by which the face of the tool is inclined towards back
by which the face of the tool is inclined sideways
between the surface of the flank immediately below the point and a plane at right angles to the centre line of the point of tool
between the surface of the flank immediately below the point and a line drawn from the point perpendicular to the base
increases tool life
decreases tool life
produces chipping and decreases tool life
results in excessive stress concentration and greater heat generation
The larger side rake angle produces chipping
The smaller rake angle produces excessive wear and deformation in tool
The side cutting edge angle (less than 15 degree) increases tool life
The increase in nose radius decreases tool life.
