【Abstract】 Spatial cams are important control parts used widely in automatic mechanisms. Because of their special contours, it is very difficult to finish NC programming for these parts by common CAD/CAM software. Therefore, an effective CAM technology for spatial cams is presented, which can solve most of spatial cams’ NC programming problem. With this technology, the spatial curve NC programming issue is converted to a planar curve NC programming. Using this CAM technology, several kinds of spatial cams are programmed and machined, and the applications show that this CAM technology is feasible and reliable.更多还原
