Dimensional Control Engineering for
: The Aerospace Industry
Absolute Precision, Assembly Certification, and Regulatory Compliance
In aerospace manufacturing, perfection is not a competitive advantage—it is a prerequisite (AS9100 Standard). Aircraft assembly requires the joining of large structures where deviations of just a few millimeters can cause material stress, aerodynamic drag, or the rejection of valuable components.
The major production bottleneck is usually found in the setup of large tooling and in the final integration (mating).
The Tecnimex Group is your metrological validator. With laser trackers and advanced 3D scanning, we eliminate uncertainty during assembly. We ensure that molds, fixtures, and tools are strictly within the specified tolerances (GD&T) from the very first setup.
Critical Solutions and Applications
Assembly and Tooling Control
Calibration of Jigs and Fixtures:
Inspection and certification of assembly, machining, and welding equipment. Ensures precise clamping and repeatability on the production line.
Inspection of Composite Molds:
3D verification of the profile of molds for carbon fiber lamination, ensuring the part's complete aerodynamic accuracy.
Integration and Alignment
Structural Alignment (Mating):
Precision control in the assembly of large modules (wing-fuselage, stabilizers, landing gear). Eliminates residual stresses caused by forced fits.
As-Built Scanning:
High-resolution 3D scanning of aerodynamic surfaces (airfoils) and complex parts for direct comparison with the original CAD model.
Maintenance and Modernization
MRO (Maintenance, Repair, and Overhaul) Support:
3D measurement of aircraft on the ground to identify structural deformations caused by fatigue or hard landings, and assessment of wear on critical components.
Reverse Engineering:
Scanning and creation of CAD models of legacy components (without documentation), enabling the modernization of older fleets.
AS9100 Standard and Airworthiness
We comply with the requirements of the AS9100 standard and Geometric and Dimensional Tolerancing (GD&T) controls. Using laser trackers, photogrammetry, and laser scanners, we deliver definitive solutions for risk mitigation, ensuring the complete integrity and airworthiness of aerostructures.
The Tecnimex Advantage: Precision in High-Volume Production
Large-volume metrology requires equipment that maintains uncertainty in the micrometer range, even over distances of tens of meters. We combine cutting-edge technology with in-depth practical knowledge:
Clear Diagnoses
We don't just provide numbers. Our reports guide engineers toward fast and safe calibrations.
Project Acceleration
Traceable data reduces rework costs, ensures the plant remains in continuous compliance, and accelerates time to market.
