A single-time alignment control method for multi-face machining of clutch housing based on kinematic modeling

To address the problem of repeated manual alignment in the multi-angle surface machining of clutch housings, a single-alignment control method based on kinematics modeling for non-RTCP (Rotational Tool Center Point) machine tools is proposed. Unlike traditional processes that require manual re-alignment after each A-axis rotation, the proposed method first establishes and solves the machine tool kinematic model to derive accurate machining coordinate transformation formulas. A dedicated digital machine model is constructed, motion logic between kinematic axes is optimized, and an interactive interface between the machine tool and CAM (Computer Aided Manufacturing) software is developed. CNC (Computer Numerical Control) system macro-program secondary development is implemented for customized machining safety control, and a specialized post-processor is built by extracting key machining parameters. Tool paths are post-processed in CAM software, and generated NC (Numerical Control) programs are verified via simulation and actual machining. The results show that the method eliminates repeated manual alignment entirely, reduces setup time and human-induced errors, and adapts perfectly to non-standard modified machine tools, providing a practical and efficient solution for multi-face machining of clutch housings.
