Was making a part and had to mill to size. It was a 1.375 long .675 square part that I needed to mill down to .510 on one side. It was only rough cut on the ends so I didn't square it up. Finished my cut and the part was out of square .003". Since the part was ruined I decided to square all sides with no difference.
I then took some measurements on the vise. With the DTI attached to the spindle I ran across the stationary jaw, no movement. Then I put a parallel in the vise and ran the indicator along the top, still no movement. Then I went along the Y axis on each way of the vise. Still nothing. When I jumped over to the other way just next to the solid jaw I saw .0004" movement.
I then cut a small square piece and proceeded to square it up, this time with my Superfly instead of an endmill. I was curious if trailing edge on the Superfly would cut. As I went from left to right there was a lot of contact with the trailing edge, more than normal I would say. From right to left I didn't hear any contact. I just trammed my head a couple weeks ago but I guess it must of come out. I'm surprised though as my reading on the vise were all fine.
Any other thoughts on this?
