16.1 A cylindrical workpart 200 mm in diameter and 700 mm long is to be turned in an engine lathe. Cutting speed = 2.30 m/s, feed = 0.32 mm/rev, and depth of cut = 1.80 mm. Determine (a) cutting time, and (b) metal removal rate. Solution: (a) N = v/(πD) = (2.30 m/s)/0.200π = 3.66 rev/s f r = Nf = 6.366(.3) = 1.17 mm/s T m = L/f r = 700/1.17 = 598 s = 9.96 min Alternative calculation using Eq

Example 1: A round pipe has a diameter of 25 mm and water is running through it with a velocity of 10 m/s. What is the flow rate of the water? First, we calculate the crosssection area to be (25/2)^2 · 3. ~= 490.875 mm 2. We can convert this to m 2 by dividing by 1,000,000 for more convenient results, getting 0. m 2.
