Abstract: A backlash automatic detection system comprises a control device and a machine tool. The machine tool comprises a servo driver, a lead screw, a nut seat and a platform. The method comprises: entering an initial state and outputting a control command to the servo driver through the control device; driving the lead screw by the servo driver to move the nut seat towards a first direction and changing the movement direction of the nut seat towards a reverse second direction by the servo driver; defining a backlash phenomenon period according to one time point at which the nut seat starts to move towards the second direction and another time point at which the platform is driven to move by the nut seat; defining the displacement of the nut seat corresponding to the backlash phenomenon period as a backlash value.

Abstract: A detection device, detection method, and compensation method for tool wear, applied to a machine tool including a spindle connected to a tool. A first parameter set including a first cutting depth having a zero cutting depth is set, and the machine tool performs a cutting procedure with the first parameter set to record a first loading rate of the spindle. A second parameter set including a second cutting depth having a non-zero cutting depth is set, and the machine tool performs the cutting procedure with the second parameter set to record a second loading rate of the spindle. A processing device calculates an estimated cutting force according to the loading rates and a machine performance database. A fuzzy logic unit outputs a wear level according to a tool wear database and the estimated cutting force. The machine tool adjusts a cutting locus according to the wear level.
