Grinding with patterned grinding wheels [PDF]

open access: yesCIRP Journal of Manufacturing Science and Technology, 2015
Grinding is one of the most important manufacturing processes, especially when high surface qualities have to be realized or if hard or brittle materials have to be machined. Often the grinding performance is limited by workpiece failure due to a high thermal load in the contact zone.
