This is exactly how you machine a part efficiency Fast af

If you turn the coolant on you can go even faster.

I've started running two endmills the last few weeks for fun I used run a finishing endmill if I could get away with it, especially on aluminum but now I'll use a rougher and switch my cutting from climb to both ways on tricordiol cuts. Working well. Climb with finisher 🤌

Very fast... Can always do better... Milling the air:

What is the point of the move at :08 seconds and again at :19 seconds? Looks like a 45 cut on the corner

Ya we have been doing this for 100 years now da

We often see (new) machinists optimize for minimum tool changes or tool life, but without factoring time value. Burning through $200 end mills might be expensive, but you may well make that back in increased production.

Finish passes could be way faster. X3 with a high speed mill
