摘要
采用曲面分片思想将具有相同或相似曲面信息与工艺特征的复杂曲面分成曲面片族,利用环形刀在各曲片域内建立等残留高度刀具路径规划策略,使刀具姿态随工件曲面的曲率而变化,并完成曲面片间的光顺接合。该方法可从整体上提高复杂曲面的加工精度,改善曲面加工质量。
Fragmentation method is applied to Subdivide complex curved surface with the same or similar characteristics of the surface pieces,the tool path planning generation on iso-scallop is established in various surface pieces domain by torus end-mill ,tool-pose changes along with the curvature of machining surface .According to this method,smooth integration is completed between the surface pieces,which leads to the improvement of machining quality as well as the prevention of interference between work piece and too1.
