Abstract
A six-axis CNC belt grinding machine automatic programming technology was studied in this paper, and which used D-H rule to solve out five-axis motion variables (the DOF of A, B, X, Y, Z), then discussed the problem of maximum contact degree between the grinding wheel and contact surface, and solved out the C-axis motion variable (the sixth DOF) by the direction of principal curvature in each cutter location point, after that gave a modified method of C-axis motion variable to smooth the machining. In order to ensure the machining accuracy while improving the machining efficiency, the paper summarized the self-adaptive spacing and step distance calculation method. The results which verified by a simulation analysis were validity and reliability, and provide a new thinking and beneficial reference for the research of other similar NC programming technology.
