CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority under 35 U.S.C. 119(e) to U.S. application No. 62/055,026 filed Sep. 25, 2014, entitled “Inspection Tool for Manufactured Components”, the entire contents of which are hereby incorporated by reference. 
     
    
     TECHNICAL FIELD 
       [0002]    The present invention relates to the field of inspecting manufactured components and more particularly, to validating measurements of manufactured components compared to nominal values. 
       BACKGROUND OF THE ART 
       [0003]    In certain fields, such as the aerospace industry, components that deviate from nominal values even minimally are found to be unacceptable. The requirements for fabrication are very stringent and inspection is critical to ensure high quality products. However, when different components are fabricated by different suppliers, it can be difficult to obtain a same quality of inspection across all suppliers. It can also be difficult to receive inspection reports that are uniform and provide the same level of detail. 
         [0004]    Therefore, there is a need to overcome some of the challenges associated with the inspection of components.

       DETAILED DESCRIPTION 
       [0047]      FIG. 1  is a flowchart of an exemplary computer-implemented method as performed by an inspection tool. In a first step  102 , measurement data for the manufactured component is received.  FIG. 2  is an exemplary component  200  intended for assembly with other components to form an aircraft. The component  200  is a horizontal stabilizer (H-stab) of the rear of an aircraft. The H-stab will form part of the tail of the aircraft when assembled with a vertical stabilizer and a rudder. Some of the locations on the component  200  from which measurements may be taken and provided as measurement data are illustrated in  FIG. 2 . In this example, eleven points are measured on the component and are identified as HS 1 R, HS 2 R, HS 3 R, HS 4 R, HZ 1 , HZ 2 , HZ 3 , HS 1 L, HS 2 L, HS 3 L, and HS 4 L. More or less than these measurement points may be obtained. Measurements may be taken manually or using one or more automated tools. Note that a component and/or assembly reference system is used to locate the measured points in space. In the case of the H-stab, an aircraft reference system is used and each point on the aircraft may be referred to with an (x, y, z) coordinate. 
         [0048]    The measurements may be provided to the inspection tool using a graphical user interface, as will be described in more detail below. Similarly, the points to be measured may also be displayed on a graphical user interface for an operator to perform the measurements and/or to control measurement tools for obtaining the measurements. 
         [0049]    Referring back to  FIG. 1 , measurement data is compared to tolerance data for at least one feature in step  104 . In some embodiments, the measurements are themselves compared to nominal values for the measured points. Alternatively, the measurements are used to calculate parameters corresponding to at least one feature of the component. For the H-stab, some examples of parameters are a sweep angle, a dihedral angle, and a differential incidence. Other parameters may also be determined for the H-stab. Different parameters will be determined as a function of the component under inspection and the desired features to be inspected. 
         [0050]    Various calculations may be performed to determine the parameters. In some embodiments, only part of the (x, y, z) coordinate for a given point is used in a calculation. For example, the left and right dihedral angles may be calculated using the following, respectively: 
         [0000]      Arctan((HS2L Z−HS4L Z)/(HS4L Y−HS2L Y))
 
         [0000]      Arctan((HS2R Z−HS4R Z)/(HS4R Y−HS2R Y))
 
