Embodiment Construction

[0071] The present invention will be further described in detail below in conjunction with the accompanying drawings. The given embodiments are only used to illustrate specific implementation and beneficial effects, and are not intended to limit the protection scope of the present invention.

[0072] Such as figure 1 As shown, a method for error compensation of the rotary axis of a double turntable five-axis linkage machine tool, which includes the following steps:

[0073] (1) Set tool length and current coordinate system:

[0074] Use a tool setting instrument to measure the value of "knife handle length + length of small ball adsorption rod + standard small ball radius", set the length of T1 knife as this value, and use T1 knife when detecting errors.

[0075] According to the machine tool assembly relationship (RTCP parameter), set the X, Y, and Z values ​​of the current coordinate system (such as G58) to the values ​​of the C-axis rotation center in the A-axis coordinate...

Abstract

The invention provides an error compensation method for the rotation axis of a double turntable five-axis linkage machine tool, which includes the following steps: setting the tool length and the current coordinate system; installing the measuring center seat at the end of the workbench, measuring and calculating the installation error; establishing the installation error and The error model of the rotary axis including the assembly relationship of the machine tool; through this error model, the 12 error values ​​generated when the two rotary axes rotate are calculated; the error compensation of the rotary axis and the linear axis is decoupled, and the error compensation value is corrected; the numerical control is corrected according to the error compensation value The code realizes the error compensation of the rotary axis of the double turntable five-axis linkage machine tool. The invention has high versatility, improves the accuracy of the error model, and realizes the automatic and efficient error detection of the five-axis machine tool.

Description

technical field [0001] The invention relates to an error compensation method of a numerical control system of a numerical control machine tool, and more particularly relates to an error compensation method of a rotation axis of a double turntable five-axis linkage machine tool. Background technique [0002] The five-axis CNC machine tool has the ability to move and rotate the tool or workpiece at the same time, and can process free-form surfaces with complex geometric shapes and high precision requirements, which plays a major role in the current manufacturing industry, especially the military industry. At present, the measurement of the rotation axis error mainly adopts the indirect measurement by installing the standard rod and the standard ball. This method will introduce the contour error of the standard rod and the installation and centering error of the chuck, etc., and reduce the compensation effect of the rotation axis error. Renishaw proposed the XR20-W wireless rot...
