Abstract

A method for calculating part conicity based on a minimum zone comprises the steps of firstly measuring and obtaining coordinates of measured points on the measured circular conical surface, then providing initial parameters of a cone, inquiring measured points of measured features in contact with an error tolerance zone, performing corresponding translation change, rotation change and size change of the error tolerance zone according to the number and coordinates of contact points, and calculating the change amount of the tolerance zone to sequentially find contact points meeting criterions of the minimum zone. By means of the method, a conicity error optimal value and a cone parameter optimal value can be accurately calculated.

Description

technical field

[0001] The invention relates to a method for calculating the conicity of parts based on the smallest area, which belongs to the field of precision measurement and computer application, can be used for the qualification detection of conical elements in geometric products in various situations, and provides for the improvement of the processing process and processing technology. guide. Background technique

[0002] Due to the advantages of good alignment, strong sealing, reliable fit, fast and accurate installation and positioning, the conical fit is widely used in mechanical geometric products. In actual production, traditional measuring instruments such as goniometers and cone plug gauges are generally used for qualification inspection. Although these methods are simple and easy to implement, the detection information is too single to meet the requirements of high-precision mechanical products, and there are certain limitations. With the wide application of...
