Ball bar test for machine tools

Abstract

This paper deals with a problematic of machine tools and their precision. It is talking about Ball bar test of the machine tools. Paper deals with one measurement made in company Microstep on their machine tools. In this part are also presented results of the test and at the end is made conclusion from this result. In second part is describing measurement system from company Renishow for ball bar test. It is Measurement system QC10. It also describes the way of testing by this measuring system. In third part it describes different mistakes in kinematics and geometrics of machine tools. It also describe the way how the look at the graphical result of the test.
