| Abstract;Much of electric energy which flows into machine tools finally changes to heat. Electric energy which is concerned with actual machining is about 2/3 on the basis of energy distribution, and most of it is used as chip heating heat. Heat generation places inside machine tool are mainly main shaft sections, and the temperature change behavior caused by heat generation sections is related with heat generation quantity and the behavior of thermal deformation. This paper explains thermal deformation of machine tools and fluidic characteristics of chips as a source of thermal deformation. As estimation of thermal deformation, this paper deals with heat generation and thermal deformation of main shaft sectins, thermal deformation of actual machine tools, and deformation by ambient temperature changes. Regarding thermal and fluidic characteristics of chips, this paper deals with thermal conductivity of chips and heat transfer to cooling fluids. |
