Establishment of Production Machinability Data.

Abstract

Task I - A number of the newest tool materials such as coated carbides, composites (ceramics,) micrograin carbides, and Borazon tools which appeared suitable for machining aerospace alloys were tested. Several of these new tools permitted appreciably higher production rates in the machining of 4340 steel, Ti-6Al-4V alloy and Rene' 41. Task II - Machinability data were developed on the following alloys: (1) HY 180 steel, (2) Gatorized AF2-IDA, (3) P/M Ti-6Al-4V alloy; and (4) Astroloy (as HIP'ed). The table of recommendations prepared from these data provides machining information that is directly applicable to shop usage. Task III - End mill finishing and roughing data were developed on the following alloys: annealed 4340 steel, 217 BHN; annealed Ti-6Al-4V alloy, 321 BHN; and 7075-T651 aluminum, 179 BHN.
