摘要:
A method for forming a slot in a rotor disk includes a finishing step using a tool rotating at angle off normal in direction opposite a direction that the tool is driven through the slot. A finish profile is obtained in part by removing material from a bottom surface with a tool rotating about an axis off normal.

A coolant nozzle is used on a machine tool having a rotating bit of convoluted longitudinal profile for cutting a number of slots in a disk. The nozzle includes at least one coolant inlet and at least one coolant outlet. The coolant outlet has a convoluted section and is positioned to direct a coolant stream tangentially at the bit in a direction of rotation of the bit. Internal surface portions of the nozzle define one or more passageways between the inlet and the outlet(s).
