Note: Proper planning reduces the risk of missed errors and ensures that the inspection process covers all essential aspects of lami tube manufacturing.
Material and Dimension Checks
Once preparation is complete, the team selects a representative pre-production sample from the initial production run. The inspection focuses on verifying that the sample meets all design and buyer requirements. Inspectors use calibrated tools to measure dimensions and check for defects. Comparing physical characteristics to engineering drawings and specifications remains a critical step.
Common measurement tools include:
Measurement Tool
Application
Notes
Outside Micrometer
Best for measuring round features with small tolerances
Provides high accuracy but may not access hard-to-reach areas.
Vernier Caliper
Suitable for general measurements, but less accurate than micrometers
Can show out-of-tolerance results if the tolerance is small.
Radius Gages
Used for measuring radii, especially in cases of high variability
Often a subjective go/no go gauge; can be appropriate for difficult measurements.
Profile Requirement
Alternative to radius dimensions, focusing on surface specifications
Reduces measurement uncertainty by avoiding direct radius measurements.
Inspectors conduct dimensional and visual inspections, measuring each feature against the specified requirements. They also perform functional and performance testing to verify that the part meets performance standards. Measurement uncertainty can affect reliability, so teams may measure the same dimension multiple times to ensure accuracy. High variability often occurs when measuring circular features, especially radii, so inspectors must use the most suitable tools and techniques.
Tip: Prioritizing critical dimensions and using automated measurement systems can help reduce human error and improve product quality.
Documentation
Accurate documentation ensures traceability and compliance throughout the first article inspection. Inspectors record every step and result in a standardized report. The documentation process includes three main forms:
Form Number
