What quality control measures are used in CNC metal fabrication?

Common QC steps include:

In-Process Inspection: Using calipers, micrometers, or coordinate measuring machines (CMMs) to check dimensions mid-production.
Tool Wear Monitoring: CNC machines often have sensors to detect dull tools (which can compromise precision) and trigger replacements.
Final Testing: Verifying parts against CAD models, conducting stress tests (for structural parts), and checking surface finishes.
Documentation: Recording machine settings, inspection results, and material specs for traceability.
