Fletcher, Simon, Mian, N S and Longstaff, Andrew P. (2014) Optimising temperature sensor placement for machine tool thermal error compensation. In: EUSPEN Special Interest Group: Thermal Issues, 19-20 March 2014, Novotel Zurich City, Zurich, Switzerland. (Unpublished)

In this article, results of thermal error assessments are evaluated from a range of modern machine tools operating with active thermal compensation. The standard models assume a linear relationship between temperature and displacement and implementations address only a limited subset of error sources. However, significant residual errors were found on the analysed machines. The aim of this work is to improve the accuracy and increase the scope of compensated errors, without introducing onerous complexity, by using optimised linear correlation models applied to existing controllers.
