Abstract

The invention relates to five-axis laser devices, in particular to an RTCP calibration device and method for a five-axis laser device. The RTCP calibration device and method for the five-axis laser device solve the technical problem that it is difficult to perform RTCP calibration by an existing five-axis laser device. The RTCP calibration device comprises a base, a rotating table, a pitching adjusting device, an axial adjusting device, a CCD detector and a controller; the rotating table is arranged on the base, and the rotation axis of the rotating table is horizontally arranged; the CCD detector is arranged on the axial adjusting device, the axial adjusting device is arranged on the pitching adjusting device, and the pitching adjusting device is arranged on the rotating table; or, the CCD detector is arranged on the pitching adjusting device, the pitching adjusting device is arranged on the axial adjusting device, and the axial adjusting device is arranged on the rotating table; andthe controller controls the rotating table to rotate according to a motion program of the five-axis laser device and calculates RTCP parameters and an offset of the five-axis laser device according toinformation fed back by the CCD detector. The RTCP calibration method is carried out by using the RTCP calibration device.

Description

technical field [0001] The invention relates to calibration equipment, in particular to a five-axis laser equipment RTCP calibration equipment and method. Background technique [0002] RTCP (English name is Rotational Tool Center Point, which can be translated as rotary tool center programming) is the CNC system programming for five-axis machine tools to realize the tool center management function, and it is also the only criterion for judging whether a five-axis machine tool is a true five-axis or a false five-axis . The five axes in the five-axis machine tool are used to cooperatively control the position of the center point of the tool in the machine tool, so that the actual machining point of the tool falls on the actual contact point between the tool and the surface of the workpiece. Here the five axes, such as figure 1 As shown, it specifically includes a three-dimensional Cartesian coordinate system composed of three mutually perpendicular linear axes X, Y, and Z, a...
