Abstract
A method and apparatus for profiling a grinding wheel (12) used to grind a workpiece (6) includes selectively feeding the grinding wheel radially against a dressing roller (19) to dress the wheel. Between successive dressing operations, the dressing roller (19) is conditioned with a conditioning wheel (50) movable radially thereto. Either the dressing roller or the conditioning wheel is movable axially relative to the other. The dressing roller (19) makes linear contact with the grinding wheel (12), and makes pointwise contact with the conditioning wheel (50). The relative radial and axial movements between the conditioning wheel (50) and the dressing roller (19) are synchronized by program control.
