The intelligent measuring sub-system in the computer integrated and flexible laser processing system

摘要

Based on the computer integrated and flexible laser processing system, we developed an intelligentrnmeasuring sub-system. A novel model has been built to compensate the deviations of the main frame-structure,rnand a laser tracker system is applied to calibrate the accuracy of the system. Analyzing the characteristics of allrnkind surfaces of automobile outer penal moulds and dies, the surface and border to be measured and processed arernclassified into four types. A 2-D adaptive measuring method based on B?zier curve and a 3-D adaptive measuringrnmethod based on Spline curve are developed for different types of surface. During the data processing, a 3-Drnprobe compensation method is described in details. The control software of the sub-measuring system is described.rnSome measuring experiments are carried out to testify the methods.
