Abstract:
Aiming at high speed machining, two new algorithms of 5-axis tool-path generation for flank machining and global checking on tool-path collision are put forward. The first algorithm, relying on quantic NURBS(non-uniform rational B-spline)rule-face fitting any other original face, generates C2-continuous CL(cutter location)-curve and even changed tool-axis vector. The second algorithm, depending on setting the threshold controlling tool-axis vector and using solid based on Boolean-operation, realizes unsafe CL-points and Boolean-operation check. The algorithms have been applied to Superman CAMⅡ prototype system, and the test results show that the algorithm of tool-path generation runs nearly as fast as that of UG software, and can acquire Ra 0.8 μm surface-quality in milling blades of impeller. The algorithm of checking on tool-path collision can rapidly detect cut-collision and figure out the gouged size.
