加工中心在线检测系统误差补偿技术研究

Research on the software error compensation in machining center on-line inspecting system

基于多体理论,建立了加工中心在线检测系统的几何误差与热误差综合模型,对测头误差处理技术进行了研究,利用该模型可以同时对测头误差、机床几何误差与热误差进行补偿,实验表明,此方法有效地提高了在线检测精度。

The modeling errors are investigatod, based on the software error compensation in machining centers on-line inspecting system. The method can compensate probe errors, thermal and geometric errors.The experiment shows that the accuracy of the inspeting is improved effectively.
