Aluminum CNC Machining Surface Finishes
Cost-saving Design Tips
1.Design for manufacturing
The first tip to save cost when machining an aluminum alloy part is to follow design-for-manufacturing principles to limit difficult-to-machine features, such as setup numbers, inspection dimensions, tight tolerances, and deep pockets with small radii.
2.Choose the right alloy
Using the most innovative and pricey alloy might not be needed if the part is just a prototype. 6061 T6 aluminum is a good choice.
