Abstract: A new generation algorithm of tool swept volume is introduced. Through partitioning points outside moving object into ingress points, egress points and grazing points, the new algorithm can quickly find all grazing points to generate swept volume, so not depend upon the theory of envelopes of formerly generating swept volume, avoid solving complex equations. So it possesses many advantages of simple process, easy programming and quick operation etc. Although this algorithm is developed for tool swept volume, it is suitable for generating swept volume of any rotation solid.
