Trochoidal milling


Trochoidal milling

Hi users,

I am milling 718 inconnel for the first time. I am cutting an open ended slot not thru the part. I am using a mill window with rough only,constant load,and a CORNER_ROUND_RADIUS to get a spiraling radiused cut. There is a exit and approach move that is about 1/2 the diameter of the cut. Is there a way to shorten this up to reduce cycle time? I am also aware that rubbing can cause problems with cutter and work hardening. The bottom of the cutter will be in contact with the slot bottom. Will this be a issue and can I ramp up as I move the cut in.
