1. Faculty Use and Sources For Standards Examples & Standards

2. Uses in Capstones Projects (Conceptual, virtual or real) using realistic design constraints. CAD systems are theoretical unless ‘real’ values are used Research into standards (examples of what particular standards control some part aspect, details in standards beyond handbooks, specific basis for municipal / state / national codes, etc.)

3. US Domestic Standards Most by gift or discount from SDO, broker Mechanical Engineering –Materials, fasteners, metrology, fits dimensioning & tolerances, tools, 3D CAD Nuclear Engineering –Materials, design, plant construction, operational parameter Electrical/Computer Engineering –Materials, components, circuit protocols, networking, communications

4. International Standards Most free from ANSI or discount from SDO, broker IEC (International Electrotechnical Commission) –Devices, techniques for electrical and controls systems (many co-branded) ISO (International Organization for Standardization) –Almost everything from banking to mining to fasteners to medical devices ITU (International Telecommunications Union) –Telephony, television, networks (think 4G)

5. ABET — Criterion 5 - General Curriculum (2011-2012) Students must be prepared for engineering practice through a curriculum culminating in a major design experience based on the knowledge and skills acquired in earlier course work and incorporating appropriate engineering standards and multiple realistic constraints.

6. Case Study: Simple Mechanism to Illustrate the Ubiquitous Nature of Standards Even a simple device can require complex real-world decision- making based on the use of standards

7. Project Presented as a 3-Part Capstone via ECOs Key Concepts: ECO, unit conversion using hard conversion, a practice common in metric countries. Add metric parts as teams both discrete and systems thinking required.

8. Task: In three phases, design a Customary Inch arbor press in SI preferred numbers according to ECOs How many standards? Hint: Over 22! 6 fasteners, 4 threaded holes, 2 clearance holes, 3 fits, 1 finish, 2 plating, 2 counterbores, knurling, preferred numbers, SI sheet metal, ring groove, gears, others. (ASTM, ASME, ISO)

9. Task: Redesign a Customary Inch arbor press in SI preferred numbers ECOs: Convert inch dimensions and parts to SI preferred numbers. Retain approximate trade size, calculate mass properties, add GD&T. ECO1 & 3 are individual phases, ECO2 is accomplished as teams.

10. Unit Conversion Drill sizes to preferred numbers

11. Issues with fasteners CAD models vs. real sizes Thread length vs. tap drill hole depth Costs vs. functionality Clearance holes Other clearances

12. Issues with virtually all headed fasteners Ref. ASME B18.3.3-1986, Hex Socket Head Shoulder Screws

13. Task: Redesign a Customary Inch arbor press in SI preferred numbers ECO 2: As a team resolve issues when using assembly parts from each team member. Substitute standard parts for certain non-standard parts, substitute fasteners. build mating features using standard metric fits. Retain approximate trade size, add additional intelligent properties.
