Detection of Ring Tool Misalignment Using an Imaging Method

Abstract

The Opticam computer-controlled optical surface generator1 uses a cylindrical grinding geometry. The radius of curvature of the generated surface is determined by the radius of the ring shape diamond-impregnated cutting head and its tilt angle. The edge of the ring cutter will coincide with the part vertex when the machine is aligned. When the cutter axis is not properly aligned with the part axis, the generated surface will deviate from its desired shape.
