Thanks! The cut took about 1 hour and 45 minutes. I was doing a 1.5mm DOC at 26mm/s w/ 15% step-over. The deepest part of the cut was about 3.5mm. I have my spindle on a rheostat, and it was turned almost to the bottom; not sure what RPM that puts me at, but I slow it down until the chips look like, well, wood chips… These are some of the first cuts I’ve done on wood, all of my previous machining experience is in aeronautics alloys (inconel, hastelloy, etc.). I’m still very much a novice at wood feeds/speeds I’m afraid, and not knowing how fast my spindle is turning is kind of driving me nuts.
