Dressing tools with controlled abrasive grain population for grinding aerospace materials
Published 2018“…Thus, the dressing operation is utilized to obtain the required grinding wheel conditions, restoring the profile and preparing the wheel surface through the utilisation of diamond abrasive tools. The state-of-the-art in dressing technology presents several limitations in terms of abrasive arrangement (grain size, shape, protrusion and distribution), leading to non-optimal process results and limiting the tool life; this limits the tool performance, with consequent increasing of the costs related to both dressing and grinding. …”
