摘　　要：轴套零件的加工工艺尺寸链求解是一个复杂的问题,工序多、定位基准变化大,绘制工序图繁杂,工序尺寸,尺寸公差的计算量大。传统工艺设计中通常运用手工绘图工序图并建立尺寸链方法求解,计算量大,效率低,易出错等因素;运用LU分析法,在计算机上编程计算求解,不仅实现计算机辅助工艺(CAPP)中工序尺寸和尺寸公差的自动化求解,而且可以提高效率。The dimension chain solution of parts processing technology is a complex problem.Many process and,the positioning dateline changes greatly.The drawing process diagram is complex.The shaft sleeve in several processes in the mechanical processing process involves the calculation of the process size.In traditional process design,manual drawing and dimensional chain are usually used to solve the problem.By using LU analysis and calculation method in computer programming calculation,can realize the computer aided process CAPP size automatic solution.
