For the last few years Team 2451, Pwnage, has been using 1"x1"x.04" VersaFrame Tubing to build our chassis. Last year one of our alumni (current mentor) converted an existing fixture to speed the cutting process and increase the precision of cutting the VersaFrame tubing to size. During the offseason he has designed and manufactured a brand new cutting fixture. This fixture is installed in a Curt Vise in a Bridgeport mill. A horizontal head attachment is used to drive the slitting saw blade in a vertical orientation. The finer the toothed blade the less likely the thin wall tubing will be bent during cutting. The angle of the cut is adjustable and graduated marks are provided for quick adjustment. The tube is positioned in the correct location using a precision pin inserted through the existing VersaFrame mounting holes which engages a precision reamed hole in the fixture. This allows for a single value to be changed in the Prototrak 2D CNC controller, the angle to be adjusted (if needed) and the blade to cut the tube to the correct length.
