Abstract
This paper deals with a three-dimensional deformation analysis of workpieces mounted in fixtures, where the workpieces are finite solid cylinders. The analysis is carried out using a three-dimensional theory of elasticity, where clamping forces caused by chucks are regarded as an axi-asymmetrical load. In numerical calculations, the effects of a number of chuck jaws, the diameter of workpieces and the grasping area on the roundness of the workpieces are shown. For verification, a three-dimensional photoelastic experiment is performed. In addition, the deformation of workpieces is measured by an electric comparator and by holography. The analytical results are satisfactorily consistent with the experimental results.
