D14 On-machine surface form evaluation of a large-scale roll workpiece

Abstract

This paper presents the on-machine surface form evaluation of a large-scale roll workpiece on a drum roll lathe. In this research, the surface form of a large-scale roll workpiece, which is composed of the out-of-straightness, the out-of-roundness and the differences of the diameter along the axial direction of a large-scale roll workpiece, is measured by using two capacitive type displacement probes placed on the two sides of a large-scale roll workpiece
