Abstract

The invention discloses a five-axis RTCP (Rotation Tool Centre Point) measurement method. The method includes the following steps that: the plane coordinate value of a rotation center of a worktable in a machine tool coordinate system is measured; the swing length of a distance from the swing head of a machine tool to the end surface of a main shaft is measured, wherein the swing head of the machine tool is used for clamping a cutter; the deviation value of the swing head relative to the worktable after the swing head swings in a range from -90 degrees to +90 degrees is measured; and the abovemeasured parameters are inputted into a system to verify whether RTCP functions and parameter settings are correct. Since the related parameters of an RTCP are measured twice successively; the related parameters are inputted into the system; the RTCP operates, so that whether the RTCP functions and parameter settings are correct can be accurately and effectively verified; and therefore, a good verification method can be provided for RTCP function adjustment and parameter setting, the fast and accurate setting of the RTCP can be realized, the machining accuracy of the machine tool can be improved. The RTCP functions are realized through simple and easy-to-operate data measurement, and five-axis programming processing can be simplified.

Description

technical field [0001] The invention relates to a machine tool system measurement method, in particular to a five-axis RTCP measurement method. Background technique [0002] The RTCP (Rotation Tool Center Point) function is a commonly used function in the five-axis system. The five-axis system will keep the tool center at the programmed XYZ position. In order to maintain this position, every movement of the rotational coordinates is compensated by a linear displacement of the XYZ coordinates, always keeping the tool center at the same position. In this case, the path of the tool center can be programmed directly without taking the center of the rotary axis into account. The axis center is independent of the programming, it is input by the display terminal before executing the program, and has nothing to do with the program. Therefore, the five-axis programming and machining of the system with RTCP function are much simpler and more complicated. Contents of the invention...
