I am investigating a manufacturing process in our shop where we are cold forming (pressing) the countersink detail into the plate rather than machining it. The countersink is for a 3/4" bolt and a 3/4" plate. Problem is the plate is splitting to the end of the plate which is 1.625" from the end of the plate to the center of the hole. The material is a 50ksi yield plate.
Do any of you have any tips or tricks to correct this issue? It may be that we are just asking for too much and to get there is just overstressing the plate.
Thanks in Advance!
