Abstract
The invention discloses a five-axis flank milling system for machining curved surface and the method thereof, the system is capable of planning the path in accordance with the overcut or undercut with the control of the total amount of the machining error. The amount of overcut, undercut, or total machining error can be precisely controlled by adjustment of tool path. The invention is to transform tool path planning in five-axis flank milling into an optimal matching problem. The weighted sum of overcut and undercut serves as the objective function in the optimization process. By properly changing the weights, the distribution of overcut and undercut on the machined surface is modified to meet different machining requirements. Smaller machining errors are thus obtained compared with the results of previous methods. The proposed mechanism of the invention significantly improves the manufacturing capability of five-axis flank milling. It enhances the machining quality of the key components in industries.
