Study of thermal behaviour in a machine tool using ansys

Abstract

Smart manufacturing plays a vital role in modern industry. This involves a collection and analysis of data from the machine tool. Also, it requires to study the behaviour of the machine tool. Since the thermal behaviour is critical, machine tool thermal distortion accounts to 60-70% of machining errors, due to which precision and accuracy will affect. The major factor is the thermo-mechanical deformation. Hence, there is a necessity to study the thermal behaviour of the machine tool to reduce thermal errors which results in better machining accuracy. The major thermal sources of the machine tool are internal and external heat sources from spindle and axis movements. In order to study & analyse the influence of thermal sources on the machine tool, this paper focuses on the thermal error modelling approach using FEM (Finite Element Model) analysis. SOLIDWORKS 2016 & ANSYS Workbench 18.1 is used for modelling and to analyse the thermal behaviour mapping.
