Control effects of thermal deformation by machine tool using environmental characteristics of the factory

Abstract

Thermal displacement affects the machining accuracy of machine tools, and various countermeasures are being considered. For example, there are methods to suppress the temperature rise of the machine by cooling the heat source. The most common method for cooling heat sources is to circulate cooling water at a constant temperature, but this involves an increase in cost and energy consumption. This study devised a way to stabilize machining accuracy by utilizing the environmental characteristics of a factory and devising a machine tool bed structure that utilizes air with a relatively stable ambient temperature.
