Method of load characteristic identification and acceleration adjustment for machine tool

A method of load characteristic identification and acceleration adjustment for a machine tool, suitable for applying in the machine tool, wherein the machine tool comprises a transmission system and a working platform, the method comprising:

• setting a first acceleration of the transmission system according to a weight of a workpiece, and driving the working platform and the workpiece at the first acceleration;
• calculating, according to the weight of the workpiece, an amount of first elastic deformation of the transmission system when the transmission system moves at the first acceleration;
• calculating, according to a feedback position signal of the transmission system, an amount of first position error of the transmission system when the transmission system moves at the first acceleration;
• calculating a dynamic error according to the amount of first elastic deformation and the amount of first position error, and determining whether the dynamic error is equal to a target error, and setting a second acceleration to the transmission system when the dynamic error is less than or greater than the target error, and calculating an amount of second elastic deformation and an amount of second position error of the transmission system when the transmission system moves at the second acceleration until the dynamic error is converged to the target error.
