Study on tool influence function(TIF) of dual-rotation wheeled polishing
This paper presents a dual-rotation wheeled polishing tool which has the properties of high MRR and ideal shape for the tool influence function.It can be used in the fabrication process of large aperture aspheric optical component.The structure of the polishing tool is consists of a rigid cylindrical wheel and the polyurethane polishing pad adhered to wheel.The velocity distribution in the polishing contact area is analyzed according to geometry of the tool motion.Finite element method(FEM) is applied to acquire the contact pressure distribution.The TIF model with high central removal is built according to the Preston equation, and the form of TIF is Gaussian-like.The verification experiment for simulated TIF is carried out based on the experimental prototype designed by our group.The results indicate that the 2D simulated and measurement results of TIF show basically agreement, and the peak removal rate (PRR) is ~5 μm/min.
