PART A

1 Testing of Molding sand and Core sand.

Preparation of sand specimens and conduction of the following tests:

1. Compression, Shear and Tensile tests on Universal Sand Testing Machine.

2. Permeability test

3. Sieve Analysis to find Grain Fineness Number (GFN) of Base Sand

4. Clay content determination on Base Sand.

Welding Practice:

Use of Arc welding tools and welding equipment

Preparation of welded joints using Arc Welding equipment

L-Joint, T-Joint, Butt joint, V-Joint, Lap joints on M.S. flats

PART B

2 Foundry Practice:

Use of foundry tools and other equipment for Preparation of molding sand mixture. Preparation of green sand molds kept ready for pouring in the following cases:

4. Using two molding boxes (hand cut molds).

5. Using patterns (Single piece pattern and Split pattern).

6. Incorporating core in the mold.(Core boxes).

• Preparation of one casting (Aluminium or cast iron-Demonstration only)

PART C

3 Forging Operations: Use of forging tools and other forging equipment.

• Calculation of length of the raw material required to prepare the model considering scale loss.

• Preparing minimum three forged models involving upsetting, drawing and bending operations.

Course Outcomes:

At the end of the course the student will be able to:

• Demonstrate various skills in preparation of molding sand for conducting tensile, shear and compression tests using Universal sand testing machine.
• Demonstrate skills in determining permeability, clay content and Grain Fineness Number of base sands.
• Demonstrate skills in preparation of forging models involving upsetting, drawing and bending operations.

Conduct of Practical Examination:

1. All laboratory experiments are to be included for practical examination.

2. Breakup of marks and the instructions printed on the cover page of answer script to be strictly adhered by the examiners.

3. Students can pick one experiment from the questions lot prepared by the examiners.

4. Change of experiment is allowed only once and 15% Marks allotted to the procedure part to be made zero.

Scheme of Examination:

1. One question is to be set from Part-A: 30 marks. (20 marks for sand testing+ 10 Marks for welding)

2. One question is to be set from either Part-B or Part-C: 50 Marks

3. Viva – Voce: 20 marks

Course Outcomes:

At the end of the course, the student will be able to:
