Research on Analyse and Compensation Approach Aimed at CNC Machine Geometrical and Kinematic Errors
The geometrical error and kinematic error are regarded as the prime reasons to bring about CNC machine contour error, which confine the improvement of machining precision further. In the paper, the main error sources that produce geometrical error and kinematic error in CNC machine are researched in detail, and an analyse approach aimed at the main error sources is put forward which adopts the arc interpolation motion - arc image method. Furthermore, the compensation approach aimed at error resources such as the mismatch of position loop servo gains and orthogonal axes out of the vertical is developed in CNC software. Finally, the analyse and compensation approach is tested on a CNC experiment table. The experimentation result reveals that the developed analyse and compensation approach aimed at the main error sources can enhance machine contour precision greatly. Consequently, the research is helpful to improve and keep CNC machine high precision longtime.
