Hello
I am searching for the proper type of mill bit to most efficiently perform a profile operation on 6061 aluminum.
Said job is as follows; Stock measures;1.5" x 3". It's a profile operation with a cutting depth of -1.5". I need to make 20(ea) of them
My initial thoughts are to run an .5" end mill around the profile to -1.5" depth then perform the same operation using a .1875 end mill to remove the remaining material. The way I see it, load on the end mill will primarily be in the -z direction. I'm thinking 2 flute HSS. Down cut? Thanks to all who respond.
