摘要： In a conventional CAM apparatus, cutting regions and a tool axis angle by which the cutting time is minimized cannot be automatically set for a finish shape having a free formed surface shape. Accordingly, the CAM apparatus generates quadrangle-shaped patterns of cutting regions using coordinate data of a finish shape and an initial shape. Triangle-shaped cutting regions are generated for concave-convex faces of the finish shape. For cutting regions generated by subtraction by boolean operation with a subtract shape calculated by subtraction by boolean operation between the initial shape and the finish shape, the tool axis angle is set so that the tool does not interfere and the face is maximized. For other regions, the tool axis is set so as to satisfy a remainder standard and to minimize a tool path length.
