| Abstract: | The multi axis NC machine tool typically consists of two open kinematics chains: workpiece chain and cutter chain. According to this principle, the kinematics model and error model of multi axis NC machine tools have been analyzed and set up, and then a generalized algorithm for post processing of multi axis NC machine tools is presented in this paper. The algorithm can be used to generate the coordinated motion value for all types of multi axis NC machine with all sorts of errors according to the tool path generated by the CAM system. |
