A medium carbon steel work–piece is turned on a lathe at 50 m/min cutting speed, 0.8 mm/rev feed and 1.5 mm depth of cut. What is the rate of metal removal ?
-
Solution
Rate of metal removal (Q) = VC × AP× fn
where, VC = cutting speed fn= feed rate,
AP= depth of cut Given : VC = 50 m/min, fn= 0.8 mm/rev,AP= 1.5 mm
Q= 50 × 1000 × 1.5 × 0.8 = 60,000 mm3/min.
