Speed optimization method for complex curved surface contact type tracking scan and measurement

Abstract

The invention discloses a speed optimization method for complex curved surface contact type tracking scan and measurement, which belongs to the technical field of complex curved surface type part measurement. With the speed optimization method, a measured complex curved surface part is subjected to tracking scan and measurement path planning, and the traditional tracking scan and measurement control algorithm is combined with a control mobile attenuation code (CMAC) learning controller so as to predict and regulate the tracking scan speed in advance. The bulb space coordinate of each sampling point serves as an input condition of an artificial cerebellar articulation model controller, a measuring head deviator value is used as a CMAC learning condition, and a CMAC output weight is regulated by a learning module. According to the speed optimization method, the measurement efficiency of the complex curved surface with a welding line and a cusp area can be drastically improved without improving the hardware system response performance of measurement equipment. The speed optimization method for the complex curved surface contact type tracking scan and measurement has the advantages of low cost and strong practicality.
