(ii) What is the measure of metal removing process machinability? What are the factors that affect it?
2. (i) Explain the types of chip formed during machining process.
(ii) List the various types of tool wear and discuss the factors affecting them.
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.
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.
