A 3-D CAD modeling case study: Using the prototype to develop a design for production

摘要

In the previous edition of this column ("A 3-D CAD modeling case study: What comes first-design for manufacturability or supply chain issues," Precision Matters, The FABRICATOR?, July 2018, p. 38), the scope of design for manufacturability (DFM) needed to include planning for regulatory compliance. Every purchase, even at the early prototype stage, created inventory that had to be isolated as "noncompliant" from inventory that satisfied regulatory constraints. Similarly, choices made in subcontracting made an impact on inventory certification.
