Model based prediction approach for internal machine tool heat sources on the level of subsystems

by Simon Züst, Adam Gontarz, Florentina Pavlicek, Josef Mayr and Konrad Wegener

Abstract

Modern machine tools are highly sophisticated mechatronic systems. Each subsystem’s energy efficiency is important regarding thermal effects of the machine: Losses in the subsystems are mainly heat sources, causing temperature gradients and thermal elongation. Knowledge about the internal heat sources is therefore mandatory for high precision machining, as well as for the design of compensation strategies. This paper presents a modeling approach to estimate the heat release of machine tool subsystems and predict boundary conditions for thermal models. The simulation results are verified by measurements on an internal cooling system of a lathe.
