Abstract
A tool for producing a pattern of highly accurate and optical quality surfaces and the method of making same from a series of bi-metallic pins. A high strength metal pin is coupled to a slug of metal of lesser strength capable of being accurately scribed. The supporting pin blank preferably is magnetic stainless steel and the slug is of copper. A group of such bi-metallic pins then is placed in an appropriate fixture after which an optical configuration, such as the three faces of a cube-corner element, are scribed into the copper ends. A completed tool may then be electroformed to produce an electroformed tool from an array of like or different pins, arranged in various patterns.
Claims19
A bi-metallic pin to make tools for making optical quality parts, comprising an elongated pin having a first metallic portion having first and second ends, said first metallic portion being fabricated from a high strength metal;
- a second metallic portion, of lower strength than said first metallic portion and capable of being easily machined, being fixedly secured to said second end, and an optical pattern scribed in the end of said second metallic portion.
An electroforming tool for producing optical quality parts comprising a plurality of bi-metallic pins each comprising a first metallic portion fabricated from a metal of higher strength and a second metallic portion fabricated from a metal of lower strength than said first metallic portion, and capable of being easily machined being fixedly secured to one end of said first metallic portion each said second metallic portion having a pattern for producing an optical result formed therein.
