1. Tool actions on the spindle

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
