Course Description

Explores the measurement of in-process production parts and assemblies utilizing a mix of manual devices, machine-based tools and computer numerically controlled machine processes. Designs more accurate and in-depth processes of measurement utilizing both manual and digital measuring devices for increased accuracy. References GDT symbols necessary for intermediate inspection processes and production. Prerequisites: MFG 230. Audit available.

Course Outcomes

Upon successful completion of this course, students will be able to:

  1. Identify strategies and methods of measurement and quality for in-production parts before completion.
  2. Reference appropriate datums and blueprints symbols from the GD&T environment and utilize them to pass / fail part inspection.
  3. Determine the appropriate use case for machine tool and hand tool measuring as driven by the blueprint.
  4. Complete intermediate inspection reports for mechanical repair service items, newly manufactured components, and assemblies.
  5. Create inspection processes throughout appropriate stages of production utilizing hand and CNC tools.
  6. Identify and apply intermediate GD&T symbols.

Suggested Outcome Assessment Strategies

The determination of assessment strategies is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: writings (journals, self-reflections, pre writing exercises, essays), quizzes, tests, midterm and final exams, group projects, presentations (in person, videos, etc), self-assessments, experimentations, lab reports, peer critiques, responses (to texts, podcasts, videos, films, etc), student generated questions, Escape Room, interviews, and/or portfolios.

Department suggested strategies: 
  • Lecture, in-lab coaching and direct instruction
  • Full class demonstration
  • Written exams
  • Student proficiency through demonstration of learned strategies and skills in industry standard environments
  • Job readiness based on performance
  • In class lab experiments and testing using the scientific process with written result reporting

Course Activities and Design

The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.

Course Content

Outcome #1: Identify strategies and methods of measurement and quality for in-production parts before completion.

  • Identify inspection ratio in accordance with applicable standard

  • Identify and select measuring equipment according to geometric properties of components.

  • Use applicable GD&T standards to create an in-process inspection flow chart.

Outcome #2: Reference appropriate datums and blueprints symbols from the GD&T environment and utilize them to pass / fail part inspection.

  • Identify planar coordinate datums applied to in-process measuring and GD&T.

  • Identify basic geometric relationships of datums such as runout, concentricity, and parallelism

Outcome #3: Understand the appropriate use case for machine tool and manual tool measuring as driven by the blueprint.

  • Relate and utilize tolerance specifications to select appropriate measuring devices.

  • Select measurement strategies that align with component geometry, and acceptable GD&T or Class Fit schedule.

  • Employ secondary measurement strategy to confirm or validate results

Outcome #4: Complete intermediate inspection reports for newly manufactured parts and assemblies

  • Align measuring process flow charts with appropriate specifications according to blueprints

  • Define inspection process for ratio or whole data capture

  • Define tolerance stacking of multi part assemblies according to appropriate standard

Outcome #5: Create inspection processes throughout appropriate stages of production utilizing hand and CNC tools.

  • Utilize manual and digital measuring devices to carry out measuring strategies in accordance to tolerance specification.

  • Align in-process inspection and root cause analysis in data collection

  • Define solutions using inspection data

Outcome #6: Understand and Identify intermediate GD&T symbols.

  • Identify GD&T symbols for form, orientation, and location

  • Understand and utilize 3-2-1 methodology to select appropriate measurement devices

  • Utilize planar relationships for validation of compliance and measurement categorization
