Cutting pattern registration method for free form surface machining
A problem of generating tool path for free form surface machining with optimized tool path topology is addressed in this paper, while the machining efficiency is maximized as much as possible. Using this method, the global property of the tool path (I.e., its topological feature) can be controlled while the detailed cutting direction at every local position yields large material removal. The planning of the tool path consists of three stages. Based on the analysis of the geometric properties of the machined surface and the cutter orientation, an optimal machining direction field in the two dimensional parametrical space of the machined surface is first generated. As this initial direction field is often irregular spaced or contains outliers caused, a functional optimization problem with linear filtering is solved to obtain an approximation of this initial direction field in the least square sense. Based on curvature analysis, the approximation field can be further classified into four types of direction fields, each of which can be registered with an adequate cutting pattern. Simulation is given to demonstrate the validity of the proposed method.
