Considering machining efficiency, a cutter with large enough diameter should be used in rough machining of 2.5 dimensional pocket with islands. In this case, the most portion of unnecessary material is to be machined by the large cutter and the rest of uncut portion, by a smaller cutter. The first problem is to generate tool path for the large cutter so that the cutter can remove raw material as much as possible without interfering with the contour of the pocket and islands. The next problem is to detect the uncut areas that are left by the machining of the large cutter. In previous researches about pocket machining, only simple cases of uncut area have been considered. In this paper, an algorithm of tool path generation for rough machining process is presented and also a detection algorithm of uncut areas that are left in the rough machining is proposed. For pocket with islands, both composed with lines and arcs, the proposed algorithm can detect all possib[e kinds of uncut areas correctly.
