Engineered grinding tools reimplemented by precise sharpening: A case study on an ultrahard ceramic matrix composite (CMC)

Abstract

Engineered grinding tools have demonstrated potential for superior grinding performance but the lack of efficient and consistent dressing methods could lead to their discarding when worn. Here, a new dressing technique based on laser sharpening of the individual abrasives of an engineered grinding tool is attempted after inducing wear by grinding a SiC/SiC CMC. Not only ductile grinding was achieved consistently on the CMC surface with the engineered tool, but also the wear rate of abrasives is improved. The sharpening trials successfully enabled the individual cutting edges for subsequent endurance tests, whose results were comparable to the as-received tool.
