A Computable and Reconfigurable Machine Tool Geometric Pose Error Definition Method

Abstract

The invention discloses a computationally reconfigurable geometric pose error definition method of a machine tool. In this method, a reconfigurable machine tool configuration tree model is firstly established, and the general expression of the geometric pose error and the pose error definition coefficient matrix of the linear axis motion module and the rotary axis motion module are defined. Then, on the basis of the configuration tree model, the definition sequence of the geometric pose error of the linear axis and the module type of phase mapping are determined, the definition operator of the geometric pose error of the linear axis is designed, and the coefficient matrix of the linear axis' pose error definition is calculated. Then, the geometric pose error definition operator of the rotation axis is designed to determine the definition coefficient matrix of the rotation axis pose error according to the type of the rotation axis. Finally, the definition of the geometric pose error of the reconfigurable machine tool is realized by adapting the calculation coefficient matrix. The present invention can realize the intelligent definition of the geometric position and posture error of the reconfigurable machine tool through the programming calculation method, so as to adapt to the constantly changing structural configuration of the machine tool and reduce the experience requirements of operators.
