Manufacturing Practices (BT-106) - Important Questions

  1. Unit 17 Marks High Priority

    Define "manufacturing" and discuss the primary objectives of manufacturing. Classify manufacturing processes with suitable examples for each class.

    Core definitional and classification question; fundamental topic often asked as a short essay in Unit 1.

  2. Unit 17 Marks High Priority

    Explain different types of production systems: job production, batch production, mass production and continuous production. Compare these systems with respect to flexibility, unit cost and lead time.

    Standard comparative question on production systems; commonly asked to test understanding of production planning and organization.

  3. Unit 110 Marks High Priority

    Explain the mechanism of chip formation in orthogonal metal cutting. Classify chips and discuss factors affecting chip formation.

    Core metal-cutting theory question; tests conceptual understanding of chip formation and classification which is fundamental to machining topics in Unit 1.

  4. Unit 110 Marks High Priority

    Define cutting speed, feed and depth of cut. Derive the expression for material removal rate (MRR) in turning and show the formula

    $MRR = \frac{\pi D N f d}{1000}$

    where $D$ is diameter in mm, $N$ is spindle speed in rpm, $f$ is feed in mm/rev and $d$ is depth of cut in mm.

    Important quantitative relation frequently used in machining calculations; often appears in numerical problems or derivations.

  5. Unit 17 Marks High Priority

    Derive the expression for machining time for a turning operation to machine a length $L$ with feed per revolution $f$ and spindle speed $N$. Hence write the formula for machining time $t$.

    Basic time-estimation question used frequently in numerical sections; important for practical machining planning.

  6. Unit 17 Marks High Priority

    Define and explain the significance of tool geometry parameters: rake angle, clearance (relief) angle, cutting edge angle and nose radius. Discuss the effect of rake angle on cutting forces and chip formation.

    Standard conceptual question about tool geometry and its effects on cutting performance; often required in explanations and drawing-based answers.

  7. Unit 17 Marks Medium Priority

    Describe common tool materials used in metal cutting (such as high speed steel, cemented carbide, ceramics and cubic boron nitride). Discuss the selection criteria and the role of cutting fluids.

    Frequently asked topic assessing knowledge of tool materials and cutting fluids which is essential for selecting tooling in manufacturing.

  8. Unit 110 Marks High Priority

    Explain the relationship between cutting force, cutting speed and power in machining. Define specific cutting energy and show its relation to cutting force and cross-sectional area of cut.

    Core theoretical question on forces and energy in cutting; used to connect forces, power and specific cutting energy.

  9. Unit 17 Marks Medium Priority

    Define tolerance, allowance, limit of size, and explain the basic types of fits (clearance fit, transition fit and interference fit). Give examples of applications for each fit type.

    Measurement and metrology foundation question often included in Unit 1 to test understanding of limits and fits used in manufacturing.

  10. Unit 17 Marks Medium Priority

    Describe principal parts of a lathe machine and explain common turning operations such as facing, parting, threading and knurling.

    Machine-tool operations question testing understanding of lathe capabilities and commonly examined in Unit 1 practical theory.
