Optimizing grinding and dressing with 'dressing speed ratio' parameter
The dress speed ratio is the relationship between the dress roll velocity (V r ) in sfm or m/sec and the grinding wheel velocity (V s) in sfm or m/sec. and can be calculated using the following equation: Speed ratio = V r ÷ V s. The dress speed ratio can be a positive or a negative value as shown in Figure 5.

Which Grinding Wheel Should I Choose? | Norton
For this reason, finer grit sized wheels are required to grind hard materials and soft materials are best ground with medium to coarse grit size wheels. For most efficient operation, the grade must be adjusted to suit the hardness of the material. As a general guide, the harder the material, the softer the grade of wheel required.

Ask The Grinding Doc: Decrease diameter, increase speed
The Doc Replies: If you want more consistent grinding, maintain a constant surface speed. The basic equation is: new rpm = original rpm × original diameter ÷ current diameter. So, if you were happily running your new 18" wheel at 1,800 rpm, once it gets down to 15", run it at 2,160 rpm (1,800 × 18 ÷ 15).
