In this report, the work shape is supposed as a polyhedron constructed by many sides connecting adjacent discrete points with lines. The summary of tool path calculation method using TSMM (Tangent Slope Matching Method proposed in our previous report) is described. One side slope method and two side slope method are shown as the utilization of tangent slope information of work. The tool path calculated by one side slope method causes machining error. This machining error (over-cut) is estimated theoretically. A work with half cylinder surface is cut by a ball end mill cutter using one side slope method and two side slope method. The machined surface of work is measured by CNC three-dimensional coordinate measurement equipment and compared with the theoretical shape.
