Method of determining geometric parameters of a CNC milling machine

摘要

In order to determine geometric parameters xsp, xsr of a CNC milling machine, the milling machine is used to carry out a measurement movement, the respective distances rm of a mill point P' from the workpiece zero point Wo as the measurement movement is carried out being measured. Subsequently, the measured distances rm are compared with the distances r of the mill point P' from the workpiece zero point Wo calculated from the NC position values for the axes x, y, z, 4, 5 of the milling machine, these calculated distances r being a function of the geometric parameters xsp, xsr to be determined. For the geometric parameters xsp, xsr, the values are determined which lead to the smallest deviation between the measured distances rm and the calculated distances r. IMAGE
