Application Case Study: Supercharger Vane Clearance Inspection

Component Overview

Type: Supercharger Vane
Material: Aluminum
Metrology System: MVi5 3D Metrology Center
Metrology Service: Form Measurement and Clearance Validation

Clearance Inspection Process

The aluminum supercharger vane was scanned using the MVi5 3D Metrology Center to capture a full digital representation of the part. Cross-sectional profiles were extracted from the scan to measure critical dimensions affecting vane clearance and performance.

Measurements included slot width, sidewall angle, and gap uniformity between mating components. The non-contact scanning ensured that no mechanical stress or deformation was introduced during the inspection process, preserving component integrity.
