Outline of Final Research Achievements

A Mathematical model for the optimization of cutting tool posture is constructed in order to aid the path planning in machining operations by multi-axis production resources such as 5 axis machine tools, robots and so on. In this research project, the previous model proposed by the applicants is modified to cope with more complicated 3D-formed products, or the actual industrial products. The model includes non-linear equations in the constraints, therefore a heuristic searching approach is also examined to obtain one of feasible solutions. In order to clarify the availability of the proposed method, a solution for puzzle ring, which is the relative postures between two wired rings moving to avoid their collisions, is shown as the example.
