AMS2649D
This specification establishes the requirements for etch inspection of bare high strength low alloy steel parts having tensile strength of 180 ksi (1241 MPa) and higher and of carburized parts to detect overheating caused by abusive machining or grinding in the heat treated condition, and to detect localized discontinuous carburization. This process is not applicable to surface hardened steels produced by nitriding or carbonitriding. This process may remove 0.0001 to 0.0005 inch (2.5 to 12.7 micrometers) from the surface of the part.

This paper deals with setting of Inspection parameters for selected automotive transmission parts in various bench tests. This paper we are discuss about critical dimension's measured for particular type of test. It is not possible to measure all the dimensions of a component for doing a particular test. This is due to time constraints set by program delivery deadlines. From above statement it can be deduced that it is almost impossible to measure all dimensions of a component. A bench level test may consist of two major tests. They are maximum load test and gear shift durability test. The maximum load test deals with gear box durability test and torque carrying capacity of gearbox. Parameters to be measured for some of above parts will be identified. More importantly it will also identify see reasons for that parameter to be measured.

This paper features a set of advanced technologies for autonomy and intelligence in advanced inspection systems of facility operations. These technologies offer a significant contribution to set a path to establish a system and an operating environment with autonomy and intelligence for inspection, monitoring and safety via gas and ambient sensors, video mining and speech recognition commands on unmanned ground vehicles and other platforms to support operational activities in the Cryogenics Test bed and other facilities and vehicles. These advanced technologies are in current development and progress and their functions and operations require guidance and formulation in conjunction with the development team(s) toward the system architecture.

Precision hole inspection is often required for automated aircraft assembly. Direct contact measurement has been proven reliable and accurate for over 20 years in production applications. At the core of the hole measurement process tool are high precision optical encoders for measurement of diameter and countersink depth. Mechanical contact within the hole is via standard 2-point split ball tips, and diametric data is collected rapidly and continuously enabling the system to profile the inner surface at 0 and 90 degrees. Hole profile, countersink depth, and grip length data are collected in 6 seconds. Parallel to the active process, auto-calibration is performed to minimize environmental factors such as thermal expansion. Tip assemblies are selected and changed automatically. Optional features include concave countersink and panel position measurement.

3D digitalization and modeling is very popular in industrial applications such as metrology, geometric dimensioning and tolerancing (GD&T) and tridimensional object inspection. The 3D captured data can be used for the inspection of object surfaces. However, hidden defects cannot be detected with this technology. In order to get this kind of information, NDT/E (Non-Destructive Testing/Examination) approaches are used (ultrasounds, infrared imaging, etc.). These two types of information are very important in aerospace products inspection (e.g. composite materials). The two modalities (3D Vision and NDT) are still used separately. In this work, we present a new multi-modal fusion framework for combining these two data types. The fusion scheme works on 3D image data and temporal thermal images in order to obtain a hybrid model for simultaneously inspecting the 3D surface and the hidden sub-surface defects.

Aerospace panels are commonly restrained on complex inspection fixture jigs during the measurement process. Forces used to restrain the part are also monitored because of the part functional requirements. Given the difficulties in measuring these types of parts, this paper reviews the available fixtureless inspection methods with a focus on the challenges of their implementation and their aptitude to be used to estimate the part profile and the necessary restraining forces of an aerospace panel. To perform this investigation, finite element analysis is used to predict the constrained shape of four (4) simulated free state aerospace panel, with two different type of boundary condition, in five scenarios. From those analyses, the importance and limits of current finite element boundary setting method embedded in fixtureless inspection methods for nonrigid parts are highlighted.

Non Destructive Inspection (NDI) of large Out of Autoclave Cure primary monolithic and sandwich Composite structures is challenging due to high requirement for flaw detection and characterization among porosity, delamination, disbond, foreign material, crushed core, dry fiber. Large scale NDI inspection with semi-automated and automated system is presented for flaw detection/characterization and porosity assessment methodology is described with results for high porosity level assessment in monolithic and sandwich structures.

For decades optical camera systems have been used by Broetje-Automation to locate pilot holes and find product orientation on NC-controlled positioner systems. Measurement tolerance requirements were and are in the range of +/− 0.2 mm. Recent developments enhance the sensor technology function from pure hole detection to new features like Fastener Head Height Measurement and Countersink Diameter Measurement. While head height measurement has to go 3D by enhancing the planar sensors to head protrusion measurement, the Countersink measuring tolerances are much smaller than “simple” hole detection, in fact require more than a magnitude tighter tolerances. This paper will present how Broetje-Automation solved the issue of a 20 plus fold accuracy increase, the 3D capability of the one eyed camera and all accompanied by a more robust evaluation software.
