Note: Question no. 1 is compulsory. Answer any four from questions no. 2 to 7. Use of calculator is allowed. Assume any suitable data, if missing.

1. In an orthogonal cutting process, the following observations were made:
Depth of cut 0.25 mm, chip thickness ratio =0.45, width of cut mm, cutting velocity 40 m/min, cutting force component parallel to cutting velocity vector 1150 Feed force 140 rake angle of the tool =18°.

Determine the resultant cutting force, power of cutting, shear angle, friction angle and force component parallel to shear plane.

Estimate the blanking force to cut a blank. 25 mm wide and 30 mm long from a 1.5 mm thick metal strip, if the ultimate shear stress of the material is 450 N/mm2• Also determine the work done, if the percentage penetration is 25% of material thickness. 7

2. Compare Cold-chamber and Hot-chamber methods of die casting. 7

List the types of furnaces used in casting. Discuss the various types of ladles used in a foundry. 7

3. Explain the function of a pattern in the casting process. Discuss the difference between loose piece pattern and split pattern. 7

Give the composition of a typical green moulding sand. Discuss the various binders used in moulding sand. 7

4. List the essential characteristics of a cutting fluid. Which coolants would you suggest for turning of the following metals with HSS tools? 7

Cast iron

Bronze

Alloy steels


Why were cutting tool inserts developed Discuss the two methods of attaching inserts to tool shanks. 7

5. With the help of neat sketches, explain the following welding methods: 7

Upset butt welding

Flash butt welding

Describe in brief the 'oxy-acetylene flame cutting'. How does the cutting flame tip differ from a welding flame tip 7

6. Differentiate between hot and cold working of metals. Write the advantages and disadvantages of these techniques. 7

Discuss the various types of chips produced during metal machining. What is the use of a Chip Breaker? 7

7. Write short notes on any four of the following:

Pressurised and Unpressurised Gating Systems

Welding Defects

Tool Signature

Crater and Flank Wear

Bending Methods

Punch and Die Wear in Drawing Operation
