USING THE CASE METHOD TO FACILITATE LEARNING OF DESIGN FOR MANUFACTURING AND COST
Bibliographic record
Abstract
Design for Manufacturing and Assembly (DFMA) is anintegral methodology for product development that aimsto simplify the manufacturing process, increaseproductivity, and minimize costs while maintainingproduct quality. DFMA is often difficult since significantmanufacturing knowledge is required. The importance ofDFMA is underlined by the fact that a large portion ofproduct manufacturing costs (materials, processing,assembly and indirect costs) is determined by early designdecisions. Therefore, it is important for engineeringstudents to understand the limiting factors and practicesrelevant to the application of DFMA. Although DFMAconcepts can be taught through conventional lecturemethods, true understanding of this multi-faceted andhighly integrated strategy requires real-world practice.The case method provides an effective pedagogicalapproach to help students understand and fullyappreciate the complexity of engineering practice, gainexperience and develop the skills necessary to deal withthis complexity, and make connections between varioustopics in their undergraduate curriculum. In this paperwe describe the effort taken in Mechanical Engineering atthe University of Waterloo (UW) to develop andimplement case studies to address this gap.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
