Abstract
In this study, we propose a new automatic planning method of tool posture for continuous 5-axis machining, which can avoid collision between spindle shape and machined workpiece surface. In the proposed method, shape of the machined workpiece surface is simulated with voxel representation. Then interference among the voxel shape and took holder and shank shape are estimated by each tool moving step. Then, the interfered tool posture is modified to new tool posture without collision. In the proposed method, we developed a new efficient algorithm to set and detect new candidates of tool posture. As a result, the proposed method can realize both avoidance of rapid tool posture change and reduction of computational time to plan a new tool posture.
