Hello,
I recently started machining a section out of a part for tensile tests.
I cut two dogbone shaped pieces and they need to be as accurate as possible obviously. I cut 2 pieces out of the same part, 1 is a vertical section and 1 is a diagonal section.
When I cut the vertical section it comes out with a great finish, it measures at exactly 8mm which is what we need, but the diagonal piece is different. The edge finish is wavy and measures 7.9mm at one edge and 7.65mm at the other side.
Is there something you guys can think of that would be causing I’m the diagonal piece to cut so much worse than the vertical?
