平面尺寸链公差计算的简便方法

Simplified Calculating Method for Tolerance in Plane Size Chain

应用多元函数的偏微分理论和工艺尺寸链原理 ,提出一种简化平面尺寸链公差计算的方法 ,应用此方法可以简捷地计算平面孔系尺寸公差及平面尺寸链中的其它尺寸公差。

By using the partial differential theory and technological size chain principle of multivariate function,this paper puts forward a simplified calculating method for tolerance in plane size chain,through which people can calculate the plane system size tolerance and other size tolerances in plane size chain.
