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 machining assistance method and an apparatus using the same are provided. The machining assistance method comprises following steps. Firstly, a circle correction path is received for driving a platform to perform a circular motion. Next, a driving torque of the server driver driving the platform is obtained. Then, whether the driving torque is changed to 0 is determined; if yes, a first position of the platform is recorded. Then, whether the driving torque is changed to a peak is determined; if yes, a second position of the platform is recorded. After that, the server driver is controlled to drive the platform according to a first position and a second position in a machining process.
