I’m hoping to pocket a bunch of 3.5mm holes in some 10mm aluminium plate using a 1/8" 2 flute carbide end mill using carbide create / carbide motion. I was thinking because 1/8" is 3.175mm and plus 10% makes 3.5mm so should be fine with pocketing command in carbide create.
I just ran a test hole and rather than cutting small amounts at a time, the router plunged straight through in one hit and cut the hole in about 5 seconds! I was expecting it to trim small amounts at a time. Obviously this puts too much strain on the end mill, anyone know why it plunged through rather than going slow?
Settings I used:
Depth per pass: 0.254mm
I made a larger 7mm hole using the same settings and it drilled it out in small increments as I was expecting.
