NO Problem here on our YCI's, wet air, no-oil in blast, cheap tooling, etc. etc.

Sounds like a way to get there. What about a larger diameter face mill? Could get a decent cross hatch that way.

When ever I open the HMM parameters dialog, ALL my HMM ops go dirty. What gives is this normal?

Boss has imposed an 80% of spindle MAX limit on me. I cannot program any faster than 6400 RPM. The insert is ad-defacto nauseum gonna stay as HIS choice for roughing inserts. Testing shows that the 5000 rpm @ 200 IPM runs good with .025 D.O.C. Considering I'll be giving notice soon I guess I'll just leave it and let him fuss about the cycle time.

I need to rough out a mold cavity in 6061, and I am going to be using an 1" end mill with 2 (.375) round inserts. I normally run this tool @ 5000 rpm, 200IPM @ .025" D.O.C.. However this mold is going to run a lot longer than I normally like them too. My best option for speeding this up is to increase my D.O.C. Any body have any recommendations on what they do in this situation.

OK, I think I figured it out. When I select the stl I do not have to have it rotated, in the stl file. Mcam will rotate to the wcs in use. Does this sound right?

1) ran 1st op in verify, saved stl 2) opened stl in mcam and rotated with new wcs, tried to save with errors 3) ran 2nd op in verify using modified stl and nothing shows up for stock, progress counter goes up, but no tool or stock can be seen. I am being a little slow today and can't figure out what I am missing.

OK, I set up new wcs and tried to save, didn't work. Said no surfaces existed (of course not it's an stl) The filename appeared, but was empty. So, what am I doing wrong?

When I save an stl from verify, and then proceed to use it for a stock model in another operation/set-up, do I need to actually rotate the stl model, or just use a new wcs?

I vaguely recall seeing this, and it was the way I had my options for my operation set-up. Double check everything, I seem to re-call something was INC and needed to be ABS. HTH

WHat a perfect example of how this forum helps people out in a pinch!
