摘要（英）：

The invention discloses a machine tool displacement compensation method and system based on calibration volume. The machine tool displacement compensation method based on calibration volume includes the steps: acquiring the displacement of the kinematic axis when the kinematic axis has different volumes during the working process of the machine tool, and establishing a function mapping relation between the kinematic axis volume and the displacement; respectively obtaining the kinematic axis volume during the working process of the machine tool at the working time, t1, t2,.., tn, recording the kinematic axis volume as v1, v2,..., vn, and establishing a kinematic axis working time and volume reckoning table; obtaining the current working time ti of the kinematic axis, and according to the ti, searching for the reckoned volume vi of the kinematic axis from the kinematic axis working time and volume reckoning table; acquiring the measured volume vi' of the kinematic axis at the working time ti, comparing the reckoned volume vi of the kinematic axis with the measured volume vi', and according to the comparison result, obtaining the calibration volume v of the kinematic axis; and according to the calibration volume v of the kinematic axis and the function mapping relation between the kinematic axis volume and the displacement, obtaining the target displacement of the kinematic axis to compensate the kinematic axis.
