摘　　要：传统的工件定位误差合成计算方法,首先需要人工进行几何分析,然后选择计算公式再进行计算,极易出错,也不便计算机进行数据处理。文中介绍了一种应用尺寸链原理,建立尺寸函数,进行工件定位误差计算的新方法。In the traditional composite calculation of workpiece location deviation, a preliminary manual geometric analysis is required and then a calulation formula is chosen before the real calulation. Such an approach easily causes errors, and data proessing by computer is not accessible. This paper introduces a new method of composite calculation of workpiece location deviation, that is, establishing a size function on the principle of loop function.
