Abstract

This paper describes tests that have been performed on 10 different CNC machine tools of widely differing configurations. These tests aim to identify thermal errors and methods by which these errors may be eliminated from components produced by these machines. The paper consists of three sections which describe the general testing methodology used, the data recorded and analysed from the tests, and a list of actions which may be performed in order to reduce the thermal errors in the machines tested. The general testing methodology has evolved from both the BSI 3800 part 3 standard and the need to identify the factors affecting thermal errors. Thermal imaging, non-co
