Abstract
This invention provides a method of planning path for a curved surface cutting process based on global optimization. Its main characteristic is to convert the problem of motion planning of a cutter in a three-dimensional space into a mathematical planning problem of the corresponding relationship between two independent curved lines so as to obtain the final path for the curved surface cutting process by finding the solution with the global optimization mathematical model. Therefore, it can accurately control the error of the path for the curved surface cutting process and, given that different types of error value conditions are satisfied, automatically generate the best cutter path in order to provide precise and flexible path planning functions. The method of planning path for a curved surface cutting process can greatly improve the processing and manufacturing process capability in such industries as aerospace, automobile, marine, air-conditioning, and mold manufacturing.
