Abstract

The invention relates to the field of calibration of coordinate measuring machines, in particular to a method for calibrating comprehensive errors of a five-coordinate measuring machine. The method aims to meet the requirement that a calibration mode is consistent with an actual detection mode, correctly analyze the influence of five-axis comprehensive errors on detection parts, and meet the requirement of traceability of values. Space five-axis comprehensive error calibration is achieved by reasonably establishing a coordinate system, designing and determining calibration space theory positions and formulating a calibration path. On the basis of a comprehensive accuracy calibration technology of a four-axis coordinate measuring machine, a scheme and steps of comprehensive accuracy calibration of the five-axis (two rotation axes and three coordinate axes) measuring machine are developed and designed, the appropriate coordinate system, the calibration scheme and the calibration path are designed and established, the actual detection of theoretical positions is achieved by determining the theoretical positions of the center of a standard detection sphere in measurement space, comprehensive error values of the five-coordinate measuring machine are obtained through the comparison of theoretical values with measured values, and the requirement that the calibration mode is consistent with the actual detection mode is met.

Description

technical field [0001] The invention relates to the field of calibration of coordinate measuring machines, in particular to a comprehensive error calibration method for five-coordinate measuring machines. Background technique [0002] In order to meet the development needs of production, scientific research and measurement technology, the comprehensive precision calibration of five-coordinate measuring machines has become an urgent calibration technical problem to be solved. According to the requirements of JJF1064-2010 Coordinate Measuring Machine Calibration Specifications, comprehensive calibration accuracy calibration should be carried out for multi-axis measuring machines. The comprehensive errors of four linear coordinate axes are calibrated, and the specific operation method of four-axis error calibration is stipulated, and the methods and steps of how to establish a coordinate system, construct an ideal space position, coordinate conversion and actual detection are d...
