Here's a pic after a facing cut on the side of one of the plates. Tool is a high speed steel uncoated 1-1/4" 6 flute end mill. Had this tool in the box brand new for who knows how long and never used it, so we gave it a try. Vertical marks are where we were a little inconsistent with the feed rate. If I remember the plate is about .040 over 6" so we have room to experiment with the best feeds and speeds. We were climb milling at about 300 rpm, feeding at most 2" per minute. Well, sometimes 0 ipm, but the operator was learning. No worries though, we'll get it. One of the good things about machine work like this is that no matter what you're trying to do, it's been done so there's plenty of resources and knowledge around.
