Trying to determine if a specific rotary table is going to work as a 4th axis for me. Holding torque is the concern. Is there a way to estimate cutting forces from an endmill? I'm milling mostly 7075 aluminum using a carbide 3 flute 37 degree helix endmill, usually rough at 10mm depth, 1mm stepover, 13k rpm, 1500mm/m feed. I need to know what kind of forces are going to act on the stock. Any way to ballpark estimate this?
