  • Technical Information: Forces and Power Requirements

  •  The forces in machining can be determined with a tool dynamometer.  In turning, the tool dynamometer usually measures three components:
    • Tangential, or cutting force
    • Thrust, or separating force
    • Feed, or axial force
  • The cutting force is important since, when multiplied by the cutting velocity, it determines the power requirements in titanium machining.  The thrust, or separating force, determines the accuracy produced on a part.

    For general approximations, the power requirements in turning and milling can be obtained by measuring the power input to the machine tool’s drive motor during a cutting operation and by subtracting from it the tare, or idle power.  A good approximation of the horsepower required in most machining operations can be predicted from unit power requirements.
