A Study on Measuring Surface Topography of Grinding Wheel on the Machine (2nd Report)

Cutting Edges under Various Dressing Conditions

Abstract

The aim of this study is to estimate the cutting edges on a grinding wheel surface under various dressing conditions. Therefore, the surface topography of the grinding wheel in the entire periphery is measured in three dimensions using a laser stylus unit on the machine table. At a present report, we investigated positions, numbers and profiles of the cutting edges on the grinding wheel from measurement results under various dressing conditions. As results, it is clear that there are few cutting edges on the outer periphery (depth 3 μn from the maximum height of the cutting edge) of the grinding wheel. In particular, the lead of wheel dressing has influence on the surface of this area. As the dressing leads decrease, the number and the vertical angles of the cutting edges increase.
