FIVE-AXIS LINKAGE NUMERICAL CONTROL MACHINE TOOL ROTATION AXIS POSITION ERROR DETECTION METHOD AND DEVICE

摘要

A machine tool rotation axis position error detection device, comprising a support (11) and three displacement sensors (12). The three displacement sensors (12) are separately mounted on the support (11); a direction line (13) of a third displacement sensor (12) passes through the intersection point (14) of direction lines (13) of the first two displacement sensors (12), and is located outside the plane defined by the direction lines (13) of the first two displacement sensors (12). The present invention aims at solving the problem in the prior art of complex use and long detection time during machine tool rotation axis error detection, and can conveniently and quickly implement rotation axis error detection. Also provided are a machine tool rotation axis position error detection method and a five-axis linkage numerical control machine tool rotation axis position error detection method.
