Milling process simulation based on quadtree-array representation

Model representation of workpiece in machining process simulation does directly influence on simulation accuracy and efficiency. The algorithm to acquire cutting width and cutting depth based on quadtree-array representation is discussed in this paper. In milling process simulation, workpiece is represented with quadtree-array and the cutting width and cutting depth are predicted real-time. The results of controlled simulation shows that the predicted cutting depth is accordance with that of the designed and the predicted cutting width is close to that of the designed within accuracy of half a discretization interval.
