Has anyone experienced surface finish peculiarities when using PCD and making an interrupted cut? The finish was fine with carbide but is, for lack of a better word, “sandy” with the PCD insert. Switch was made for chip control reasons. The finish from PCD is beautiful everywhere except on the portion of the cut that is interrupted. Carbide didn’t show such a difference. Material is 6061-T6511 being cut with a DPMT 21.51. 5/8 carbide bar hanging out 4.125” from a split bushing (Sandvik Easy Fix). 780sfm (unbalanced part) and 0.004 ipr on a Multus B300W. Tool ran 100 pcs Op10 and 80 pcs Op20 without issue. New insert is great except for the finish at this one point.
