slight Vee shape. This curls the chip inward as it rolls up,
making the chips narrower than the groove. I do cutoff
work fairly fast, often on the lowest direct-drive speed on the 10-12"
Especially on aluminum, I would only advance the crossslide about
one turn before backing the cutter out and letting things cool. I
would keep a toothbrush saturated with cutting oil in the groove
all the time I was cutting.
