Abstract
Grinding control methods and apparatus pertaining generally to maintaining the shape and sharpness of a grinding wheel 20, despite the tendency of the wheel face to deteriorate from the desired shape and sharpness, as grinding of a given workpiece 24 or a succession of workpieces proceeds. Generally, as a common denominator of the novel features disclosed, a "conditioning element" 50 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 softer, equal to or harder, or vastly harder than the grit of the wheel, and which may be diamond, a generally homogeneous metal, and in many cases the same metal as that of the workpieces being ground. In their different facets, the disclosed inventive features involve truing of wheel faces by controlling relative surface speeds and feeds of the wheel and the conditioning element. <IMAGE>
