Abstract

A new measuring device for volumetric measurement of machine tools developed at the Department of Production Engineering at the Technical University Graz integrates static and dynamic test principles in a single instrument. Linear positioning test, circular test and freeform test can be applied to unconventional machine structures like industrial robots and hexapods, measuring simultaneously position and orientation of the machine tool's end effector during the motion. 1 Introduction The development of industrial robots and, in particular, of hexapods with their potential in high speed cutting has made rapid progress. Due to the need of attaining reasonable accuracy even at elevated speeds, dynamic measurement is gai
