Machining time required reduce a mild steel rod of diameter 60mm, initial length (L) 125mm to final length (L1) 120mm to 58 mm by turning a carbide insert. If the approach length and over run length are 5 mm and 1 mm respectively, take Cutting speed as 20 m/min and feed is =0.2 mm/rev, and the depth of cut is 0.5mm
