序尺寸的换算,就如何判定在什么情况下需要进行工序尺寸的换算?以及如何运用尺寸链原理进行工序尺寸的计算进行了详细的阐述,对于解决生产中工序尺寸的确定问题具有一定的实用意义。
tin the process of parts processing, to consider such factors as the workpiece clamping and measuring of, sometimes cannot directly according to the machining drawings with the size of the processing, the need to be done before the processing of the conversion process dimension, this pa-per is how to determine under what conditions need to be the conversion of process size？ And how to use the calculation of dimension chain principle procedure dimension has carried on the detailed elabo-ration, to solve the problem in production process determine the size Of a certain practical significance.
