Abstract

Aims at AOCMT type five-axis ultra-precision CNC machine tool, the rotary axis geometric errors model is established by applying the homogeneous coordinate transformation matrix, a kind of errors measurement and identification method is put forward. It takes A axis as an example, using the function of RTCP to control a rotary axis and two translational axes synchronous movement. Different height and positions are designed, and the modes of the measurement are the axial, radial and tangential. The length variations are acquired, and the relational expressions of deviations and length variations are derived according to the errors model. Eight deviations related to A axis can be identified at the same time. The method is available through the simulation.
