基于公差原则的确定形位公差的图解法

Graphic Method for Determining Form and Position Tolerance Based on the Tolerance Principle

根据公差原则并应用偏差和公差理论 ,提出一种基于公差原则的确定形位公差的图解法。应用此图解法可以在公差原则的范围内利用尺寸偏差和形位公差的关系简捷。

A graphic method for determining form and position tolerance is presented based on the tolerance principle and deviation and tolerance theory. By this graphic method,the permissible value of form and position to lerance can simply and exactly be determined using the relation of size deviation and form and position tolerance in the range of tolerance principle.
