Doing design work for a punch press for rubber walk mat coping. I will be punching 1/2 inch square along the edge of an extruded rubber core. The slots with be 1 inch center to center. Punch press is a simple die shoe with cutting dies attached. My question is what would be the best linear feed mechanism to maintain an accurate 1 in center to center on my cutouts? Would a pressure roll driven by the press do the job if so any diagrams that would help in the design? Without getting elaborate and over budget is there a servo drive or encoder that would be better? Thanks billbwi
