ALGORITHMS FOR AUTOMATED NON-CONTACT CONTROL OF GEOMETRIC CHARACTERISTICS AND ROUGHNESS OF PRODUCTS
ITMO University;
Abstract. The results of an experimental determination of the possibility of using optical laser triangulation to measure profile characteristics and evaluate the surface quality of parts with a multi-edge structure obtained by milling are presented. An algorithm for the formation and analysis of the profile of finned products by laser triangulation is developed and corresponding software is implemented to measure the geometric parameters of products, including linear, diametrical dimensions, finned parameters, and thickness. An algorithm for estimating the roughness of products with a developed surface obtained as a result of milling using a laser triangulation sensor has been developed implemented. Presented results of experimental testing of the algorithms confirm the effectiveness of using laser triangulation in technical control systems. This makes it possible to improve the manufacturing quality of complex shaped products and reduce the level of manufacturing defects by increasing the accuracy and information content of the control.
