  1. Developing an Integrated Curriculum in Metrology for a Mechanical Engineering Technology Program Joseph P. Fuehne Purdue University Mechanical Engineering Technology Columbus, Indiana jfuehne@purdue.edu

  2. Learning Outcomes • Who is PCOT in Columbus? • Details including objectives of 3 new metrology-related classes • Specific lab activities • Integration into the MET curriculum

  3. Purdue University College of Technology • Statewide system • 10 locations throughout Indiana • Direct administrative link to West Lafayette campus • Not a “regional” campus • Work together with host campus to deliver program • Host campus provides instruction for general education classes

  4. Purdue COT in Columbus • Four degree programs • MET – Mechanical Engineering Technology • OLS – Organizational Leadership & Supervision • IT – Industrial Technology • CNIT – Computer & Information Technology • Commuter Campus • Low cost alternative to “main” campus • Still awarding Purdue diplomas

  5. Mechanical engineering technology • BSMET at locations is equivalent to BSMET at the main campus • Not true at regional campus although very similar • Hands-on program • Applied Engineering • Better preparation for manufacturing-related careers • No real metrology effort on the main campus • This effort in Columbus leads COT’s metrology curriculum

  6. Metrology Rationale • Critical tool in manufacturing • Underappreciated in higher education • Most engineering or engineering technology programs ignore metrology and closely-related GD&T • Only a handful of higher education institutions really address metrology in curricula

  7. Metrology Lab Collaboration • A community effort • Cummins, Inc • Community Education Coalition • Environmentally-controlled lab • Donated equipment • Starrett CMM • Optical measurement systems • Mass and length standards • Mass balances • Force measurement system • Super micrometer • Hand tools

  8. Engineering Technology vs Engineering • Metrology is a better fit in ET programs • Practical, hands-on program focused on design and production processes – manufacturing! • ET is ideal for integrating measurement devices, techniques, analysis and plan development

  9. Integrated curricula vs Skill Attainment • Integrate metrology as a tool to improve design and production process • Curriculum committees • Not necessarily interested in “Introduction to CMM” class • At least, not at upper division level • Easier to gain approval for a class that addresses overall big picture of design and production processes rather than a “skill attainment” class

  10. Inspection and Validation of Product Design • Fall 2012 class • Senior-level course (MET 490) • Satisfies an elective requirement in the POS • Addresses the efficiency and effectiveness of the manufacturing process • Class completes study of GD&T started in an earlier course • Focuses on design intent and then utilizes metrology tools for validation

  11. Laboratory Projects • Micrometer calibration • Gage R&R study using washers • Flatness evaluation • Identification and measurement of threads • Determine coefficient of thermal expansion • Perform measurements to compute density of washers and determine material • Operating a CMM to determine roundness • Operating a CMM to determine angles of holes

  12. Measurement artifacts provided by Cummins, Inc

  13. Measurement Systems Analysis • Spring 2013 class • Senior-level elective (490) • Non-laboratory activities • Develop a gage R&R spreadsheet in Excel (AIAG Measurement Systems Analysis book • Learn to describe, report and use uncertainties in measurements • An Introduction to Error Analysis by John R. Taylor • Propagation of uncertainties • Statistical analysis of random uncertainties

  14. Lab Activities • CMM programming • Reverse Engineering projects

  15. Dimensional Metrology • Fall 2013 Course • Handbook of Dimensional Metrology by Curtis and Farago • Introduction to metrology • Introduction to error analysis and uncertainty • Laboratory activities • Calibration of a micrometer • Wringing gage blocks • Measuring with optical and pneumatic tools • Employing sine bars and plates to measure angles • Measuring screw threads and gears

  16. Summary and conclusions • Integrating metrology concepts and skills (tools) into an MET curriculum • Not necessarily “skill attainment” courses • Fit metrology into larger vision of product design, inspection, and validation. • Potential for developing modules of courses into short courses or training courses
