4. Background and Basic Information4

5. What is Reverse Engineering?
Merriam-Webster
“to disassemble and examine or analyze in detail (a product or device) to discover the concepts involved in manufacture usually in order to produce something similar.”
New World Encyclopedia
“...a process that is designed to extract enough data from a product and then to be able to reproduce that product.” 5

6. What is Reverse Engineering?
Emphasizes functionality
Mimic
Improve
Modernize
Better understanding
Of products
Of competitors
Of marketplace 6

7. What is Reverse Engineering?
Altruistic
Improve documentation
Improve or adapt security
Education
Fix flaws
Patent infringement
Nefarious
Espionage (corporate or military)
Cloning 7

8. What is Reverse Engineering?
Hardware or Software
Hardware:
Create a comparable product
Make a product cheaper
Software:
Bridge between operating systems
Uncover undocumented features 8

9. What is Reverse Engineering?
It's a Process
Methodical
Physical
Literally take apart and inspect/assess
Digital
Scan or digitize 9

10. Where is Reverse Engineering?
Famous Examples
Assyrian Chariot → Egyptian Chariot 10

11. Where is Reverse Engineering?
Famous Examples
Carthaginian Galley → Roman Galley 11

12. Where is Reverse Engineering?

14. Where is Reverse Engineering?
Famous Examples 14

15. Ethics and Legality 15

16. Is Reverse Engineering Legal?
Copyrights versus Patents
Copyrights
Protect look and feel (shape, size, etc.)
Patents
Protect ideas (functionality, etc.) 16

17. Is Reverse Engineering Legal?
Laws change state-to-state, country-to-country
In US, usually legal for trade-secrets
Assumes that product is obtained legitimately
Not necessary for patents
Patents are public information
They describe functionality 17

18. Is Reverse Engineering Legal?18

19. Is Reverse Engineering Ethical?
What do you think?
Merriam-Webster
Conforming to accepted standards of conduct
Brainstorm...Yes?, No?, Maybe? 19

20. Approaches and Best Practices20

21. How to Approach Reverse Engineering
'Clean Room' Design 21

22. How to Approach Reverse Engineering
'Clean Room' Design
Helps to avoid copyright infringement
Especially in software
Methodical
Separation of Roles
Human Interpretation and Variation 22

23. How to Approach Reverse Engineering
Computer-Aided Reverse Engineering (CARE)
Start with physical object
Measure/scan the object
May require cleaning or minor processing
Create computer model of object
Reverse of CAD
Computer → Real-world 23

24. How to Approach Reverse Engineering
Computer-Aided Reverse Engineering (CARE)
Quickly evaluate tolerances
Electronic dissemination of information
Global trade
NASA
Archival aid 24

25. How to Approach Reverse Engineering
Contact Methods (high accuracy, slow)
Sensing
Coordinate measurement machines (CMM)
Computer numerical control (CNC)
Non-Contact Methods (low accuracy, fast)
Cross-Sections: Light, sound or magnetic fields
Triangulation
Destructive Methods
Cross-Sections: CNC 25

26. How to Approach Reverse Engineering
Small-group Exercise
Teams of 4 – 6
Split into 'Team A' (2 – 3 people)
Split into 'Team B' (2 – 3 people)
Assigned 2 products
10 minutes to inspect and describe
20 minutes to interpret and reproduce 26

27. How to Approach Reverse Engineering
Debrief
What have we learned?
Something new?
Something different?
Lunch 27

28. Design, Basis, Analysis Tool DBAT28

29. Design, Basis, Analysis Tool
Walk through as a group
Back to AM Teams
Come up with 2nd design from 'Chinese Wall'
Input both into DBAT
Print report to PDF 29

30. Reverse Engineering Challenge30

31. Reverse Engineering Challenge
Teams of 3 – 4
Use DBAT
Use any CAD software desired/accessible
TinkerCAD, 123D, AutoCAD, Solidworks
