Abstract
This study deals with a new planning method of minimum shank length for multi axis control machining. In conventional method, it is designed to deal 3+2 axis control machining and it assumes that tool posture is fixed in machining process. In this paper, we focus on continuous control machining and propose a new planning method based on parallel processing with general purpose graphics processing unit (GPGPU). In the proposed method, required shank length to avoid collision between polygon as approximated shape of workpiece and tool holder is calculated in each polygons individually. Then, the minimum shank length for each tool posture is estimated by comparison among the required length for each polygons. In this paper, we mention about the algorithm of the proposed method and explain the developed prototype estimation system. The developed system can detect the minimum shank length for each tool posture on continuous multi-axis control machining within a few hundred milliseconds.
