I made the worlds simplest drawing of a representation of the feature I'm making. I left out a lot from the actual part and this only took me a minute so if it's still confusing that's why. I think it's better than trying to describe it though.

Thanks for all the help so far guys

drill a 375 hole to z-3.990 w a twist drill using a spot drill first.

position the first x position to -.05 from where center of.375 hole is to have room to turn on cutter comp for .500 hole...y position center of the .375 hole.we will use. 375 hole as a clearance hole to feed down in to do the .500 partial hole

T02 IS THE .375 END MILL .5625 LOL REDUCED SHANK

Make sure to have the N1000 thru m99 after the M30 and no other n1000 blocks besides that one in your program


let me know how it works.
