加工中心的加工精度一方面由机床的几何精度和数控精度保证,另一方面与工件坐标系坐标值的测定有很大关系。因此,如何快速准确地测定工件坐标系坐标值是加工中心应用中的一个重要问题。 目前,我国应用的卧式加工中心有相当一部分没有自动测定坐标系功能,在这类机床中,建立工件 Machining center machining accuracy on the one hand by the geometric accuracy of the machine and CNC accuracy assurance, on the other hand with the workpiece coordinate system coordinate values ​​have a great relationship. Therefore, how to quickly and accurately determine the coordinates of the workpiece coordinate system machining center is an important issue in the application. At present, a considerable part of the horizontal machining center applied in our country does not automatically determine the coordinate system function. In such a machine tool, a workpiece
