Abstract

Traditional CAM algorithms evaluate the cutting error only based on the geometry of the sculptured surfaces. The kinematic parameters, such as rotational angles, machine structure, and tool geometry, are not considered until the post-processing stage. When using the tool paths generated by traditional algorithms, the corresponding cutting errors may be larger than expected due to rotation. Therefore, the estimation algorithm presented in this paper considers not only surface geometry but also kinematic parameters. Compared to traditional CAM algorithms, simulation results show that the step lengths are varied adaptively, and cutting errors are reduced.
