Abstract

The embodiment of the invention discloses a multi-axis numerical control machine tool on-machine measurement data compensation method and system, and the method comprises the steps: measuring a reference coordinate point of a preset standard ball through a measuring head in a zero state of rotating shafts of all machine tools, and obtaining a first coordinate; rotating the rotating shaft to a rotating angle during on-machine measurement; measuring the reference coordinate point of the standard ball through a measuring head to obtain a second coordinate; and obtaining a compensation amount according to the first coordinate and the second coordinate so as to realize error compensation during on-machine measurement. The compensation amount is measured and calculated through the multiple rotating shafts and the preset standard ball, so that error compensation during on-machine measurement is achieved, and the technical problem that in the prior art, compensation is not provided for on-machine measurement of a workpiece, and consequently precision is not high is solved.

Description

technical field [0001] The invention relates to the field of on-machine measurement of numerically controlled machine tools, in particular to a method for compensating on-machine measurement data of a multi-axis numerically controlled machine tool and a system thereof. Background technique [0002] Multi-axis CNC machine tools, such as the more common five-axis CNC machine tools, have the advantage of being able to process parts with complex surfaces, avoiding multiple clamping of parts. Processing productivity. In order to meet the requirements of processing closed-loop control, intelligent processing, and processing quality control, on-machine measurement has become an essential function of five-axis machine tools. Different from the probe for measuring machine, the probe for on-machine is a fixed probe, which cannot be rotated by itself. With the help of the rotation of the two rotating axes of the five-axis machine tool, the probe can be angled relative to the workpiece...
