✦ Synopsis

The performance of a diamond tool is based on the protrusion rate. The protrusion rate inspection is a costly, labor-intensive activity in industry. Normally, about 20 to 35% of the protrusion rate is provided for the final inspection of diamond tools. There are five known methods used for the protrusion measurement: mechanical dial gage, electrical dial gage, surface roughness measuring machine, focusing by microscope, and manual comparison. In this study, a machine vision system was used as an inspection tool to determine the protrusion rate of a diamond tool. The method developed is a noncontact method without manual judgment. Three sets of field samples were used to demonstrate the proposed method for determining protrusion rate.
