Common Assembly Design Mistakes in CNC Machining and Sheet Metal Fabrication

2025-09-11

In both CNC machining services and sheet metal fabrication projects, engineers often design parts that look perfect in CAD but fail during assembly.
The main issues are not exotic — they come from overlooking assembly clearance, fastening methods, accessibility, and clear annotations.

This article summarizes four key mistakes with real industry cases, practical improvements, and an engineering checklist for battery enclosures, sheet metal housings, brackets, and precision machined parts.
