I see.. I think I was assuming that was the answer but I really wasn't sure. Some of those tutorial videos assume a certain level of experience on the end users part. SO the Pass Depth would be applied to a ROUGHING pass if I chose this bit and assigned it to that purpose.
Adrian, I noticed in one of the threads about the tapered ballnose type cutter you mentioned you rarely use the roughing pass. That is pretty much what I have decided on since I rarely carve anything which is going to exceed .375 in max depth and the majority of my projects are set to .25 max depth. With the tapered ballnose bits this seemed to be the way at least 50% of the forum users said they also run their jobs.
I have started to design my projects with a slower rate of feed and then I gradually step it up after the first passes have been made. I know it might be a little riskier strategy but it's been working for me with the type of jobs I run.
