14. VIRTUAL PROTOTYPING AND TESTING TECHNOLOGY Geometric Modeling: The computer/software generated mathematical representation of an object’s geometry is called Geometric Modeling. As curves are easy to manipulate and bend as per application, geometric modeling uses curves extensively to construct surfaces. The formation of curves can be achieved by, a set of points, analytic functions, or other curves/functions.

15. VIRTUAL PROTOTYPING AND TESTING TECHNOLOGY Depending upon the representations of objects, geometric modeling system can be classified into three categories, which are: Solid modeling Wireframe modeling Surface modeling

16. VIRTUAL PROTOTYPING AND TESTING TECHNOLOGY Reverse Engineering: Reverse engineering is defined as the process of obtaining a geometric CAD model from 3-D points acquired by scanning/digitizing existing parts/products. The process of digitally capturing the physical entities of a component, referred to as reverse engineering (RE), is often defined by researchers with respect to their specific task.

19. PHYSICAL PROTOTYPING AND RAPID MANUFACTURING TECHNOLOGIES A physical prototype can be anything from a simple handmade model to a fully operational model representing how the conceptual design will correspond to real-world conditions. Physical RP builds tangible objects from computer data without the need of jigs or fixtures or NC programming.

20. PHYSICAL PROTOTYPING AND RAPID MANUFACTURING TECHNOLOGIES This technology has also been referred to as layer manufacturing, solid free-form fabrication, material addition manufacturing and three-dimensional printing.

21. PHYSICAL PROTOTYPING AND RAPID MANUFACTURING TECHNOLOGIES It involve rough visual and shape representations to fully functional physical prototypes. These can be created through traditional manual techniques, rapid prototyping or a combination of these processes.

24. PHYSICAL PROTOTYPING AND RAPID MANUFACTURING TECHNOLOGIES Computer Numerical Control: One of the reasons AM technology was originally developed was because CNC technology was not able to produce satisfactory output within the required time frames. CNC machining was slow, cumbersome, and difficult to operate. AM technology on the other hand was quite easy to set up with quick results, but had poor accuracy and limited material capability.

25. PHYSICAL PROTOTYPING AND RAPID MANUFACTURING TECHNOLOGIES The development of hybrid prototyping technologies, such as Space Puzzle Molding that use both high-speed CNC machining and additive techniques for making large, complex and durable molds and components.

26. PHYSICAL PROTOTYPING AND RAPID MANUFACTURING TECHNOLOGIES Robotics: Robotics is an  interdisciplinary  field that integrates  computer science  and  engineering. Robotics involves design, construction, operation, and use of  robots . The goal of robotics is to design machines that can help and assist humans.

27. PHYSICAL PROTOTYPING AND RAPID MANUFACTURING TECHNOLOGIES Robotics integrates fields of mechanical engineering, electrical engineering, information engineering, mechatronics, electronics, computer engineering, control engineering, among others.

28. PHYSICAL PROTOTYPING AND RAPID MANUFACTURING TECHNOLOGIES Computer Aided Process Planning: C omputer-aided process planning (CAPP) is the use of computer technology to aid in the process planning of a part or product, in manufacturing. CAPP is the link between  CAD  and  CAM  in that it provides for the planning of the process to be used in producing a designed part. Process planning is concerned with determining the sequence of individual manufacturing operations needed to produce a given part or product.

29. PHYSICAL PROTOTYPING AND RAPID MANUFACTURING TECHNOLOGIES Rapid prototyping: Rapid prototyping is the fast fabrication of a physical part, model or assembly using  3D computer aided design (CAD) . The creation of the part, model or assembly is usually completed using  additive manufacturing , or more commonly known as  3D printing . It includes a variety of manufacturing technologies, although most utilise layered additive manufacturing.

30. PHYSICAL PROTOTYPING AND RAPID MANUFACTURING TECHNOLOGIES However, other technologies used for RP include high-speed machining, casting, moulding and extruding. While additive manufacturing is the most common rapid prototyping process, other more conventional processes can also be used to create prototypes. These processes include: Subtractive manufacturing Compressive manufacturing

31. PHYSICAL PROTOTYPING AND RAPID MANUFACTURING TECHNOLOGIES Rapid Tooling: Rapid Tooling is when Rapid Prototyping techniques and conventional tooling practices are used together to produce a mold quickly. It is also used to prepare parts of a model from CAD data in less time and at a lower cost compared to traditional manufacturing methods. Rapid Tooling is used as a channel to produce injection molded parts.

35. SYNERGIC INTEGRATION TECHNOLOGIES

36. SYNERGIC INTEGRATION TECHNOLOGIES Concurrent Engineering: In concurrent engineering (CE) product is developed by a team involving engineers from both the design section and the production shop. The advantages of concurrent engineering are based on the economic leverage of addressing all aspects of design of a product as early as possible.

37. SYNERGIC INTEGRATION TECHNOLOGIES Hence using concurrent engineering most of the design modification is incorporated as early as possible. It is also true that the importance of early modification is very significant and the ability of the early change to influence the product cost is much larger as indicated.

38. SYNERGIC INTEGRATION TECHNOLOGIES Concurrent Engineering Process

39. SYNERGIC INTEGRATION TECHNOLOGIES Product Data Management: Product data management (PDM) is the technology and associated software systems that support the management of both engineering data and process information during the  product development phase  and beyond. PDM aims at providing product design teams with the right data and information at the right time for making proper design decisions.

40. SYNERGIC INTEGRATION TECHNOLOGIES

41. SYNERGIC INTEGRATION TECHNOLOGIES Computer Integrated Manufacturing: Computer-integrated manufacturing (CIM) refers to the use of computer-controlled machineries and automation systems in manufacturing products. CIM combines various technologies like computer-aided design (CAD) and computer-aided manufacturing (CAM) to provide an error-free manufacturing process that reduces manual labor and automates repetitive tasks.

42. SYNERGIC INTEGRATION TECHNOLOGIES CIM not only implies the use of computer in designing a product, planning inventory and production, controlling the operations and accomplishing many other designs, manufacturing, management and business related issues but suggest a marriage of the diverse functions under the control of one central supervisory computer.
