| Abstract: | This paper presents a general model of geometric errors for CNC machine tools,based on the analysis and synthesis of spatial mechanism as well as homogeneous transformation used in the kinematics of robotic motion. The validity of the model is experimentally confirmed on a vertical spindle-machining center. The model and conclusion can be applied to the modeling and compensating of errors of multi-axis CNC machine tools. |
