Imagine you’re designing a custom part for your project—maybe a bracket for a car’s electrical system or a housing for a small sensor. You’ve narrowed down the material to either aluminum (metal) or ABS (plastic), but now you’re stuck: Do you use CNC turning or milling? And will the process work the same for both materials?

If you’ve ever had a CNC machining project go off the rails—parts that don’t fit, costs that spiral, or lead times that stretch too long—you know how frustrating it can be.
