Study on Temperature Control of Machine Tools (4th Report)

Selection of Temperature Control Methods Suitable for Lathes and Machining Centers with Different Thermal Characteristics

Abstract

Thermal deformation characteristics of machine tools are quite different with each other, and they greatly depends on their machining accuracies requested. Meeting on their characteristics and machining accuracies, many temperature control methods have been developed to improve them. This paper deals with selection of temperature control methods suitable for machine tools with various characteristics. Every temperature control method is evaluated in its temperature deviations and cost. From this study charts which show the controllable and suitable range of every method for machining centers and lathes with different thermal deformation characteristics.
