Design for Manufacturing DFM Review Checklist

This document is a Design for Manufacturing (DFM) review checklist created by Boothroyd Dewhurst, Inc. It outlines various process-specific prompts aimed at identifying manufacturability issues prior to product release. The checklist emphasizes the importance of considering factors such as expected annual volume, target processes, material grades, and supplier capabilities. It provides guidelines for assessing design fundamentals, standardization, and process selection based on volume and cost. The document details specific considerations for various manufacturing processes, including CNC machining, injection molding, sheet metal fabrication, die casting, hot forging, investment casting, extrusion, and PCB fabrication. Each section lists critical questions and criteria to ensure manufacturability and cost-effectiveness, encouraging users to flag items for further engineering or supplier review. The checklist serves as a tool for enhancing design efficiency and reducing potential manufacturing challenges.
