| Abstract: | An effective algorithm is presented here for seeking and realizing the intersection of tool sweep volume with surface vector. The intersection of sweep volume with complicated surface normal is transformed into computation of intersection between triangular mesh and directed line segment. The efficiency of algorithm is enhanced by setting up intersection subset of these two in the previous algorithm. An example is given here to show the application of this algorithm to the complicated surface machining of impeller vanes as a whole. |
