Paper Abstract

We investigate three-dimensionally configured (shaped) polishing pad materials in CNC polishing and introduce a cost of ownership model representative of a typical manufacturing process. Several different types of polyurethane polishing pad materials possessing different material properties and configurations were studied. Their utility as polishing tools was evaluated in terms of the finished part specifications and part-to-part consistency. Data shows the use of IC Optic Puck material with a grooved configuration provides optimum performance and consistency for CNC polishing processes. Furthermore, we extend the investigation and provide a cost-of-ownership model that can be used to estimate the benefit of such a tool platform for an optic manufacturing process.
