I had a part with 4 of the same cuts in it so I programmed the first 1 then Mirrored it to the second third and 4th location then ran play path and everything cut fine. I then ran Module works and it showed the cut cutting outside of the windowed cut so I turned in a case about module work showing gouges or collisions where play path didn't. I started a support case#13023191 where Module Works gouges and play path doesn't

I wasn't sure which to trust. So now the issue goes to why is play path not showing the proper tool path?
Solved! Go to Solution.
Yeah, it's a rule of thumb in Creo, avoid mirrors at all costs. Only things that work with a mirror are sketches and curves, and i'd avoid doing that anyway. I always just use paste special.
Why on earth would Creo 3.0 not show the wrong paths in play path i have no idea, seems like a bug.
Damn. What version of Creo did that?
James,
It is Creo3.0 M090. I suspect it is the way I programmed it. with just 1 window or volume and programmed cut then mirrored everything. My fix was to go back in and just mirror the window or volume and not the cut then it worked fine. It still is a software bug I believe. You should be able to do it the original way I did it without error.

I never use mirror, I don't find this very reliable. In your case, I would make a single window with a sketch of the 4 regions you want to mill.
I found out it's not reliable!! From now on I will just use the mirror for the window or volume geometry not the cut. I still think it should be able to do mirrors as I did and it is a bug in the software or a bug in the play path portion that doesn't show the gouge.
Steve, did you try to use Gouge Check for CL data file generated from mirrored sequences. It would be interresting if CREO is able to detect above mentioned undercut.
I don't usually run gouge check on plates like this but to satisfy your curiosity as well as mine I went back to that plate and set the plate up with the mirrored cuts just to see if gouge check would find the gouges.
It did find the cut into the part!
the reason I don't run gouge check on plates like this is there are a lot of drilled holes and gouge check ignores them so it really isn't that useful.
and most of the cuts in the plate aren't that critical.
Sorry I clicked into the bad message winow.
For mirrored NC sequences, it seems that toolpath displayed in Toolpath player and toolpath generated into the CL file are diffrerent. We had similar problem few moths ago.

Yes they are different I believe it's a software issue. If you are allowed to mirror the sequence it should follow the original sequence.
