| Abstract: | The multi-axial NC belt grinding cutter contact point optimization is one of difficulties in sculptured surface manufacture area.The objective function was proposed,which considered the cutter efficiency,path length and processing time.The error analysis were given,which considered those factor including wide-line processing,geometric characteristics of elasticitycutter,wear and tear of cutter in processing.A new adaptive algorithm was proposed,in which the tool path direction was decided by the min-curvature principle. |
| Keywords: | sculptured surface belt grinding cutter contact optimization |
