摘要: In multi-axis CNC machining, a cutting tool combines translation and rotational movements with respect to workpiece. This entails interpolation take angular feedrates defining the speed of movement into account, while current interpolations are overwhelmingly based on linear movement. paper considers feedrate 2D paths for machining. A path is identified by position curve assumed be implicit orientation curve. The will relate along paths. result then used develop from interpolation. Detailed schemes such hybrid as constant constrained (CLCA) (CACL) have further been constructed. corrected scheme present augment initial Example including quadric curve, nodal cubic quartic carried out illustrate feasibility effectiveness proposed approach.
