Traditional CAM packages generate five-axis machining codes (G and M codes), which depend only on surface geometric information. When applying these codes to different five-axis CNC machines, the corresponding cutting errors sometimes are larger than the expected values. This is because the cutting errors depend on the machining conduction parameters such as the cutter geometry, rotational axes, etc. This paper is to introduce a machine codes modification algorithm for those generated from existing CAM packages so that the final cutting errors of modified codes are within the tolerance requirement. Simulation and experiments have been conducted to verify the modified machine codes and the results turn out to be successful.
