零件纵向厚度的计算方法

在用车床加工空心旋转体零件时，通过测量我们可以得出外轮廓曲线，但根据零件的设计技术要求，不同点处的法向厚度不同，因此在用车床加工时需要计算出各点的纵向厚度。本文给出了根据法向厚度及外曲线计算纵向厚度的方法．该方法简单、可靠，易于计算，而且由此方法计算的结果应用到实际加工时，效果非常好，该方法实用性强，易于推广使用。

Vertical thickness calculation of parts

When lathing hollow spinning spare parts,we can get its outline curve by measurement.But its normal thickness is different at different point in accordance with the technical requirement of the design of spare parts. So that we need to calculate its vertical thickness at different point simultaneoes.This paper presents the method with which vertical thickness can be worked out according to normal thickness and external curve .This method proves to be simple, reliable, easy operating and practical , furthermore using this method will produce accurate results.
