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.
