자유곡면 모델을 이용한 황삭 가공용 NC 데이터 생성에 관한 연구

A Study on NC Rough Machining Data Generated by the Free-Form Surface Model

This study suggested in silheop, machining allowance, a tool information and tool path is to create a gap, such as contour parallel tool paths from the input information. In this paper, we study the roughing machining CAM system with Z-map method, such as rough machining tool path method proposed in the course of the experiment, the three-dimensional contour toolpath, raw processing areas, 3 high-speed machining tool path generation process throughout the experiment dimensional path of the tool offset of the boundary curve that appears when simulation can easily find the raw area .Calculating the intersection of the outer boundary curve of the offset curved surface and cutting CL- critics in tool, and using the calculated data, and generates a contour parallel to the tool path. The rough machining tool path generation method of surface proposed in this study is additionally performed using the path creation tools on the outside surface of curved cutting plane navigation.
