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.

Key words: mechanism, error compensation, numerical control machine tool, numerical control program, post-processing
