I’m doing cutouts using .19" pine luan. I switched from an 1/8th to 1/16th inch end mill (feed: 30, plunge: 20, rpm 21000, depth per cut .28.
I’m having a couple of issues.
During the cutting the machine is staggering/stuttering (that’s the best way I can describe it).
Portions of the cut are burning
The machine went off the original toolpath and cut a shape out about 4 inches to the left of where it had originally been programmed to do so.
I’m still new and learning so any advice on what I might be messing up would be appreciated. I did manage to do several cutouts with that bit on those settings successfully before suddenly running into this issue.
In case other folks come across the thread what numbers worked better for you? I recently did some baltic birch cutting and based on GWizard kept it at .1" depth of cut, though I ran it a bit faster at 50ipm.
Dan, good thought. I adjusted the feed to 40 and plunge to 25. I also changed the depth per cut from .28 to .14. I also tightened the Y axis belts as they seemed a little loose to me. I’m not sure which adjustment did the trick but its humming along wonderfully now. I’ve attached a pic of the project.
