keep a 13" x 13" x 3/16" plate flat? | |
I have a set of 13"x13"x3/16" Aluminum 6061-T6 plate i am making into chessboards. My question is how to get the board reliably flat on the mill table preferably using only strap clamps. The table is about 10" in the Y so i can only clamp on 2 sides reliably.
The machining i am doing is a series of pockets that is every other square (im assuming you guys know what a chess / checkers board looks like) that is 0.010" deep on a grid 12"x12". Then i am doing some engraving on the sides of the board. So the finished product has a series of 1.5x1.5 pocketed squares and then some engraving on the sides.
The pattern on the boards has a 0.5" border i can clamp onto or i could clamp inside one of the squares not getting milled although ill have to check the collet clearances. I would like to do as much machining as possible on a single clamping.
How or better yet WHERE would you put clamps to hold this plate as flat as possible and also minimize the number of times the clamps need to be removed and repositioned.
