Abstract :
CNC simulation will improve the efficiency of CNC machine tools and ensure the correction of NC code. It is difficult to promote the application of simulation algorithm to specific machine tools. This paper proposes a general description of CNC machine tools kinematic chain. NC code can be checked by workpiece coordinate system simulation effectively; hence a general conversion algorithm from machine coordinate system to workpiece is discussed. CNC machine tools models are built by OpenGL kernel to verify motion and workpiece simulation. The simulation results show that this description is correct and can be applied to any form of multi-axis cascade CNC machine tools.
