Understanding tangential cutting force when milling ,

May 01, 2012· Torque (T s) that is applied to the spindle, and therefore to the milling cutter, is generated by the tangential cutting force (F t) and can be calculated by the formula: T s = F t × R (1) Where R is a radius of a milling cutter (Formulas are referenced later by the number in parenthes) The concept of calculating tangential cutting force ....

Tom's Techniques – Reference

The nose radius should be kept around 1/64″ for steel and 1/32″ or so for non ferrous metals If it’s too small, it will burn out quickly on steel, too large and it will chatter Fly cutters dissipate heat better than end mills, so I generally run them 30%-50% faster than an end mill of equal size...
