Method and apparatus for removing a predetermined amount of material from a bottom portion of a dovetail slot in gas turbine engine disk

摘要

A system and method of removing a predetermined amount of material from a bottom portion of a dovetail slot (14) in a gas turbine engine disk (12), including the steps of configuring a designated flow path (38) through the dovetail slot (14) and providing a flow of abrasive media (26) through the flow path (38) a designated number of cycles so that a substantially uniform amount of material is removed from the dovetail slot bottom portion (20). The method also includes the step of sealing a pressure surface of the dovetail slot (14) to prevent the abrasive media (26) from flowing thereagainst. <IMAGE>
