5.3 grinding forces, power, and specific energy. forces are developed between the wheel and the workpiece owing to the grinding action. for plunge grinding operations, as illustrated in figure 5-2 for straight surface and external cylindrical grinding, the total force vector exerted by the workpiece against the wheel can be separated into a tangential component f t and a normal component f n.
an excerpt from abrasives methods by francis farago, 1976 out of print. grinding wheel speeds should be maintalned with-in a range of 5000 to 6500 feet per minute 1525 to 1980 meters per mm , unless special conditions prevall or equipment and wheels designed for substantially higher wheel speeds are used.
