The following observations were made during an orthogonal cutting operation:
Tool rake angle ......... 10°
Co-efficient of friction ......... 0.85
Chip thickness ......... 2.5 mm
Width of cut ......... 15 mm
Cutting speed ......... 40 m/min
Depth of cut ......... 1.5 mm
Shear strength ......... 650 N/mm2
Determine the following:
(i) Chip thickness ratio.
(ii) Shear angle.
(iii) Shearing force.
(iv) Friction angle.
(v) Cutting force.
(vi) Power consumed at the cutting tool.
