Lamest maching question ever -- mill reach

[juno]

I blame my stupid question on being a girl. Just kidding. I blame it on a lack of machining experience.

I performed a draft cut of a part tonight with the .125 flat end mill. It looks good. When I swapped it out for my .032 ball end mill, I began thinking: won't the taper where the end mill meets the larger shaft that goes into the collet cut into my part? The part is deeper than the .032's reach.

Am I condemned to only machining parts within the end mill's reach or with a curve or a step or is the MDX software smart enough to know it's going to cut in and avoid that area?

Help!

you have to relieve the endmill back far enough to clear,but remember you can only cut so deep with a small endmill,and need to take smaller cuts as is can deflect alot easier no that is relieved
