Abstract

The invention relates to a multi-axis servo matching method and device for an AC type double-swing-head five-axis linkage machine tool. The method comprises the following steps: planning a space trajectory in which multiple axes participate in motion at the same time in an RTCP function opening state; selecting a certain single axis from the plurality of single axes in the low dynamic response state as a matching object; combining the other single axes in the low dynamic response state and the matching object into matching combinations, wherein for each matching combination, roundness test servo matching means that servo system parameters of the matching object are kept unchanged; changing servo system parameters of the other single axis in the matching combination, carrying out operation according to a set circular track, and determining servo system parameters of the other single axis by combining an optimization algorithm with evaluation indexes; and operating the parameters in the space trajectory, judging whether the requirements are met or not through a second dynamic precision evaluation index, if the requirements are not met, continuing to carry out roundness test servo matching, and if the requirements are met, stopping matching. The machining precision of the system is improved by matching each single axis parameter.

Description

technical field [0001] The invention relates to an AC-type double swing head five-axis linkage machine tool multi-axis servo matching method and device, belonging to the technical field of five-axis linkage machine tool servo control. Background technique [0002] As the five-axis linkage machine tool combined with high-speed rotating shafts has become more and more widely used in high-precision complex curve processing in recent years, the dynamic accuracy and overall dynamic performance of the cutter head have also become the focus of scientific research workers at home and abroad. One of the research hotspots. At present, the research on the servo feed system of five-axis linkage machine tools basically focuses on the causes of tracking errors caused by each single-axis servo feed system and its impact on the final machining accuracy. However, the research on the impact of precision is very scarce. Servo matching refers to the optimization and adjustment of the linkage ...
