    Study Notes

    Advantages of CAPP

    • Systematic development of accurate and consistent process plans
    • Reduced cost and lead time of process planning
    • Increased productivity and reduced skill requirements for process planners
    • Can interface with higher-level applications like cost estimation and work standards

    Approaches to CAPP

    • Retrieval/Variant: uses principles of GT and Parts Classification & Coding to select and edit generic process plans for specific part families
    • Generative: creates process plans from scratch without human intervention using decision logic, formulas, algorithms, and geometry-based data

    Quality Control (QC)

    • Traditional Methods: Manual inspection and statistical sampling
    • Objectives of CAQC: improve product quality, increase productivity in inspection, and reduce lead-time and wastage

    Role of Computers in QC

    • Computer-Aided Inspection (CAI) and Computer-Aided Testing (CAT): performed automatically using computers and sensors, integrated into CIM systems

    Inspection Methods

    • Contact Method: uses mechanical probes, widely used in manufacturing for metal parts and electrical circuit testing
    • Non-Contact Method: eliminates need for workpiece repositioning, faster and avoids mechanical wear and surface damage
    • Examples of Non-Contact Devices: Intelligent robots with computer vision and sensors for automated test cells, Coordinate Measuring Machine (CMM)

    Coordinate Measuring Machine (CMM)

    • Structure: table and movable head with a sensing probe, controlled by CNC
    • Types: Cantilever, Bridge, Column, Gantry, Horizontal

    Advantages of Non-Contact Inspection

    • No need to reposition the workpiece
    • Faster than contact inspection
    • No mechanical wear or part surface damage

    Group Technology (GT)

    • Philosophy: group parts based on similarities in design or manufacturing processes to reduce overall manufacturing costs
    • Part Families: grouped by geometry or processing methods

    Communications Standards

    • Need: improve communication and efficiency in manufacturing with standards like ISO/OSI reference model

    Artificial Intelligence (AI) in Manufacturing

    • Definition: systems exhibiting human-like intelligence (learning, reasoning, problem-solving)
    • Goal: simulate human behaviors on computers
    • Application: knowledge engineering to solve application problems
    • Technologies: artificial intelligence in CAD software, cloud-based software, digital twin, model-based definition, virtual reality (VR), augmented reality (AR), industrial Internet of Things (IIoT), robotics, industrial automation, 3D printing/additive manufacturing

    Questions and Answers

    • Primary function of CAD: define the design geometry for architectural structures, mechanical parts, building layouts, or electronic circuits
    • Main components of CAD hardware: computer, graphics display terminals, keyboards, and other equipment
    • Advantages of using CAD software: detailed and precise designs, easier modifications, cost estimation on the design itself
    • Main goal of CAM: automate, assist, and control various manufacturing processes using computer software and hardware technologies
    • Difference between direct and indirect CAM systems: direct CAM systems involve computer monitoring and controlling the manufacturing process directly, while indirect CAM systems do not
    • Concept of Kanban: visual system for controlling production quantities and timing, ensuring production matches customer demand, and preventing overproduction and reducing waste
    • Basic types of topology for a LAN: star, ring, and bus topology
    • Contribution of AI to manufacturing: simulating human behaviors, automating and optimizing complex manufacturing tasks, and improving decision-making processes
    • New trends in CAD/CAE/CAM technologies: cloud-based software, digital twin technology, virtual reality (VR) and augmented reality (AR)
    • Lean manufacturing: systematic approach to identifying and eliminating waste in every area of manufacturing through continuous improvement, focusing on maintaining productivity by emphasizing product flow in a pull system and reducing non-value-added activities
