[mfg-smartcam] Cast Iron Stability

[Jon Baker]

Hey all you Cast Iron Guru's,     I am machining a feed table with dove tails for a small milling machine manf, and I have a quick question.  I am cutting only on one side of this gray iron beast, taking about 1/4" off the top, plus another 3/8" step down to the bottom of the dove tails, plus cutting the dovetails.  All in one setup.  I have the casting clamped down to the table top of the mill.  The part is 22 inches long, and the dove tail is about 3" wide, 60 deg standard.          OK, now to the question, I know if I was cutting steel bar, it would warp like a mother....., but I have never cut this long a piece of cast.  Will it bow?  I know cast is supposed to be very stable, but..... I worry.   Thanks for your input Jon
