Exercises 4 1. A 30 mm diameter mild steel bar is being turned at a spindle speed of 8 rev/s, on a multi-tool centre lathe having eight tools in operation. The feed is 0-3 mm/rev, the specific cutting pressure/tool is 2 000N/mm and the total power consumed for the operation is 14 kW. If the depth of cut is to be kept the same for each tool, calculate the depth of cut/tool in mm.
Q1. Calculate the time required to machine a workpiece 170 mm long, 60 mm diameter to 165 mm long 50 mm diameter. The workpiece rotates at 440 rpm, feed is 0.3 mm/rev and maximum depth of cut is 2 mm. Assume total approach and overtravel distance as 5 mm for turning operation. Answer Q2. A gray cast iron surface 280 wide and 540mm long may be machined either on a vertical milling machine, using a 100mm - diameter face mill having eight inserted HSS teeth, or on a horizontal milling machine using an HSS slab mill with eight teeth on a 200-mm. diameter. Which machine has the faster cutting time? The values of feed per tooth and cutting speed for both processes are 0.4mm/tooth and 80m/min, respectively. The depth of cut = 3.0 mm and assume A and O equal to 5. Answer
