CAD/CAM /CIM (ME-704) - Important Questions

  1. Unit 514 Marks High Priority

    Explain the architecture of a typical Computer Integrated Manufacturing (CIM) cell. Describe each major component (CAD/CAM workstations, NC/CNC machines, PLCs, robots, automated material handling, inspection systems, communication network, and central database) and explain how they interact to accomplish integrated production.

    Core topic: Fundamental architecture and components of CIM cells; frequently examined concept in Unit 5 syllabi.

  2. Unit 510 Marks High Priority

    Draw and explain the data flow in a CIM system from product design to shop-floor execution. Include data exchange between CAD, CAPP, CAM, NC/DNC, PLCs, shop-floor monitoring, and enterprise systems (ERP/MRP).

    Core diagrammatic and descriptive question linking CAD/CAM and shop-floor dataflow — central to CIM understanding.

  3. Unit 57 Marks Medium Priority

    Discuss the advantages and limitations of remote CIM operation. Explain technical, economic, and managerial factors that influence the feasibility of operating manufacturing cells remotely.

    Directly addresses documented advantages/limitations of remote CIM operation and is a standard theoretical question in Unit 5.

  4. Unit 57 Marks Medium Priority

    What are Automated Guided Vehicles (AGVs)? Explain their components, navigation methods, control architecture, and typical applications in a CIM environment.

    Applied topic: AGV systems are common in CIM implementations; question tests knowledge of components and applications.

  5. Unit 514 Marks High Priority

    Explain a Flexible Manufacturing System (FMS). Describe its main elements, types of layouts (e.g. in-line, loop, ladder, and robot-centred), and discuss the benefits and limitations of FMS in modern manufacturing.

    High-value integrated question on FMS covering elements, layout options and benefits — core Unit 5 content.

  6. Unit 510 Marks Medium Priority

    Define Group Technology (GT) and Cellular Manufacturing. Explain methods for part-family formation (e.g. coding and classification, cluster analysis) and discuss the benefits of cellular layouts in a CIM context.

    Group technology and cellular manufacturing are key Unit 5 concepts linking production planning with CIM; commonly asked.

  7. Unit 510 Marks High Priority

    What is Computer-Aided Process Planning (CAPP)? Compare variant and generative CAPP and explain how CAPP integrates with CAD and CAM within a CIM framework. Include a brief data flow example.

    Integration of process planning with CAD/CAM/CIM is central to Unit 5; tests conceptual and practical understanding of CAPP.

  8. Unit 510 Marks Medium Priority

    Explain the role of shop-floor control systems (SFC) and their relationship with MRP/MRP II/ERP in a CIM environment. How does shop-floor feedback affect production planning and control?

    Shop-floor control and enterprise systems interface is important for CIM exams; tests system-level understanding.

  9. Unit 57 Marks Medium Priority

    List and describe key data exchange standards and communication interfaces used in CAD/CAM/CIM integration (for example, IGES, STEP, OPC, MTConnect, DNC). Explain why such standards are important.

    Standards and protocols are essential for integration; practical question addressing interoperability concerns in CIM.

  10. Unit 510 Marks Medium Priority

    Outline an implementation strategy for Computer Integrated Manufacturing in a medium-scale manufacturing firm. Discuss typical barriers to implementation and methods for economic justification including payback and ROI considerations.

    Strategy & economics question examining implementation issues — often asked to assess broader understanding of CIM adoption.

  11. Unit 57 Marks Low Priority

    Explain the role of industrial robots in a CIM environment. Classify robots by configuration and degree of freedom, and discuss common end-effectors and typical application tasks.

    Robotics within CIM is a practical topic; this question checks classification, capabilities and typical applications.

  12. Unit 514 Marks High Priority

    Prepare a step-by-step procedure to integrate a CAD model into CAM toolpath generation and deliver the NC program to a CNC machine via DNC in a CIM environment. Simulate the workflow and list possible causes of tool collision or part-fixture interference during execution.

    Applied integration question that mirrors typical exam patterns: CAD→CAM→CNC workflow and fault analysis in CIM.
