Abstract
An error compensation method for multi-axis parallel kinematics machine tools, including: building a theoretical Jacobian model of a multi-axis parallel machine tool to be compensated; and obtaining several geometric parameters of the theoretical Jacobian model and constructing a singularized geometric error model; constructing a singularized geometric error model with modeling error; solving the singularized geometric error model to obtain a singularized geometric error; substituting the singularized geometric error into the theoretical Jacobian model to construct a Jacobian model with correction term; generating a correction value of a motor of the multi-axis parallel machine tool to be compensated; calculating a corrected total displacement of the motor; substituting the corrected total displacement into an error prediction evaluation model to calculate predicted compensation errors under different geometric parameters; selecting a minimum predicted compensation error as a target compensation error. Thus improving the accuracy of error compensation for multi-axis parallel kinematics machine tools.
