Abstract:

Tests to determine the feasibility of high speed milling edge trimming are in progress. Preliminary test results indicate that high speed milling offers a better than average potential for success in edge trimming 6Al-4V titanium sheet and 15-7 Mo sheet in the 500 to 2500 feetminute cutting speed range. Drilling tests have been made using the Tornetic drilling unit and a constant speed drill press on D6AC steel in the 54-58 Rc hardness range. Tapping test results on B-120VCA titanium at 400 BHN are presented comparing the Tornetic tapping data with conventional tapping. Machining test data is also presented on B-120VCA titanium, TZM Molybdenum, Mo 0.5 Ti and D-31 Columbium alloy.
