Manual Quality Inspection |
|
A ship centrifugal pump manufacturer was noticing quality issues in prototype pumps they were designing. All sub-assemblies appeared to be within tolerance, but their alignment was off when assembled.
They decided to hire a Perceptron value added reseller to perform quality checks on a small sample of prototype pumps and investigate what was causing the problem. As a result, the value added reseller concluded the parts were misaligned, overlapping in areas and some walls had non-uniform thickness. They directed the manufacturer where to make adjustments and by how much.
Quality inspection process:
- All accessible parts of the centrifugal pump were scanned and aligned
- NURB surfaces were created from the scan data
- The operator performed curvature test to see difference between design and prototype
- Section cuts were taken to see the difference between design and prototype
- Measurements were taken to give manufacturer inputs for casting and product design changes
