11. A hole of 12mm and 25 mm depth is to be drilled using an HSS drill for a medium carbon steel. For average metal cutting conditions, determine: (i) suitable speeds (rpm) and feeds (mmrev); (ii) the time to machine the hole. #80 18. Using the data in Table Q6.18 and the drawing in Fig. Q6.18, determine suitable speeds (rev min) and feeds (mm rev) and the total machin- ing time for all operations listed. The raw material billet is 085x250mm and the machining allowance to be used is 5 mm.
