Shape and position tolerance question and answer
1. What are the basic principles for a given shape tolerance? A: A pattern is a tool for conveying design information. Therefore, pattern drawing, dimensioning, dimensional tolerances, geometrical tolerances, etc. should be used to express the designer's function of the part. The requirements reflect the design intent as the basic principle. The process requirements of the part and even the inspection method should not be taken as the basic principle of the given shape tolerance. The method of measuring the tolerance of the shape is determined by the method or method that is too backward.
