Abstract
Reliable production processes require an identical behaviour of identical machine tools. In the course of this paper a measuring method to estimate the variation of behaviour of feed axes by friction is conducted at machine tools in serial production. Thereby severe variances of friction are detected, which are caused by assembly variances. The reasons of these variances are examined by variation of assembly conditions of a test stand and verified by simulation. A modelling approach for simulating assembly variances reliably has been developed.
