1. Chp 7 Production Tools and Their Safe Use
Spring 05
Foundations of Engineering and Technology

2. Objectives: Categories of production tools used in technology
Characteristics of Machine tools
Identify major types of machine tools
Describe the major types of energy processing tools and machines
Describe the major types of information processing tools and machines
List guidelines for using tools and machines properly and safely

3. Materials Processing Tools and Machines-pg 127
Machine Tools-machines used to make other machines
Characteristics of Machine Tools:
A method of cutting materials-cutting tool
A series of motions between tool and material
Support of tool and workpiece

4. Cutting Tools-pg 128 Two Basic Types-
1. Single Point-knives, chisels and planes
2. Multipoint-saw blade

5. Motion-pg 129
2 Main Types
Cutting-action that causes material to be removed from the work
Feed-brings new material to the cutting tool
Kerf-the slot where the material has been cut away
All feed can be categorized as: pg 135
Rotating-
Reciprocating
Linear

6. Support-pg 130
Chucks
Arbors

7. Types of Machine Tools-pg 131
6 Categories:
Turning-use a process in which a workpiece is held and rotated on an axis-lathe
Sawing-use teeth to cut material-crosscutting, ripping, resawing, grooving, chamfering.
Three Types of Saws:
Circular-crosscutting, ripping and combination cutting
Band-continuous strip with teeth on one edge
Scroll-up and down motion-teeth on one edge
Drilling-produce or enlarge holes via a rotating cutter
Types of operations-
Drilling-producing straight, cylindrical holes
Counter boring-producing two holes around the same center point
Countersinking-producing a beveled outer portion of a hole
Reaming-enlarging the diameter of a hole
Shaping-metal working machine tools product flat surface
Planing
Grinding-remove very small pieces with random cutting surface

11. Energy-Processing Converters

12. Energy-Processing Converters
Law of Conservation of Energy-energy cannot be created or destroyed…it can only change form
Conversions:
Mechanical to electrical
Electrical to mechanical
Radiant to thermal
Heat to mechanical

13. Steam Engine Early 1700’s Major impact from Industrial Revolution
Allowed control of:
Intensity, duration, and location of power
Major impact on civilization as we knew it

14. Internal Combustion Engine
Developed late 1800’s
Powers vehicles
Use gasoline and/or diesel
Two Stroke or Four Stroke
Stroke-movement of a piston from one end of a cylinder to another
Cycle-complete set of motions needed to produce a surge of power
Intake, Compression, Power and Exhaust

15. Electric Motor Most universally used source of power
Based on the laws of magnetism:
Like poles repel, unlike poles attract
Current flowing in a wire creates an electromagnetic field around the conductor

16. Information Processing Machines

17. Communication Methods
Basic to all modern communication systems are printing, telecommunications and computer

18. Printing Moveable type 1400’s First book he printed was the Bible
Johann Gutenberg

19. Telecommunications Telephone-Alexander Graham Bell Radio-Marconi
Hardwired-each telephone has a separate wire to transmit the signal
Radio-Marconi
1901
Used for ships to send danger signals

20. Computers
5 parts:
Input-keyboard, storage devices, modems, mice, other computers+
Processing-
CPU-central processing unit
RAM-Random Access Memory-short term temporary memory-NOT the hard-drive
Output
Memory
Program

21. Production Tools
What makes the
Manufactured Goods

22. Flow Chart Symbols
Operation - Object is changed in its chemical or physical makeup. It is assembled or disassembled.
Transportation – Object is moved from one place to another
Inspection – Quality of the object is inspected
Delay – Object is held awaiting the next operation
Storage – Object is placed in a protected location
