Machining Waspaloy

First of all What is Waspaloy?
Waspaloy is a precipitation hardening, nickel-based alloy which has been used in elevated temperature applications. The alloy has been used for gas turbine engine parts which require considerable strength and corrosion resistance at temperatures up to 1600°F (871°C). Waspaloy is usually vacuum-induction plus consumable electrode remelted.

Waspaloy Corrosion Resistance?
Waspaloy has excellent resistance to corrosion by combustion products, encountered in gas turbines and aircraft jet engines, at temperatures up to 1600°F. Intergranular oxidation occurs at temperatures above 1600°F.

Waspaloy Machinability
Waspaloy is difficult to machine in any condition of heat treatment. The air-cooled, solution treated condition is best for most operations (this is Rockwell C 30 partially aged). Rigid, well-powered machines are required for best results. Cemented cardide tools are preferred for most operations and care must be exercised to obtain positive cuts at all times, otherwise "glazing over" and work hardening of the surface will occur.
The following tool geometry, feeds, and speeds have been found satisfactory for lathe turining:
0° back rake
6-8° side rake
5-8° clearance (end and side)
15-20° lead angles may be used to reduce feed pressure on roughing cuts.
Speeds of 35/50 sfm will feeds of 0.005/0.15" per revolution are recommended. Slower speeeds and greater feeds should be used for roughing cuts and faster speeds and lighter feeds for finishing cuts. Better tool life will be obtained by machining in the solution treated condition; however, a smoother finish can be obtained by machining in the fully aged condition.
