Embodiment Construction

[0019] A measurement method for five-axis machine tools based on AxiSet. The main process includes: establishing the kinematics model and error model of the five-axis machine tool, and determining the four structural errors of the five-axis machine tool, that is, the axial error of the two rotating axes and the relationship between the two The position offset error from the tool coordinate system related to the rotary axis to the rotary axis; determine the measurement scheme: set AxiSet TM The Check-up component is installed on the CNC machine tool, and the center of the standard ball is calibrated by the trigger probe; according to the machine tool error model, the four structural errors of the five-axis machine tool are calculated; the calculated four structural errors are substituted into the kinematics model In the process, the kinematics model is corrected to realize the error compensation of the five-axis machine tool.

Abstract

The invention belongs to the technical field of numerical control, and particularly provides the design of a five-axis machine tool measuring method based on AxiSet. The method includes the steps that according to kinetic models of five-axis machine tools, the influence of structural errors of the five-axis machine tools on cutter location points is determined, and a five-axis machine tool kinetic error model is set up; the error model is analyzed, so that the sources of error terms of the machine tools are determined; the characteristics of the models of the three types of machine tools are analyzed, and measuring schemes for the machine tools are determined; according to hardware equipment adopting an AxiSet<TM> Check-up assembly, a touch trigger probe is used for collecting data of a master ball; and the collected data are substituted into the error models, and after the error terms are worked out, the kinetic models of the machine tools are corrected. By means of the five-axis machine tool measuring method, machining precision of an existing numerically controlled machine tool can be improved, and measurement bases are provided for measurement of multi-axis machine tools in the future.

Description

technical field [0001] The invention belongs to the technical field of numerical control, in particular to an AxiSet-based five-axis machine tool measurement method. Background technique [0002] As we all know, there are initial machine tool errors in the process of machine tool assembly and manufacturing, and the long-term and high-load operation of the machine tool will cause wear and tear on the relevant parts of the machine tool, resulting in a certain deviation between the actual parameters and the theoretical parameters. Specifically reflected in kinematics, there is a certain translation error and rotation error in the machine tool, which makes the rotation axis and the spindle deviate from the original position, thus affecting the accuracy of the workpiece when using the machine tool for processing. [0003] Many devices can be used to measure the structural errors of 5-axis machine tools, such as dial indicators and test rods, double ball bars, etc. Dial indicator...
