I went to buy a piece of 3/8 6061T6 today. My usual supplier did not have any but did have some very nice looking Alcoa Cast Aluminum, exactly .375 thick. The sales person assured me it would cut just like 6061T6.
Bought it, should not have! Using the same speed and rate as I do for 6061T6 it gums up the bit, and makes a terrible mess! Broke two carbide bits before giving up on the project.
Can someone tell me the speed and feed that I should be using vs. 6061T6?
Only trying to cut .015 depth per pass, 10,000 RPM, and 30 IPS. Works great in 6061T6, disaster in Cast Aluminum.
