ARTICLE ANNOTATION

quote
This article presents a numerical study of the thermomechanical state of the rotary unit of a five-axis CNC machine. Using the finite element method, a coupled analysis of thermal fields and the resulting housing deformations was performed. Zones of maximum heating and their influence on the magnitude of spatial displacements were identified. The obtained results allow us to estimate the contribution of thermal factors to the positional error of the rotary axis.
