Question Paper
Describe Investment casting process. Also discuss its advantages and disadvantages.
Briefly describe with neat sketches, the processes and applications of
Die casting
Centrifugal casting.
2. Calculate the size of a cylindrical riser with i h ratio necessary to feed a steel slab casting 25 x 25 x 5 cm^3. Assume the volume shrinkage on solidification is for steel and that the volume of riser is three times that dictated by shrinkage consideration alone.
Describe the desirable properties of a mould sand and state what defects can arise due to absence/lack of these desirable properties. Also mention other casting defects possible.
Sketch and briefly describe the working of Cupola furnace.
Discuss the various defects in deep drawing operation. Also list the various factors on which these defects depend.
Briefly describe the process for bending a strip making allowance for its spring back.
5. A symmetrical cup of circular cross-section with diameter 52 mm and height 52 mm, and a corner radius of 2 mm is to be obtained in C 20 steel of 0·8 mm thickness. Make the necessary calculation for designing the die for the above cup.
Discuss the welding characteristics of Grey Cast Iron.
Explain the difficulties which may be encountered in the welding of high thermal conductivity materials.
What are the various thermo-chemical welding processes? Explain the working principle of thermit welding with the help of a neat sketch.
What are the various radiant energy welding processes Explain the working principle of electron beam welding with the help of a neat diagram.
What are the different welding defects obtained during welding Explain the various factors on which these welding defects are encountered.
Write a short note on MIG welding.
Explain Merchant's circle diagram and derive the expression for different cutting forces.
Write a short note on Economics of machining.
10. In an orthogonal cutting test on a mild steel tube of size 150 mm diameter and 2·1 mm thickness, conducted at 90 metres per minute and 0·21 mm/rev. feed, the following data were recorded:
Cutting force 1250 kgf
Feed force 30 kgf
Chip thickness 0·3 mm
Contact length 0·75 mm
Net Horse power kW
Back rake
Calculate shear, strain and strain energy per unit volume.
