Finite element thermal simulation of a CNC milling machine

Abstract

This article concerns a thermal simulation of a 5-axis CNC milling machine by finite element method. At the early stage of a machine designing process, the analysis of thermal conditions is really important, because milling machines are exposed to heat effects. The result of it is a nonstationary temperature field, which can influence accuracy of positioning and it can generate thermal stress in the structure of machines. Besides harmful heat effects can decrease geometry accuracy of manufactured product, but making thermal analysis quality and lifecycle of products can be higher and planning time can be reduced.
