极值法在机械加工误差分析中的运用

The Application of Extremum Method in Machining Error Analysis

本文根据误差理论建立数学模型,运用曲线凹凸性判断方法分析工件形状和误差种类,提出了计算误差值的方法,指出了以往误差计算方法的不足之处。

This paper discusses how to build mathematical model on the basis of error theory and how to use concavity-convexity of curve to analyze the shape of a workpiece and the category of error. It puts forward a new method to calculate error and points out the dificiency of the previous methods.
