Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] It should be noted that when a component is said to be “fixed” to another component, it may be directly on the other component or there may be another intermediate component through which it is fixed. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be another intermediate component at the same time. When a component is said to be "set on" another component, it may be set d...

Abstract

The invention discloses a method for measuring a five-axis gantry swing head space axis error value. By means of the steps of cutting preparation, cutting requirement setting, cutting according to setcutting requirements, data analysis and recording, qualification determination, etc., the five-axis gantry swing head space axis error value can be measured, it is directly verified whether a bias value measured by an electric or mechanical method is correct, and correction is performed to quickly test the mutual relationship of axis C and axis A on a five-axis head and the axis of a main shaft and the actual swing length of the main shaft, so that the electric compensation value is more precise, and the processing precision of the five-axis head is improved.

Description

technical field [0001] The invention relates to a numerical control machining center, in particular to a method for measuring a space axis error value of a five-axis gantry swing head. Background technique [0002] Compared with three-axis machine tools, five-axis machine tools can process various complex surfaces, with higher production efficiency, better flexibility and less clamping time. However, the two rotation axes introduce more geometric errors, such as the position error and parallelism error of the axis of the rotation axis, etc., resulting in a larger spatial error for the five-axis machine tool. By measuring the error value of the space axis of the five-axis gantry swing head, and then compensating the space error of the machine tool, the overall accuracy of the machine tool can be improved. [0003] The existing measurement methods for the spatial axis error value of the five-axis gantry swing head mainly include mechanical methods and electrical measurement m...
