摘要： 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.

摘要： Firstly, a robotic arm drives a projection point of tool projected on test plane to perform relative movement relative to a reference point of a test plane. Then, conversion relationship is established according to the relative movement. Then, a tool axis vector relative to an installation surface reference coordinate system of the robotic arm is obtained. Then, calibration point information group obtaining step is performed, wherein the calibration point information group obtaining step includes: (a1) the robotic arm drives a tool center point to coincide with a reference point of the test plane and records calibration point information group; (a2) the robotic arm drives the tool to change angle of the tool; and (a3) steps (a1) and (a2) are repeated to obtain several calibration point information groups. Then, tool center point coordinate relative to the installation surface reference coordinate system is obtained according to the calibration point information groups.

摘要： A goal-oriented numerical control automatic tuning system is used for a numerical controller of a machine tool to automatically tune the machine tool. The system includes a goal-oriented input module for receiving external goal values; a machining test path selecting module for receiving an external machining path; and an automatic machine-tuning equation module including a control equation with a predetermined equation coefficient for receiving the goal values and the machining path from the goal-oriented input module and the machining test path selecting module, respectively, such that an appropriate control parameter can be obtained by calculating the control equation based on the goal values and the machining path, and then this control parameter passed to a numerical controller in order to control actuation of the machine tool.
