Post-processing optimization algorithm for blade six-axis NC machining

Abstract In order to solve the problem of fluctuation in the six-axis NC polishing machining, in this paper, a post-processing optimization algorithm for six-axis NC polishing machining is proposed, which can solve the problem of fluctuation in the machining process of six-axis NC machining. First, the initial A-axis angle value corresponding to the tool position is solved according to the tool position information contained in the toolpath file; Second, use B-spline to smooth the data of A-axis, and solve the corresponding B-axis and C-axis angle value according to the angle value of A-axis; Third, calculate the moving value of X-axis Y-axis and Z-axis to realize the post-processing of the toolpath file; Finally, the algorithm is verified that it can solve the machine trajectory fluctuation in the current six-axis post-processing using VERICUT and the machining experiments, and realize the high quality six-axis NC polishing machining.
