Abstract
A workpiece includes a surface adjoining an aperture. The aperture is filled with a plug to provide a step adjoining the surface. A stream of pliant shot in a carrier fluid is discharged at a shallow angle of incidence against the plug and directed toward the step for selective abrasion thereof.
Claims27
A method of treating a surface adjoining an aperture at a corner in a workpiece comprising:
- filling said aperture with a plug;
- and
- discharging a stream of pliant shot in a carrier fluid at a shallow angle of incidence against said plug and directed toward said corner for abrasion thereof.
A method of radiusing a corner between an aperture and adjoining surface of a rotor disk comprising:
- filling said aperture with a plug to expose said corner;
- and
- discharging a stream of pliant shot in a carrier fluid at a shallow angle of incidence against said plug and directed toward said corner for radiusing thereof.
A method of deburring a corner between an aperture and adjoining surface of a rotor disk comprising:
- filling said aperture with a plug to selectively expose burrs at said corner;
- and
- discharging a stream of pliant shot in a carrier fluid at a shallow angle of incidence against said plug and directed toward said corner for deburring thereof.
A method of scrubbing a corner at an aperture in a workpiece comprising:
- filling said aperture with a plug to expose target material at said corner;
- and
- discharging a stream of pliant shot in a carrier fluid at a shallow angle of incidence against said plug and directed toward said target material for abrasive scrubbing thereof.
