Completed a bowl bottom finishing chuck for my lathe.
This was a perfect application for my CNC as I needed to make two of them and they needed to have a center recess and an array of slots that were accurately placed.
Still figuring out the whole “chip load” speed and feed thing out but getting closer.
I found that I have fallen into the newbie trap of feeding to SLOW for my spindle speed. I typically run at about 32ipm cause the cutting sounds good. By calculation for my spindle speed, I could run almost 5x that. I can’t imagine my CNC running >100 IPM in plywood. So I guess I need to slow down the spindle?
The problem I have is that my spindle motor controller will not go slow enough …uggh!
For that reason, I cannot slow down the spindle speed to match the feed ability of my CNC.
This known problem came back to bite me.
