Capstans or lead screws? Comparing the performance of diamond turning machines under operating conditions

摘要

The cutting performance of diamond turning machines which employ lead screw driven slides is compared to that of similar machines which use capstan drives. Diamond turned parts are compared using Talystep, Form Talysurf, and Zygo Mark 2 interferometer data. Machine contouring performance is compared using a sinusoidal path technique.
