Abstract
This invention is a new high wheel speed grinding process that uses only one very hard grade resin bonded grinding wheel of the desired abrasive grit size for the surface finish required, where simultaneously with the grinding of a workpiece the wheel face is conditioned and trued by a truing element heated to a temperature between 250.degree. F. and 1200.degree. F. at the truing rates required to provide grinding at quantitatively predictable desired and constant unit volume energy and metal removal rate values. Because of the hard grade wheel specification, the wheel face would quickly revert under any job situation to a dull wheel face without this conditioning and truing. Under any forseeable job situation, conjoint control of the temperature of the truing element and the truing rate controls wheel wear rate. With wheel wear rate controlled, continuous compensation for wheel wear is made and results in a grinding process where metal removal rate is equal to the relative volumetric feed rate of the workpiece and the wheel. The metal removal is shared uniformly across the entire wheel cutting face regardless of plunge or transverse grind configuration because of the orientation of the truing element relative to the direction of the volumetric feed.
