Abstract

This paper is about the static error measuring strategy of five-axis CNC machine tool basing on the touch-trigger probe, which is the mainly measuring tool to detect the static error of the five-axis machine tool of RTTTR and RRTTT topological structure. According to kinematic chain of the five-axis NC machine, the relationship between NC machine coordinate system and workpiece coordinate system is established and the relationship between NC machine coordinate system and tool coordinate system. Now the measurement and identification of three axis NC machine tool has been studied a lot, which means that the error of straight line can be measure and compensate very well. So in this paper we assume that the error of the translation axis has been compensated and the motion error of the rotation axis is small enough relative to the static error. Then based on the relationship between static error and the actual coordinate values in the model established before, the static error of each rotation axis can be solved.
