Sophisticated, Non-contact, Measuring Solutions

The commercial aviation and aerospace industry is on the leading edge of fabrication and assembly technology, constantly striving to create new products and improve existing ones. Many improvements, through recent research and development in metrology, are now available to the aerospace products manufacturing industry.

Aerospace applications require uncompromising attention to detail and performance in extreme operating conditions. Aircraft have parts and assemblies in operation on-board for vital applications that demand 100% inspection. Hydraulics, turbines, gear boxes and landing systems are a few of the applications where you’ll find parts and assemblies requiring high precision geometric dimensioning and tolerancing.

From defense to commercial and general aviation, Autonetics sophisticated measuring applications and software provides stand alone and in-production inspection for a wide variety of critical components.

Inspection tolerances for the aerospace industry are extremely high; however, the ability to adhere to these tolerances while quickly and accurately measuring a part in-process can be a challenge. As large-scale parts are brought together, such as engines and fixtures, operators must ensure that each part is accurately measured and correctly aligned. Inaccurate measurements during inspections can result in future rework, costing manufacturers both time and money. Autonetics purpose designed solutions, are able to provide quick measurements with consistent, accurate results directly on the shop floor.

For example turbine blades are inspected to ensure premium economy and long life in harsh turbine operating conditions. Most blades are verified through touch sensor based CMM inspection. However this type of inspection is time consuming and requires knowledgeable inspection personnel. Manufacturers are increasingly turning to optical sensors to verify the shape of the aerodynamic blade surface and the dimensions of milled planes, flanges, drilled holes and alignment notches.

Compared to traditional tactile inspection laser arrays capture much more point data in a shorter time frame, and embed measurement and analysis in an automated digital inspection process. At the same time, non-contact measurement requires little or no blade pre-alignment, and eliminates probe compensation when scanning freeform blade surfaces. By capturing thousands of inspection points per second, Autonetics software is able to apply far more accurate profiling to determine the positions of features and verify the correct dimensional geometry. Autonetics proprietary sensor arrays and advanced software are the cornerstones of a much faster and operator-independent inspection process.
