Hey fellas,

working on milling some 1/2" wide slots in h13 approximately 1/2" deep. cutter is a TiALN coated 3/16 carbide. Right now speeds are 250sfm(ish) feed rates are around 7ipm. chip load is about .0005

I say "about" because I didnt program it just glanced at the mastercam settings.

So the tool has a bit of squealing to it, but it seems to be cutting fine. Just want to make it through these 4 slots without killing the cutter. current DOC is .188. should i just go ahead and cut it full depth? Using the mastercam peel path with a 6% stepover.

Advice is appreciated. first time cutting something this hard.
