DETECTION OF ORIENTATION-DEPENDENT, SINGLE-CRYSTAL DIAMOND TOOL EDGE WEAR USING CUTTING FORCE SENSORS, WHILE SPIN-TURNING SILICON

摘要

The purpose of this project is to experimentally determine the benefits of spin-turning infrared materials known to cause relatively rapid wear of single-crystal, synthetic diamond cutting tools. The testing explores the specific issues of nonuniform workpiece properties (single crystal silicon), non-uniform cutting tool properties, and machining parameters. This work includes a description of a precision spindle-based tool holder that provides high stiffness and accurate rotation for turning optical-grade surfaces.
