Abstract

The invention discloses a method for checking the accuracy of the swing angle of a numerical control machine tool, which belongs to the technical field of numerical control processing, and is characterized in that it comprises the following steps: a. installation; The X-axis of the machine tool coordinate system is parallel, so that the top plane M5 is parallel to the XY plane of the machine tool coordinate system; c, fixing; d, alignment, find out the Z coordinate value of the top plane M5 in the machine tool coordinate system, and establish the coordinate system; e , vertical and horizontal conversion; f, secondary alignment; g, compare the measured values ​​of the coordinates of the reference hole K2 and the reference surface M2 with the theoretical values; h, compensate the deviation values ​​ΔX, ΔY and ΔZ into the corresponding processing coordinate system, And perform step f for review. The invention is suitable for the detection and accuracy compensation of the positioning error after the vertical-horizontal conversion of the spindle swing angle of the five-coordinate numerical control milling machine or the replacement of multiple spindles, can compensate in real time, and meets the precision requirements of multi-faceted machining of complex workpieces.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to a method for checking the swing angle accuracy of a numerical control machine tool. Background technique [0002] With the development of aircraft design technology, the structural complexity and manufacturing precision requirements of aircraft parts are getting higher and higher; parts often have complex structures such as holes, grooves, ribs and lugs at the same time, which require the use of CNC milling machines for multi-faceted precise manufacturing. In order to ensure the size and position accuracy of the parts, a large number of one-time clamping and multi-face machining solutions are used to manufacture parts. Since the AC swing angle CNC machine tool has the rotation axis C along the spindle center and the swing angle axis A that makes a fan-shaped swing angle along the spindle rotation center, it can realize the processing of any vector within the t...
