  1. Introduction to Digital Manufacturing Part 1: An Overview of the Digital Manufacturing Vukica Jovanovic Mechanical Engineering Technology

  2. Digital Manufacturing: DefineBasic Parts Unit 3

  3. CAD: Computer-Aided Design • The use of computer technology to aid in the design of a product • 2D vector base drafting systems • 3D solid and surface modelers

  4. CAD Software • Animation • AutoCAD Add-ons – Mechanical • Parts and Details • MCAD Programs • Sheet Metal Design • Specialized MCAD Programs • Surface Modeling • Tolerance Analysis • Viewers • Virtual Prototyping

  5. CAM: Computer-Aided Manufacturing • Typical areas of concern: • High Speed Machining: streamlining of tool paths • Multi-function Machining • 5 Axis Machining Mold and Tooling Example Tool path generation

  6. CAPP: Computer Aided Process Planning • To prepare: • Detailed set of plans • Instructions to produce a part • Begins with • Engineering drawings • Specifications • Parts or material lists • Forecast of demand • The results of the planning are: • Routings • Process plans • Fabrication & assembly drawings

  7. Factory Layout Planning • Creation of layout from 3D models for: • Virtual 3D models: sales personnel • Photo-realistic images or animation • Potential customers • BOM: basis for price calculations

  8. Ergonomics • Design tasks and work areas • Maximize the efficiency and quality of employees’ work • To enhance user safety and comfort • To improve the ergonomics of product designs

  9. Off-line Robot Programming • Takes place on a computer • Models of the workcell: • robot, pieces and surroundings • Reuse of existing CAD data • The robot programs are verified in simulation • Errors are corrected

  10. Production Process Simulation • Define problems & identify bottlenecks • Validation of proposed implementations under time constraints • Capacity Planning • Lead time reduction • Work in progress reduction

  11. Product Lifecycle Management Systems • The process of managing the entire lifecycle • From its conception • Through design and manufacture • To service and disposal

  13. PLM Information Model

  14. Analysis Software: Finite Element Analysis (FEA) • Computer simulation technique used in engineering analysis • Numerical technique • Based on an energy principle such as • The virtual work principle or • The minimum total potential energy principle • Leading products • ANSYS • ABAQUS • LUSAS • LS-DYNA • NASTRAN • SAMCEF
