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.

Abstract: A cutting tool controller and method of controlling are provided. The method includes providing a swing angle for the cutting tool, obtaining a swing vector of the cutting tool through kinematics calculation according to the swing angle, using the swing vector of the cutting tool to calculate a set of possible solutions of a swaying angle of the cutting tool, selecting a possible solution satisfying an operation condition of the machine from the set of possible solutions, using the selected possible solution to calculate an offset of positions of the cutting tool before and after swaying, so as to generate a compensation vector, calculating required compensation values for three axes of the machine according to the compensation vector, and outputting a control command including the compensation values, such that the cutting tool of the machine or a working table for placing the workpiece thereon of the machine moves correspondingly.
