Abstract

Thermal changes during diamond turning always present to some degree. For small parts with relatively short cut times, the effects can be minimal with modest thermal management. As parts become large and turning times increase, thermal effects can manifest themselves in a variety of ways. In this paper, we describe three different unique applications where temperature cycling and drift modified the original plan for part fabrication: a roll-to-roll embossed microprism array, a large diameter acrylic lens, and diamond turning a large mandrel.
