The Tool Path Planning for Ring Torus Optical Surface Diamond Turning with Parallel 2DOF Fast Tool Servo

摘要

FTS (Fast Tool Servo) has always been an important method for manufacturing non-axisymmetric optical surface. In this paper, a novel tool path planning method is presented which plans tool path in two coordinate directions of a parallel structure 2 DOFs FTS simultaneously. Comparing with single DOF FTS, this method has significantly improved the ability of producing non-axisymmetric optical surface, such as ring torus surface.
