1. Spring 2001 ISAT 430 Dr. Ken Lewis 1 Things to Know Review ISAT 430

2. Spring 2001 ISAT 430 Dr. Ken Lewis 2 Process-Property-Product-Performance Continuum Understand how Product performance Composition and structure Synthesis and processing Assumed behavior interact

3. Spring 2001 ISAT 430 Dr. Ken Lewis 3 Manufacturing Processes Know what the processes are doing Changing the state, geometry, physical properties, appearance,…. Changing the value of the material Know that (in principle) manufacturing adds value to the material.

4. Spring 2001 ISAT 430 Dr. Ken Lewis 4 History For millennia, stuff was made One of a kind Labor intensive A person was a jack of all trades Material discovery drove manufacturing processes Wood Fibers Clay metals

5. Spring 2001 ISAT 430 Dr. Ken Lewis 5 History Industrial revolution (1760 – 1845) The steam engine Machine tools Textile machinery The factory system Other forces Eli Whitney – interchangeable parts Henry Ford – the assembly line

6. Spring 2001 ISAT 430 Dr. Ken Lewis 6 Conversion Extraction Bring it from the earth Cast or form Bring it to use

7. Spring 2001 ISAT 430 Dr. Ken Lewis 7 Manufacturing Processes Conversion Raw or natural to a more useful finished form Processing Transform a material Assemble Many parts into one.

8. Spring 2001 ISAT 430 Dr. Ken Lewis 8 Process Selection If you can find or discover a process, there are bases for the choice Technical Do not violate the laws of physics in our area of the known Universe Economical Can I do it and make a profit? Compatibility Know obvious incompatibilities Forging a plastic Blow mold aluminum

9. Spring 2001 ISAT 430 Dr. Ken Lewis 9 Process Selection Economics Numbers –vs- cost Inspection Reduction in versatility Capital investment Conversion costs Environmental Waste production, release, and conversion costs Miscellaneous Material availability Time lines And all others,… supply, labor, deadlines…

10. Spring 2001 ISAT 430 Dr. Ken Lewis 10 The Effect of Numbers On Process Selection understand
