MFG 231

Course Description

Explores the utilization of advanced measuring instruments and tools, both hand-controlled and computer numerically controlled with a focus on tight tolerances and difficult geometry. Teaches strategies and methodologies for inspecting larger quantities of parts and the processes needed to do so. References GD&T symbols necessary for more complex inspection processes and production. Prerequisite: MFG 231. Audit available.

Course Outcomes

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

  1. Program and operate measuring-specific CNC machine tools for measuring of newly manufactured parts and assemblies, mechanical repair items, and in-service parts and assemblies.
  2. Program and utilize measuring tools within part producing (production) CNC machine tools.
  3. Utilize g-code functions and prompts within in-process production of parts to ensure correct tolerance adherence.
  4. Complete advanced inspection reports for mechanical repair service items, newly manufactured components, and assemblies.
  5. Identify and apply advanced 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: Utilize strategies for measurement that are highly repeatable across larger quantities of parts.

  • Create gauges to identify pass/fail criteria for form and orientation GD&T as defined by blueprint specification

  • Define and outline secondary validity or calibration process using manual inspection strategies.

  • Identify and employ recording structures for ratio recording and percentage based data collection.

Outcome #2: Understand programming and operation of measuring-specific CNC machine tools for measurement of newly manufactured and in-service parts and assemblies.

  • Manually define datum capture using CNC Coordinate Measuring Machine (CMM) for single planar datums using expanded 3-2-1 recording.

  • Define ordinate location of planar origin from specification or in accordance with blueprint

  • Develop working program with secondary validation of results

Outcome #3: Program and utilize measuring tools within part producing (production) CNC machine tools.

  • Create CNC program stop point to allow for use of locational measuring device for geometry measurements, concentricity, and true position

  • Generate CNC program that employs use of Work Inspection Probing System (WIPS) to confirm Work Coordinate System Location

Outcome #4: Utilize g-code functions and prompts within in-process production of parts to ensure correct tolerance adherence.

  • Utilize CNC Option Stop to employ WIPS for in-process geometry inspection.

  • Program CNC to employ Cutter Diameter Compensation to maintain appropriate specification according to blueprint

  • Employ WIPS protocols for in process data capture.

Outcome #5: Complete advanced inspection reports for newly manufactured parts and assemblies.

  • Define and validate process for measuring locational datums utilizing manual measuring devices.

  • Create CNC program for CMM measurement of multi planar component geometry, translate results into record according to appropriate standards.

  • Identify and define comparison analysis points of multi part assemblies.

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

  • Understand GD&T for form to include modifier symbols

  • Expand GD&T for orientation to include modifier and reference symbols.

  • Utilize GD&T for location feature control, datum origin, and target modification symbols.
