Cutting Tool Applications, Chapter 16: Grinding Wheels and ...
Grinding pressure is the rate of in-feed used during a grinding operation; it affects the grade of wheel. A general rule to follow is that as grinding pressures increase harder wheels must be used. George Schneider, Jr., is the author of Cutting Tool Applications, a handbook to machine tool materials, principles, and designs.

Grinding Wheel - an overview | ScienceDirect Topics
The grinding wheel is still a surface of revolution whose axial profile curve coincides with (or, is very similar to) the cutting edge, whose geometry depends on the tool type (straight blade, curved blade, with Toprem, etc.). For a straight blade tool, the corresponding grinding wheel geometry is specified by the four parameters in Fig. 4: r e, edge radius; α, blade angle; R p, point radius ...
