The following data relate to orthogonal cutting of mild steel part:
Cutting speed ......... 195 m/min
Tool rake angle ......... 12°
Width of cut ......... 1.75 mm
Uncut thickness ......... 0.25 mm
Average coefficient of friction between the tool and chip ......... 0.52
Shear stress of work material ......... 385 N/mm2
Calculate:
(i) Shear angle.
(ii) Cutting and thrust components of the machining force
