摘要
制订零件加工工艺规程时需标注工序尺寸,确定工序尺寸有两种方法:一是定位基准与设计基准重合时,确定比较简单;二是当定位基准与设计基准不重合时,应按尺寸链原理来计算,尺寸链从几种不同的情况来进行分析计算。
When working out the technological process of parts, you need label the procedure measurements. There are two ways to determine the procedure measurements: when location standard coincide with design standard, it is easy to determine; if not, it can be calculated according to its dimension chain principle. Dimension chain should be analyzed and calculated from several different circumstances.
