Is there a mathematical method or reference source/handbook for computing the compressive forces necessary for thread rolling? I realize I could use FEM, but that is a lot of work, so I am hoping to avoid it if at all possible.
I am designing a frame that will hold two parallel radial rolls and gearing to drive the rolls into the workpiece while rotating and I need to know the approximate forces involved so I can (1) dimension the frame to be strong and rigid enough, and (2) accommodate appropriate gearing.
The variables are the material being rolled (typically annealed alloy steel or stainless steel), the diameter of the material (expected to be between 1/4" and 3/4") and the thread pitch. The type of thread is Acme.
I am not asking for an answer that computes the compressive force. I am looking for an answer that tells me how to do the computation myself, or at least explains the theory.
I know I can go to LMT Fette and they can just tell me off the bat, but I would rather not be going hat-in-hand to vendors every time I need to solve a problem.
