Problems solved by technology

[0006] However, in the process of filling in the dimensions and tolerances, it may happen that the dimensions of the components are incorrectly judged or the direction of the dimension chain is incorrect.
This will make the dimensional chain unable to meet the closed requirements, resulting in errors in tolerance analysis

Abstract

A computer graphic tolerance detection system and a method adopted by the system are applied to processing that a drawing program captures dimension chain tolerance of a local element. The computer graphic tolerance detection method comprises the following steps of selecting the local element; optionally selecting a target point from the selected local element; using the target point as a reference and selecting the dimension chain direction; selecting a feature point from the local element in the dimension chain direction and calculating a separation distance between the target point and the feature point; using the feature point as a reference to repeat the step of calculating the separation distance between the target point and the feature point; recording the feature points and the corresponding separation distances in a tolerance analysis sheet.

Description

technical field [0001] The invention relates to a detection system and its method, in particular to a computer drawing tolerance detection system and its method. Background technique [0002] Tolerance analysis refers to rationally defining and distributing the tolerances of components and products under the premise of meeting the requirements of product function, performance, appearance and assemblability, optimizing product design, and manufacturing products with the lowest cost and the highest quality. [0003] As a very useful tool in product design for manufacturing and assembly, tolerance analysis can help mechanical engineers: realize reasonable setting of component tolerances to reduce component manufacturing costs, judge component assemblability, and determine whether components occur during assembly Interference and judge whether the key dimensions of the product after component assembly meet the requirements of appearance, quality and function. [0004] When it i...
