For starters, I would use several endmills to get there...each being longer than the next...ultimately the longest endmill would only be nibbling at the depths but it would be limited in cuts to only what it can reach.. I would use a drill to remove as much material as I could, using something like a 65-70% stepover... Finish by using ramp cuts to keep the tool engaged..speeds & feeds will be varied by the different reach tools...lonest crawling along

Click the "Perpendicular Entry" box on the cut parameters branch

Thanks Pete.... We did figure this one out

Bill, the code you seek is in most of the newer Gen Haas posts...

If you can export them as a dxf file perhaps, that'll get it done

Filtering your toolpath.... Though it it's not in a plane that can create arcs.....you can still filter but make sure your tolerances are tight... I typically run a .0006" total...this is on a .047" ballmill with a .0025" stepover

The files I work with tend to grow to hundreds of megs.....I end up restarting Mastercam at least a couple times a day... It's been that way for so long it's something I no longer think about, just end up doing it...

Mastercam files cannot go back to previous versions of Mastercam...

It's usually better to share a Mastercam file setup up the way you need it, as 5 axis cuts are particular

How about sharing a Mastercam file instead...

Xform >> Scale Looks like a .4 scaling value

You can also set it to default for a particular machine in the machine def

From what I have heard, CNC Software will continue to operate as its own entity...I guess we'll see how that plays out of the short & longer terms

You can use Peel MIll with a single line, you just need to tell it the width... In that tools case, you would use the smallest diameter on the tool as the defining tool size..
