Geometric errors measurement of a large scale five-axis gantry type high speed machine tool

Abstract

With the requirement of higher productivity and increased automation, precision five-axis machine tools are essential element of an industrial society. So enhancing the accuracy is become increasingly important on five-axis machine tool. The position dependent systematic geometric errors are 30 and the position independent systematic errors are 9 in a five-axis machine tool. It is necessary to measure all these errors components precisely in order to utilize software error compensation for accuracy improvement. A laser interferometer system and DBB test system have been built for a five-axis machine tool geometrical error measurement in this paper. © 2011 Springer-Verlag.
