This is a piece I'm working on, it's in the vise for the picture.
I've noticed this in the past and just wrote it off. However, this time I'm actually trying to make a nice looking piece.
It seems I get some kind of chatter in my end mills without my machine actually chattering.
I'm the picture, you can see it in the last pass on the northeaat side of the picture.
Little gouges. This was with a 1/4" 4 flute roughing end mill in mild steel, but I've also seen it in aluminum with a 1/2" 2 flute end mill. Both are relatively new, fairly sharp, and not chinese. I've even seen it in my carbide fly cutter.
I don't feel I'm feeding too fast, or running too high of speed, I try to keep the chips somewhat clear, but the consistent pattern doesn't make me think chips.
The machine is a busy bee mini mill, don't ask me the exact running and feeds speeds cause I have no way of knowing what they are.
The only thing I can think of is slop in the x axis, but I'm power feeding, and it's all fairly tight...
Could a Ben's in the lead screw cause that? How could I detect that? I don't think the table surface is smooth enough to run a dial test indicator accurately.
Thoughts?
