Course Description

Introduces concepts of precision measurement, GDT and dimensional tolerance using hand tools and industry standard blueprints. Explores techniques used for accurate measurement after production of parts and assemblies to specification, and for inspection of in-service parts and assemblies for appropriate wear tolerance. References GDT symbols necessary for basic inspection processes and production.

Course Outcomes

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

  1. Identify and use different types of manual precision measuring tools, identify and apply correct values for fasteners by type and grade.
  2. Complete basic inspection reports for mechanical repair service items, newly manufactured components, and assemblies.
  3. Create quality control processes for approval/rejection of created and received parts.
  4. Identify tolerance, total tolerance, and their use in field service and metrology environments in accordance with necessary and applicable standards.
  5. Create processes for hand tool measuring of in-service parts and assemblies to blueprint specifications.
  6. Identify and apply basic GDT symbols in accordance with necessary and applicable standards.

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 and use different types of precision measure hand tools, identify and apply correct values for fasteners by grade.

  • Read manual measuring tools and Vernier scales utilizing the appropriate math skills necessary for accurate interpretation of measurement results Calibrate various types of hand tools utilizing gauge blocks, and other calibration tooling for precision measuring tools.

  • Demonstrate proficiency and repeatability in measuring tooling usage

  • Identify fastener type grade and proper torque values

Outcome #2: Complete basic inspection reports for mechanical repair service items, newly manufactured components, and assemblies.

  • Correctly interpret and transcribe data as required per inspection process

  • Understand symbols necessary for data input in to basic inspection sheets

  • Reference datums using appropriate tooling to verify accuracy and tolerance

Outcome #3: Create quality control processes for approval/rejection of created and received parts

  • Interpret critical datums, class fits for ASME specification

  • Critically analyze datums to determine best practice of accurate measurement for part

  • Consider geometrical differences and how they may affect measuring strategy

Outcome #4: Identify tolerance, total tolerance, and their use in field service and metrology environments, introducing physics for thermal activity.

  • Interpret tolerance for a set of blueprints, as drawn

  • Determine total tolerance for a group of parts across an assembly, identify clearance, interference and tolerance class fit

  • Analyze the effect of the total tolerance stack across prints in an assembly

  • Analyze the effect of thermodynamics as applied to metal types

Outcome #5: Create a manual measuring process for field service parts and assemblies to blueprint specifications.

  • Based on parts without an existing blueprint, determine necessary tolerances for approval/rejection for service.

  • Identify critical datums and reference datums for measuring using the 3-2-1 rule

  • Create a list of necessary tooling for successful measurement for approval/rejection of a part

  • Write an inspection sheet to capture the appropriate data.

Outcome #6: Understand and identify basic GD&T symbols.

  • Read and understand GD&T symbols as appropriate for basic blueprints

  • Interpret GD&T symbols usage within the context of a blueprint’s geometry

  • Interpret and relate Class Fits in accordance with necessary and applicable standards.
