    The aim of this section is to determine the forces applied by the tool to the workpiece attached to the spindle during a turning operation (figure 1 ).

    p : infeed depth (mm)

    γ : orthogonal cutting angle

    f : feed rate (mm/rev)

    α: orthogonal draft angle

    h : cutting thickness (mm)

    r ∊; : tool nose radius (mm)

    b : cutting width (mm)

    κ r : edge direction angle
