Differentiate between 2D and 3D design models. Discuss the specific applications of each type in various industries, and explain how each model contributes to product development and design validation. What is component modeling in the context of digital manufacturing? Discuss the importance of accurate component modeling and how it affects the overall manufacturing process. Outline the key factors to consider when selecting machines and tools for digital manufacturing. How do these factors influence the choice of equipment and its integration into the manufacturing process? Discuss the process of defining manufacturing processes and parameters. What are some examples of critical parameters, and how do they impact the quality and efficiency of the manufacturing output? What is tool path generation, and why is it crucial in digital manufacturing? Describe the process of creating tool paths and how they are optimized for different machining operations. Analyze the role of simulation in digital manufacturing. How does simulation contribute to the design and production stages, and what are its benefits in terms of risk reduction and cost savings? Compare and contrast the Thermo Jet Printer, Genisys XS Printer, JP System 5, and Object Quadra System. Discuss the technologies behind each system, their advantages, limitations, and typical applications in rapid prototyping.

Unit 2

1.Define and differentiate between Engineering Data Management (EDM) and Product Data Management (PDM). How do these components integrate within a Product Lifecycle Management (PLM) system? 2. Discuss the role of PLM in managing the lifecycle of a product from conception to disposal. How does PLM enhance the efficiency and effectiveness of product development processes? 3. Compare and contrast Product Lifecycle Management (PLM) and Engineering Resource Planning (ERP) systems. How do they address different aspects of the product development and manufacturing processes? 4. Analyze the characteristics of PLM systems such as singularity, cohesion, traceability, and the Information Mirroring Model. How do these characteristics contribute to effective product management? 5. Examine the impact of external drivers such as scale, complexity, cycle times, globalization, and regulation on PLM systems. How do these factors influence the design and implementation of PLM strategies? 6. Describe how PLM systems can be adapted to address the challenges of globalization. Provide examples of features or strategies within PLM systems that facilitate global collaboration and compliance. 7. Evaluate the importance of traceability within a PLM system. How does traceability affect decision-making, compliance, and quality management throughout the product lifecycle? 8. Explain the concept of the Information Mirroring Model in the context of PLM. How does this model enhance the management and utilization of product data? 9. Discuss the challenges and solutions associated with integrating PLM systems with other enterprise systems such as ERP and CRM. How can organizations ensure seamless data flow and interoperability? 10. Explore the relationship between PLM and Engineering Change Management (ECM). How do PLM systems facilitate effective management of engineering changes, and what are the benefits of this integration
