ABSTRACT:
Grinding control methods and apparatus pertaining generally to maintaining the shape and sharpness of a grinding wheel, despite the tendency of the wheel face to deteriorate from the desired shape and sharpness, as grinding of a given workpiece or a succession of workpieces proceeds. Generally, as a common denominator of the novel features disclosed, a "conditioning element" is brought into rubbing contact with the face of the grinding element under specially controlled and unique conditions to (i) restore the desired shape (conventionally called truing), or (ii) to establish the desired degree of sharpness (conventionally called "dressing"), or to accomplish both (i) and (ii) simultaneously. The methods and apparatus disclosed include creating the aforesaid controlled rubbing contact either while the grinding wheel is free of grinding contact with a workpiece or simultaneously while grinding is occurring, and then either continuously or intermittently. The methods and apparatus in many of their various embodiments involve use of a "truing element" or a "conditioning element" which may be a generally homogeneous metal, and in many cases the same metal as that of the workpieces being ground. This advantageously results in lower costs as well as greater productivity and workpiece quality (both size tolerance and surface finish).
