Static Stiffness Modeling of a Novel PKM-Machine Tool Structure

Abstract

This article presents a new configuration of a 3-dof machine tool with parallel kinematics. Elastic deformations of the machine tool have been modeled with finite elements, stiffness coefficients at characteristic points of the working area for different cutting forces have been calculated.
