Update.
I spent a few hours yesterday trying to implement some of the suggestions listed above. I dialed in the orientation and center height of the insert as best I could. No change in finish. I also tried upping the speed/feed/DOC but that didn't change anything.
Today I threw a different boring bar in the machine, and it worked like a charm. 45/45 parts were on size first time...no scrap. The finish was like glass for the first dozen or so parts and then gradually took on a matte finish. No issues with BUE, smearing, chip packing, or other major calamities and thus the parts were still good. Progress! I kept the speed/feed/DOC changes from yesterday and they will at least cut down some on cycle time. Looks like I owe Frank a beer, as it does indeed look like the insert pocket was loose.
I'm still looking forward to hopefully hearing from Kyocera tomorrow on the cermets. I'm definitely curious.
Anyway, up and running again so that is a good thing.
Thanks for all the suggestions!
