INTRODUCTION

MICROGRINDING of optical glass with precision machining systems (CNC) has been gaining momentum in the past years as a new technology for optical manufacturing. Development of the technique is under study in both industries and academic institutes, including the Center for Optics Manufacturing (COM) at the University of Rochester. At COM, micrometer-scale diamond abrasives (
