Selection of Materials and Processes

Abstract

The tutorial will be on the company owner's view in the selection of materials and processes for the manufacture of optical components, coatings, and sub-assemb1ies. It will start with the receiving of a quotation from the customer. Depending on the quantity requirements, either prototype quantities or large volume production quantities, it will have to be determined how to buy raw materials and a decision will have to be made on temporary or hard tooling. We will show a comparison of different manufacturers suppling the same type of raw materials and their impact on quality, price, and delivery. We will discuss interfacing between engineering or designers and manufacturers. A cost comparison will be made between single elements and large volume production. We will also discuss the effect of tolerances on pricing. One would also have to look if test equipment is available or will have to be modified or possibly purchased. Specifications will be discussed to establish coating parameters. We will also discuss the impact that quality, environmental requirements, and change orders have on delivery.
