17. Day 1

18. Production Tools Used in FOT

19. Processing • The human ability to design and use tools provides the foundation for technology. • Three major types of processing: • Material processing. • For example, changing lumber into plywood. • Energy processing. • Changing flowing water into hydroelectricity. • Information processing. • Telecommunications, printing, and the computer.

20. Machine Tools • The world around us is full of artifacts made through material-processing. • Fundamental to all material-processing is a group of tools calledmachine tools. • Machine tools have some common characteristics like acutting tool, a method of moving the tool or workpiece, and a method of supporting the tool and the workpiece.

21. The Cutting Tool • Share common requirements shown in image to right. • Two basic types:single-point toolormultiple-point tool. • Single-point tools: hand tools, lathe-turning tools. • Multiple-point tools: abrasive papers, grinding wheels.

22. Motion • All cutting operations have two basic motions:cutting motionandfeed motion. • Three cutting motions: • Rotating motion. • Linear motion. • Reciprocating motion.

23. Support • The types of cutting and feed motions used determine the support system needed. • Different parts such aschucks, arbors, clamps, and machine tables can be used to provide support. • Most parts support different movements and can be combined in different ways, depending on what support is needed.

24. Types of Machine Tools • Hundreds of different machine tools exist. • All machine tools can be grouped into six categories, however.

25. Turning Machines • Turning machines use a process in which a workpiece is held and rotated on an axis. • Lathes, a form of turning machines, are used primarily to machine wood and metal. • All lathes contain four main parts: headstock, tailstock, bed, and tool rest or holder. • Lathes are used to perform turning, tapering, facing, grooving, chamfering, parting, threading, and knurling.

26. Sawing Machines • Sawing machines are designed to perform a number of different cutting actions, as shown in the image. • The machines can be grouped into three basic types of saws:circular saws, band saws, andscroll saws.

27. Circular Saws • Blade in the shape of a disk with teeth around the edge. • Used for crosscutting, ripping, and combination cutting. • Three basic types:table saw, radial saw, and chop saw.

28. Band and Scroll Saws • Band saws use a blade with teeth on one or both sides. • The band may be either vertical or horizontal and may be held by vises and clamps or placed on a table. • Scroll saws have teeth on just one edge of the blade and can also be either vertical or horizontal. • They are supported primarily by a table.

29. Drilling Machines • Cylindrical holes are common in parts and products. • They can be produced by various drilling machines. • Drilling machines can perform various operations through a few different machines like:twist drills, spade bits, and forstner bits.

30. Drilling Machine Operations Drilling, counterboring, countersinking, and reaming are common drilling operations.

31. Shaping and Planing Machines • Bothshapingand planing machines: • Use single-point tools to produce flat surfaces on metal parts and products. • Can cut on the face or side of a part. • Can machine grooves into the surface. • Are closely related to a broach.

32. Shaping and Planing Machines Shaping and planing machines move in opposite motions to produce similar effects.

33. Grinding Machines • Grinding machinesuse bonded abrasives to cut material. • The two most common are the cylindrical and surface grinders. • The pedestal grinder is also used and is a manually run machine.

34. Class Work • Answer Objectives # 1-3 • Test Your Knowledge - Page 154 - # 1 - 6 • Work on projects • Three Students to Answer Objectives • Timer • Homework - Vocabulary & Unfinished Work

35. Review • What are the categories of production tools used in technology? • Material processing • Energy processing • Information processing

36. Review What are the common characteristics of machine tools? Method of cutting, series of motions, and support of the tool and workpiece.

37. Review What are the six major types of machine tools? • Turning • Sawing • Drilling • Shaping • Planing • Grinding

38. Day 2

39. Energy-Processing Converters • Energy conversiontakes place through energy-processing converters. • There are hundreds ofenergy-processing converters. • For example: changing mechanical energy into electrical energy through an electric generator. • Three converters, the steam engine, the electric motor, and the internal combustion engine have had a big impact on technology.

40. The Early Steam Engine

41. The Watt Steam Engine • Reciprocating steam engine. • Used for industrial machines and transportation vehicles.

42. Discussion Why might steam engines not be as commonly used today?

43. Internal Combustion Engine Eachstrokecombined in a four-stroke engine completes a cycle.

44. The Electric Motor • Laws of magnetism and electromagnetism: • Like magnets repel one another, unlike poles attract. • Current flowing in wire creates electromagnetic field. • Thefield magnetand armatureare major parts of an electric motor.

45. Information-Processing Machines • Information processingincludes: • Printing. • Telecommunications. • Telephone. • Radio. • Computers.

46. The Telephone and Radio • The telephone converts sound into electrical energy. • Use has been expanded from personal communication device to a data-transmission instrument. • The radio uses radio waves that travel through the atmosphere and space. • Used to carry information and entertainment.

47. Computers

48. Using Technology Safely • In order to use technology safely: • Use the correct tools. • Remember proper operation. • Seek advice as needed. • Use only as directed. • Never use when personal ability is impaired. • Never work alone in case of an accident.

49. Personal safety: Concentrate on your work. Dress properly to protect yourself. Think before acting. Ask questions when you are unsure. Safety around others: Avoid horseplay. Do not talk with anyone operating machinery. Do not misplace tools. Safety with People

50. Safety with Materials • Handle materials properly and with care. • Check all materials for sharp burred edges and pointed ends. • Place materials in well-ventilated areas, when necessary. • Lift material properly. • Clean up and dispose of spills and materials properly.
