A Free 23-Page Guide to Designing Manufacturable CNC Machined Parts
CNC machining design decisions such as tolerances, feature size, tool access, and material choice determine how many setups your part needs, how long it takes to machine, and what it costs. Our free guide breaks down the fundamentals of designing for CNC machining and covers advanced considerations like GD&T, so you can build manufacturability into your part from the start, whether you’re prototyping or scaling to production.

What’s Inside
- DFM Principles: Eight design for manufacturability principles, from simplicity and tool access to minimizing setup changes and prototyping early
- Design Considerations: How tolerances and fits, feature size, complexity, tooling, fixturing, and surface finishes affect your part, plus GD&T, designing for assembly, and toolpath optimization
- Materials: Common metals, plastics, composites, and ceramics, and how mechanical, thermal, and chemical properties should guide your selection
- Cost-Saving Tips: Ways to cut machining time and cost, such as designing on-axis planes and minimizing feature variations like internal corner radii and tapped holes
- Post-Processing: Deburring, polishing, anodizing, plating, heat treatment, and coatings, plus guidelines for planning them into your design
- Manufacturing Standards: An overview of ISO, ANSI, ASTM, and DIN, and why adhering to standards matters
