Abstract

The Primary Rockwell Hardness Standard System was set up in the Center for Measurement Standards since July 1996 till June 1997. During the period, a compact laser interferometer, HP10737R 3-axis interferometer system was used to measure the effect of pitch and yaw of the Rockwell Hardness standard machine. Considering to increase the performance of hardness measurement, the geometry of the diamond tip has to be determined. In this paper, we will present the results of indenter geometry by μ-CMM (Coordinate Measuring Machine) in CMS.
