  1. Unit 110 Marks High Priority

    Explain the sand casting process in detail. Describe all major steps starting from pattern making to fettling and finishing. List common casting defects, their causes and remedies.

    Core topic from Unit 1. Fundamental casting process frequently examined; covers steps, tools and defects.

  2. Unit 17 Marks Medium Priority

    What are the materials used for patterns? Explain different types of patterns and discuss various pattern allowances such as shrinkage allowance, machining allowance and draft allowance.

    Basic concept from Unit 1 often asked to test understanding of pattern design and allowances.

  3. Unit 210 Marks High Priority

    Explain the principles of arc welding. Describe different types of arc welding processes, list important welding parameters and explain common welding defects with their causes and remedies.

    Core derivation from Unit 2. Arc welding theory, parameters and defects are repeatedly asked in exams.

  4. Unit 27 Marks Medium Priority

    Describe oxy-acetylene gas welding and cutting processes. Explain the equipment, flame types and safety precautions used in oxy-acetylene operations.

    Standard descriptive question from Unit 2 testing basics of gas welding and cutting.

  5. Unit 27 Marks Medium Priority

    Discuss TIG (GTAW) and MIG (GMAW) welding processes. Explain working principles, advantages, limitations and typical applications of each process. Compare TIG and MIG processes.

    Comparative conceptual question from Unit 2; commonly used to assess knowledge of modern welding processes.

  6. Unit 310 Marks High Priority

    Explain the working of a lathe machine. Describe various lathe operations and tool bit geometry. Discuss cutting parameters (cutting speed, feed and depth of cut) and factors affecting machinability.

    Core derivation from Unit 3. Lathe operations, tool geometry and cutting parameters are high-frequency exam topics.

  7. Unit 37 Marks High Priority

    Derive the expression for machining time in face milling and calculate the machining time if workpiece length is $L$, spindle speed is $N$ (rev/min), feed per tooth is $f_t$ (mm/tooth) and number of teeth on cutter is $z$. Use the formula $T = \left(\frac{L}{N\cdot f_t\cdot z}\right)$ and explain each term.

    Typical numerical and theory mix from Unit 3. Machining time formula and calculation are standard exam problems.

  8. Unit 37 Marks Medium Priority

    Explain grinding process and other surface finishing operations. Describe types of grinding wheels, grinding parameters and typical applications of surface finishing.

    Unit 3 topic testing surface finishing processes; asked occasionally to distinguish processes and applications.

  9. Unit 410 Marks Medium Priority

    Explain the rolling process for metal forming. Describe different types of rolling mills and derive expressions for rolling force and torque. Discuss defects in rolled products and their remedies.

    Core Unit 4 topic. Rolling and force calculations are standard long questions in manufacturing papers.

  10. Unit 47 Marks Medium Priority

    Explain forging and extrusion processes. Discuss their classifications, process parameters, advantages, limitations and typical industrial applications. Highlight differences between forging and extrusion.

    Standard conceptual question from Unit 4 covering common forming processes frequently included in syllabi.

  11. Unit 514 Marks High Priority

    Explain various heat treatment processes of steels including annealing, normalizing, hardening and tempering. Draw and explain a typical TTT diagram for steel and describe the Jominy end-quench test for hardenability.

    Core and high-weight Unit 5 topic. Heat treatment theory, TTT and Jominy tests are highly important and repeatedly asked.

  12. Unit 57 Marks Medium Priority

    Describe common non-destructive testing (NDT) methods such as ultrasonic testing, radiographic testing and dye penetrant testing. Discuss principles, equipment and typical applications of each.

    Standard Unit 5 topic. NDT methods and inspection are common short questions testing quality control knowledge.

  13. Unit 57 Marks Low Priority

    Explain the steps involved in powder metallurgy. Describe powder production, compaction, sintering and finishing processes, and mention typical applications of powder metallurgy products.

    Optional Unit 5 topic; less frequently asked but part of modern manufacturing syllabus.
