Hi ,
I've a difficulties to achieve the flatness .
How to do face cutting on aluminium plate without warp ? Any tips to avoid warping while the workpiece is being clamp by precision vice.
Nobody is going to say "flip it and cut half off each side" ? That was Milling 1A when I hit the Bridgeport for the first time.

You can't assume that anymore. A lot of people now started out on vmc's and think "Just put it in the machine and it does the rest !"Figured that went without saying.
Hi ,
.... while the workpiece is being clamp by precision vice.
An even thickness tolerance down to few thou is virtually impossible in a vice,
even with a vacuum table its hard nut to crack.

Alright, so I have a plate that started out as 19" x 13" x 1" AL6061. Finished part measures 0.540" thick. I took an equal amount of 0.230 off both sides. The first side I taped and super glued to a sub plate bolted down to bed of mill. Second side it was epoxy'd down around ouside edges and removed 0.15" then added 2 toe clamps in x axis. Then took the part to finished thickness plus 0.015". Part is now warped with center convex facing up. The bottom of the part has 3 pads and the top side has a small circular center pad with an outer ring both of which are 0.04" tall. The bottom side has a bunch of pockets for weight reduction.
Any way to prevent this next time? Part flexed one way after first side and now has gone the opposite but past our thickness tolerance. Any help or pointers would be great. TIA
