  16. INPUT ` Money - Working Capital (Money for employee) • Fixed Capital (For machine tools and buildings) Lecturer: Dr. HABEEB ALANI

  17. INPUT Energy - Electricity To run the machines - Compressed airTo run the pneumatic systems and clean machines and products - Steam To run the turbines and utilized in produce of polystyrene (Expansion OP.) - Gas To use it in Furness, welding operations and boilers. Lecturer: Dr. HABEEB ALANI

  18. PROCESS Design - Creating plans for new products • Lowering the product cost at maintained high quality Lecturer: Dr. HABEEB ALANI

  19. PROCESS Production - Designated at the design stage - Machine tools types - Machining processes - People are selected at the design stage Lecturer: Dr. HABEEB ALANI

  20. OUTPUT Products Goods - Consumers goods: People use them (Food, Cars, ….) - Capital goods: Products used to make other consumer goods (Machine tools, Plant, ….) Lecturer: Dr. HABEEB ALANI

  21. TheClassification of basic Manufacturing 1-2 Job-lot Mass production Moderate a b c Lecturer: Dr. HABEEB ALANI

  22. Mass Production Features: a - Goods are produced at a high volume for considerable period of time ( >100.000 parts per year). - Machine are not flexible (They are not able to produce other types of products). - Products of this type of mfg are the cheapest. Lecturer: Dr. HABEEB ALANI

  23. Moderate production Features: b - Variable products (depends on the sale order and the market demand) (2,500-100,000 parts per year). - Multipurpose machine tools and CNC machine tools are usually used in this type of mfg. - Product Ex.: Tools, Moulds, Radio transmitters. Lecturer: Dr. HABEEB ALANI

  24. Job-lot production Features: c - The plant does not any specific type of products but it is able to produce any type of product that the market is in need of. - Products move in lots between mfg processes (10-500 parts per lot). - Machine are more flexible and universal. - Product Ex: Airplanes, Automobile parts, and Plastic products . Lecturer: Dr. HABEEB ALANI

  25. Organization for Manufacturing -A plant needs an affective organizing method for manufacturing in order to manage its resources / Employees Money Power Materials Machines . *A good mfg strategy is needed. 1 2 3 4 5 Lecturer: Dr. HABEEB ALANI

  26. Concurrent Engineering CE • It is a philosophy that promotes interactive design and manufacturing efforts to develop product and processes . CE is not an engineering discipline.- CE Objective: Optimizing the use of companyresources and reducing time to market cycle. Lecturer: Dr. HABEEB ALANI

  27. General CE phases for a new project: Technology and concept development Ph.-1 Product and Process Development and Prototype validation -CE Function Ph.-2 Process Validation and Product Design Confirmation Ph.-3 Production and continuous improvement Ph.-4 Lecturer: Dr. HABEEB ALANI

  28. Design, Material and Production 1-3 • According to the existing machine tools and the designed product we choose the raw materials. On the other hands, according to the existing materials and required quality we choose the machine tools. Lecturer: Dr. HABEEB ALANI

  29. - Efficiency of production : • In order to attain a high production rate with a low labor cost, Automatic features have been built gradually in different machine tools. Nowadays we deal with fully automatic machine tools and computer aided design and manufacturing (CAD/CAM). But the problem is that maintenance of such automatic machines is very expensive. Lecturer: Dr. HABEEB ALANI

  30. Cont….. Efficiency of production • The quality and accuracy must be maintained for the whole mfg processes so at the output we produce parts that can be quickly assembled (interchangeable). Lecturer: Dr. HABEEB ALANI

  31. - Economical production is determined by: A functional simple design that has appropriate quality (no more or less). 1 A material choice that represents the best compromise among physical properties, cost, and machinability. 2 The selection of mfg processes that provide the plant with required quality and accuracy (no more accuracy than necessary) at the lowest possible cost. 3 Lecturer: Dr. HABEEB ALANI

  32. Engineering Materials Materials Metallic Non-Metallic Ferrous Organic Non-Ferrous Non- Organic Lecturer: Dr. HABEEB ALANI

  33. Materials Application Chain Processing * SELECTION is the Critical Step for Technologists. Structure Properties Performance Selection Field Application Lecturer: Dr. HABEEB ALANI

  34. Mechanical Properties • Stress & Strain • Dislocations & Deformation • Elasticity & Plasticity Lecturer: Dr. HABEEB ALANI

  35. Tests • Mechanical Testing • Mechanical Properties • Strengthening Mechanisms • Failure Analysis Lecturer: Dr. HABEEB ALANI

  36. The Evolution of Materials Lecturer: Dr. HABEEB ALANI

  37. Classes of Materials Basic Metals Ceramics Polymers Advanced Biomaterials Semiconductors Composites Lecturer: Dr. HABEEB ALANI

  38. Metals • Materials that are normally combinations of "metallic elements". • Metals usually are good conductors of heat and electricity. • Metals are quite strong but malleable and tend to have a lustrous look when polished Lecturer: Dr. HABEEB ALANI

  39. Ceramics • Ceramics are generally compounds between Metallic and NONmetallic elements and include such compounds as: -Oxides -Nitrides -Carbides Ceramic materials developed for gas turbine rotors are used in aircraft and diesel engine parts. • Typically they are insulating and resistant to high temperatures and harsh environments. Lecturer: Dr. HABEEB ALANI

  40. Plastics • Plastics (or polymers) are generally compounds based upon carbon and hydrogen (Organic Compounds). • They are very large molecular structures. • Usually they are low density and are not stable at high temperatures. Using advanced polymer materials, organic light emitting diode (OLEDs) displays produce bright, high-contrast display panels with a wide viewing angle. OLED panels are emissive, eliminating the need for the backlight required in display technologies such as liquid crystal displays (LCDs). Lecturer: Dr. HABEEB ALANI

  41. Semiconductors • SEMIconductors have electrical properties intermediate between Metallic conductors and Ceramic insulators. • Also, the electrical properties are strongly dependent upon small amounts of Impurities. Lecturer: Dr. HABEEB ALANI

  42. Composites • Composites consist of more than one material type. • Fiberglass, a combination of glass and a polymer, is an example. Concrete and plywood are other familiar composites. • Many new combinations include ceramic fibers in a metal or polymer matrix. Lecturer: Dr. HABEEB ALANI

  43. Composites Lecturer: Dr. HABEEB ALANI

  44. Composites Hand bag Ghost airplane Graphite MatrixComposite Shaft Liquid MetalFacePlate Golf Clubs Lecturer: Dr. HABEEB ALANI

  45. BioMaterials • Materials compatible with an organism (e.g. Humans) that can be used to make implants, prostheses, and surgical instruments. • Designed not to provoke rejection by our bodies (skin, blood, bone, etc.), they can be natural (collagen, cellulose, etc.) or synthetic (metallic, alloy, ceramic, plastic, and others). • Dental crowns and contact-lenses use biomaterials.

  48. Data capture Economic analysis and business case $ Test data Test Successful applications Selection and implementation Characterization Materials Information for Design The goal of design: “To create products that perform their function effectively, safely, at acceptable cost” What do we need to know about materials to do this? More than just test data. Stat/Math analysis Selection of material and process Potential applications Design data Lecturer: Dr. HABEEB ALANI
