Plate 200 mm x 90 mm is to be maintained on a shaper under following condition, v= 13.5 m/ min
Feed is 0.57 mm/ double stroke, Approach and overtravel 20 mm each in longitudinal direction and 4
mm each in lateral direction. The ratio of cutting to the return speed is 0.83.Calculate the machining
time in minutes?
A turning operation uses a 2/64 in nose radius cuttingtool on a free machining steel with a feed rate = 0.010in/rev and a cutting speed of 300 ft/min. Determine thesurface roughness for this cut.
In turning of stales steel alloy, 1100 mm length and 400 mm diameter, the Feed was 0.35 mm/rev, and depth
of cut = 2.5 mm. The tool used in this cutting is cemented carbide tool where Taylor tool life parameters are n
= 0.24 and C = 450 (tool life (min) and cutting speed (m/min). Compute the cutting speed that will allow the
tool life to be 10% longer than the machining time for this part.
