Abstract

Maximizing productivity in an optics shop requires that polish cycles be minimized. Polishing involves removal of the damaged surface layer of the lens. This damage is incurred in the rough and fine grind operations preceeding polish; minimizing surface damage coming from these operations is critical. Both chemical and mechanical processes play a role in polish. While the chemical process is not completely understood and varies widely with materials, the mechanical process is relatively well understood. Its effectiveness is directly proportional to the pressure and relative velocity between the polisher and the lens. By increasing pressure and speed, the polish cycle can be shortened. However, maximum values of these parameters are limited by lens configuration, material, and hydroplaning effects that may occur at higher relative velocities. Techniques for mitigating these limitations through the use of the right equipment, tooling and processes are discussed. Additional methods for achieving productivity gains through the use of integrated cells which combine all operations into a single area, controlled by a single operator, are also discussed.
