Radial Force This acts in a radial direction from the centerline of the work piece and is generally the smallest of the three, often about 50% as large as the longitudinal force Its effect on power requirements is very small because the velocity in the radial direction is negligible g = rake angle = a f = shear plane angle

Shear Angle Certain characteristics of continuous chips are determined by the shear angle The shear angle concerns the plane on which a slip occurs to begin chip formation Regardless of the shear angle, the compressive deformation caused by the tool force against the chip will cause the chip to be thicker and shorter than the layer of the work piece material removed The work or energy required to deform the material usually accounts for the largest portion of forces and power involved in a metal removing operation

Mechanics of Materials Cutting
To obtain an expression relating the shear plane angle f to the friction angle t and the rake angle g , we have constant FC = sin cos ( + ) By applying the principle of minimum energy,
