Computer Aided Tolerancing and Inspection (CAT&I) methods based on Reverse Engineering techniques may enhance production quality assessment with significant reduction of the time-to-market. This paper presents an original reverse engineering methodology that is being developed to achieve the complete automation of the inspection process starting from the design requirements (dimensional and geometrical tolerances) as they generally appear in the component's official drawings. After a brief presentation of the proposed methodology and its possible implementation oriented to non-planar surface recognition, an aeronautical component made by beta-forging of Ti6Al4V Titanium Alloy powders is presented as test case. The discussion of the procedure allows to point out its benefits in terms of (a) more efficient management of the inspection process and data consolidation; (b) more thorough comprehension of the real component; and (c) a better understanding of possible feedbacks to be applied in design or manufacturing. Finally some remarks about the limits of the proposed methodology are shown and possible enhancements, that have been already planned to be applied, will be described.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116635949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a fundamental step when maintenance and/or monitoring of the system or apparatus have to be carried out without stopping its standard operation condition. Traditional approaches usually work by measuring only the signals at the output of the final stage of the system or apparatus and trying to determine the eventual fault source. Unfortunately, they often fail when complex systems or apparatuses, characterized by several multiple and sequential stages, are taken into account; singling out the specific faulty component turns out to be impossible. Moreover, most of the considered approaches require to turn off or out-of-service the system or apparatus under test. To overcome the considered limitations, the authors suggest the insertion of digital radio frequency memories between each couple of successive stages. Thanks to the available computation power, it is possible to compensate the output of first block, thus making the successive one operating with its ideal input. This way, it should be possible to clearly and straightforwardly identify the defective stage of the chain.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131281619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current solutions includes up to 20 analog sensor boards, each with ADXL326 and ADXL377 MEMS type sensors (from Analog Device, with range of ±16g or ±200g), the data acquisition box USB-6259 (from National Instruments) with the 16-bit aggregated 1Ms/s data throughput, and data acquisition and processing software, implemented as an LabView application for the PC. Accuracy, calibration and other metrological issues have been investigated, including noise parameters and its spectra in the system and non-linearity of the sensors. The estimation of the displacements from the acceleration has been investigated, to characterize the non-linearity of the sensors and also for possible special additional measurement feature of the system. It has found, that For calibration of the acceleration and further inclination calculation the use of the natural gravitation of the earth could be used. Accuracy of the retrieving of the inclination data from the 3D acceleration sensors is under research, as well as stability in the time and temperature. Also, an example of the practical usage of the proposed system has been investigated. A section of the real-life composite boat has been equipped with the array of the sensor boards and mechanical pulse excitation has been applied to the construction with sensors. Characteristic frequencies have been extracted in the experiments, for further analysis of the variations and deviations of the parameters of the structures, being under test.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127654691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
