      How to calculate gripping force on collet.

      The collet dimensions: Dia 70mmx16mm
      Power Chuck Dia 250mm (Jaw=3)
      Special Jaws, overhang of jaw: 119mm
      Static gripping force: 10630N
      The Chuck is held on rotatory table.
      Operation: machining grooves on round part

      Any suggestions?

      Thank you

      There are many other dynamic forces that need to be considered........ In the machining of parts we are concerned about chip loads, and worry more about that than how much force to apply to a tool.

      chip load can be calculated by Feed rate / rpm * # of flutes
