An abrasive article comprising: a first body comprising a first bond material having abrasive particles contained within the first bond material, wherein the first body comprising the first bond material comprises a ratio of V/Vof at least about 1.3; a second body comprising a second bond material having abrasive particles contained within the second bond material, wherein the second body comprising the second bond material comprises a ratio of V/Vof less than about 1.3, and wherein Vis a volume percent of abrasive particles within a total volume of the first or second body respectively and Vis a volume percent of the first or second bond material within the total volume of the first or second body respectively.

Bonded abrasive article and method of grinding

An abrasive tool includes a bonded abrasive body having abrasive grains contained within a bonding material, wherein the bonded abrasive body comprises a complex shape having a form depth (FD) of at least about 0.3. The form depth is described by the equation [(Rl&#x2212;Rs)/Rl], wherein Rs is a smallest radius (Rs) at a point along the longitudinal axis of the bonded abrasive body and Rl is a largest radius (Rl) at a point along the longitudinal axis of the bonded abrasive body. The abrasive tool can be used to finish complex shapes in workpieces.
