Abstract: A method of load characteristic identification and acceleration adjustment for a machine tool is provided. A first acceleration of a transmission system is set according to the weight of a workpiece, and the working platform and the workpiece are driven at the first acceleration. A first elastic deformation of the transmission system and an amount of first position error of the transmission system are calculated when transmission system is moved at the first acceleration. A dynamic error is calculated according to the first elastic deformation and the first position error. When the dynamic error is less than or greater than a target error, a second acceleration is set to the transmission system, and a second elastic deformation and a second position error are calculated when the transmission system moves at the second acceleration unit the dynamic error is converged to the target error.

Abstract: A method for facilitating analysis of causes of machining defects is provided. The method is carried out by a computer system. The method includes the step of obtaining motion data and vibration acceleration data about the tip of a cutter mounted on a machine tool. The method further includes the step of obtaining time-frequency information about the vibration acceleration data by performing a time-frequency analysis on the vibration acceleration data. The method further includes the step of obtaining vibration-displacement data by normalizing the time-frequency information. The method further includes the step of obtaining amplitude-distribution data about the tip by synchronizing the motion data and the vibration-displacement data.
