  1. Unit 16 Marks Medium Priority

    Define manufacturing. Explain classification of manufacturing processes with suitable examples for each class (e.g., forming, casting, machining, joining, additive manufacturing).

    Fundamental definition and classification; core concept of Unit 1.

  2. Unit 14 Marks Medium Priority

    Explain the importance of workshop safety. List and describe general safety practices and the commonly used personal protective equipment (PPE) in a manufacturing workshop.

    Safety practices and personal protective equipment (PPE) are essential in workshops; conceptual and descriptive question.

  3. Unit 110 Marks Medium Priority

    Describe different types of production systems: job production, batch production, mass production and continuous production. Discuss typical applications, advantages and disadvantages of each system.

    Standard comparative question on production systems often asked to test understanding of manufacturing organisation.

  4. Unit 18 Marks Medium Priority

    Describe the principles, construction and use of the vernier caliper and the micrometer. Explain how to determine the least count of each instrument and illustrate with an example reading.

    Measurement instruments are core to practical workshops; question may include least count and usage.

  5. Unit 17 Marks Medium Priority

    Draw and label the layout of a typical small-scale engineering workshop showing sections for lathe, milling, drilling, welding, foundry and inspection. Explain the rationale for the placement of these sections.

    Diagrammatic/layout question reflecting workshop planning and spatial organisation; tests ability to present labelled layouts.

  6. Unit 14 Marks Medium Priority

    What are the basic safety signs used in industry? Explain the standard color coding used for safety signs and hazard communication in workshops.

    Safety signage and color coding are basic MCQ/short answer topics frequently included in Unit 1.

  7. Unit 16 Marks Medium Priority

    A workpiece of diameter $D=150\ \text{mm}$ is machined on a lathe at spindle speed $N=300\ \text{rev/min}$. Calculate the cutting speed $v$ in m/min using the formula $$v = \frac{\pi D N}{1000}$$ Show all steps and the final answer.

    Typical numerical problem on machining parameters used to test calculation skills.

  8. Unit 110 Marks Medium Priority

    Explain the sand casting process. Describe the main steps involved in sand casting, types of patterns used and common casting defects with their causes and remedies.

    Core process question on sand casting and defects; frequently asked in foundational units.

  9. Unit 18 Marks Medium Priority

    Describe the working principles and applications of the following welding processes: Shielded Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW/MIG), and Tungsten Inert Gas (TIG) welding. Compare them in terms of heat source, filler material, shielding arrangement and typical applications.

    Comparative description of common welding methods; a typical short essay question.

  10. Unit 16 Marks Medium Priority

    Explain the concept of quality control in manufacturing practices. Describe basic inspection methods used in workshops and list common non-destructive testing (NDT) techniques with brief purpose of each.

    Quality control and inspection basics are foundational and often asked as short/long answer.
