Efficient estimation by FEA of machine tool distortion due to environmental temperature perturbations

► This paper significantly contribute towards the reduction of machine downtime required for environmental thermal testing. ► Provides a novel, offline and efficient solution based on FEA to ensure machine tool's availability for production. ► the existence of environmental temperature fluctuations within shop floors and experimentally shows the effect on machine tool's precision. ► that industries avoid and neglect environmental thermal testing due to the associated machine downtime. ► The paper shows experimental testing, results and successful validations using FEA simulation.
