Abstract

The embodiment of the present invention relates to the technical field of numerical control, and discloses a method for calibrating RTCP parameters of a five-axis linkage machine tool. , so that the ball at the end of the stylus coincides with the axis of the spindle; the machine tool returns to zero, the machine tool coordinates are cleared, and the measurement point corresponding to the first rotation axis and the measurement point corresponding to the second rotation axis are set; the stylus is driven by the programming control numerical control system Move to each measurement point along the set direction, and latch the coordinates of the 4 collision points corresponding to each measurement point; For the RTCP parameters in the machine tool coordinate system, the embodiment of the present invention has good versatility and is suitable for various types of five-axis machine tools; no expensive auxiliary calibration equipment is required, which is more efficient and low-cost; the calibrated RTCP parameters have high stability. sex.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of numerical control, in particular to a method for calibrating RTCP parameters of a five-axis linkage machine tool. Background technique [0002] The Rotation Tool Center Point (RTCP) function is a very important function of the five-axis linkage machine tool. The RTCP function greatly improves the NC machining code and programming efficiency. The RTCP function can convert the programming instructions based on the workpiece coordinate system into the motion instructions of the five motion axes under the machine tool coordinate system through kinematic transformation. Users do not need to pay attention to the complex motion of the five motion axes when programming. RTCP parameters are necessary parameters for motion transformation, and the accuracy of RTCP parameter calibration directly affects the accuracy of tool nose trajectory control. [0003] At present, foreign high-end five...
