Abstract
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−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.
Claims20
An abrasive tool comprising:
- a bonded abrasive body having abrasive grains dispersed throughout a three-dimensional volume of a bonding material, wherein the bonded abrasive body comprises a complex shape having a form depth (FD) of at least about 0.3, wherein the complex shape comprises a first radial flange extending from the bonded abrasive body at a first axial position and wherein the bonded abrasive body comprises an overhang ratio (OR) of at least about 1.3.
A method of operating an abrasive tool comprising:
- finishing a re-entrant shape opening in a workpiece using a mounted point abrasive tool comprising a bonded abrasive body comprising abrasive grains dispersed throughout a three-dimensional volume of a bonding material, wherein the bonded abrasive body comprises a complex shape having a form depth (FD) of at least about 0.3, wherein the complex shape comprises a first radial flange extending from the bonded abrasive body at a first axial position and wherein the bonded abrasive body comprises an overhang ratio (OR) of at least about 1.3;
- and
- plunge dressing the mounted point abrasive tool along a form length of the bonded abrasive body.
