Question 3: (i) Define the various tool parts of a single point cutting tool with a neat sketch.
(ii) What are the standard angles of cutting tool? Explain in detail.
Question 4: (i) Explain the essential characteristics of a cutting fluid.
(ii) The following equation for tool life is given for a turning operation; V T 0.13 f 0.77 d 0.37 = C, A 60 minute tool life was obtained while cutting at V=30 m/min, f=0.3 mm/rev and d=2.5mm. Determine the change in tool life if the cutting speed, feed and depth of cut