         [0051]    An H-stab differential dihedral angle may then be calculated by subtracting the right dihedral angle from the left dihedral angle. The dihedral angle may also be calculated using other points on the component and/or other formulas. The calculations may be performed automatically on the basis of the measurement data as received. Alternatively, the tool may require additional input from the user to calculate the parameters, such as a prompt or an identification of the parameters to be calculated. 
         [0052]    As per step  106 , a pass/fail status is determined based on a comparison of the calculated parameters (or the measurement data) with tolerance data. Tolerance data refers to the amounts by which specified nominal values may vary without significantly affecting the functioning and/or the quality of the component. The tolerances are specified for each feature of the component to allow reasonable leeway for imperfections and inherent variability without compromising performance. A variation beyond the tolerance is said to be non-compliant. 
         [0053]    Each parameter may be assigned a set of tolerances including a minimum and a maximum deviation from the specified nominal value. For example, the sweep angle may deviate by a minimum value of −0.05° and a maximum value of +0.05°, or ±0.05°. Similarly, the dihedral angle may deviate by a minimum value of −0.15° and a maximum value of +0.15°, or ±0.15°. These values are obtained by a parameterization of a given component. They may be specified using various mathematical models and/or computer simulations in order to determine the acceptable tolerances for each feature of the component. 
         [0054]    In some embodiments, an entire assembly is parameterized feature by feature, i.e. parameterization is performed for a plurality of components assembled together. For example, an entire aircraft may be parameterized by defining the nominal values for the parameters of each component, and by defining allowable tolerances for each parameter. The interaction of one component with another component within the assembly is thus considered for an assembly parameterization. For example, the H-stab is meant to interface with the fuselage of the aircraft. An excessive deviation in the dimensions of the interfacing surface may cause a clash or an excessive gap with the fuselage. Non-compliant dimensions of the H-stab may also cause an excessive transverse load on an actuator of the aircraft. If one or more of the various angles defined by the H-stab are non-compliant, it may lead to a decreased performance of the aircraft due to excessive fuel consumption or reduced maneuverability of the aircraft. In some embodiments, a parameterization may take into account a specific model of the assembly, a manner in which the components are assembled together, industry standards for performance, safety requirements, and/or materials. These factors may be considered individually or using any combination thereof. 
         [0055]    As per step  110 , the potential impacts associated with a given parameter are displayed by the inspection tool for parameters having a fail status. In some embodiments, a risk scale may be used to further qualify the potential impact and the risk level is displayed with the potential impact. The scale may have two, three, or more levels, each level indicating a risk level of the potential impact occurring. For example, the scale may comprise three levels set to low risk, medium risk, and high risk. In another example, the scale may comprise four levels set to low risk, risk, high risk, very high risk. The risk scale may be set with the number of levels as desired. In some embodiments, each level may be associated with a range of values beyond the tolerance data. For example, if the tolerance for the sweep angle is set to ±0.05°, the risk scale may be set as follows: 
         [0000]    
       
         
               
               
             
           
               
                 TABLE 1 
               
               
                   
               
               
                 Deviation 
                 Risk Level 
               
               
                   
               
             
             
               
                 ±0.05° 
                 No Risk 
               
               
                 ±0.06° 
                 Low Risk 
               
               
                 ±0.07° 
                 Medium Risk 
               
               
                 ±0.08° 
                 High Risk 
               
               
                   
               
             
          
         
       
     
         [0056]    In some embodiments, the risk scale is used for variations within the tolerance data instead of beyond the tolerance data and the highest level is set for a deviation of the maximum/minimum amount from the nominal value. For example, the risk scale for the sweep angle may be set as follows: 
         [0000]    
       
         
               
               
             
           
               
                 TABLE 2 
               
               
                   
               
               
                 Deviation 
                 Risk Level 
               
               
                   
               
             
             
               
                 ±0.02° 
                 No Risk 
               
               
                 ±0.03° 
                 Low Risk 
               
               
                 ±0.04° 
                 Medium Risk 
               
               
                 ±0.05° 
                 High Risk 
               
               
                   
               
             
          
         
       
     
         [0057]    The increments of the risk scale may be constant or they may vary from one level to the next. For example, the difference between the first level and the second level may be 0.01° while the difference between the second level and the third level may be 0.005°. The values associated with each level of the risk scale may be set in accordance with a desired specificity for manufactured components. Increments may be of one decimal place (0.x), two decimal places (0.0x), three decimal places (0.00x), etc. The units of the increments will correspond to the units of the parameter or measurement data, such as degree, radian, steradian, meters, kilograms, square meter, cubic meter, etc. 
         [0058]      FIG. 3  is an exemplary graphical user interface  302  for inspection of the manufactured component to be assembled with other components. In some embodiments, an input area  304  is provided for receiving measurement data for the manufactured component. In this example, separate values are entered for x, y, and z coordinates. However, data may be entered in various ways. One or more fields may be displayed for data entry, such as in a table format, as illustrated, or one at a time. The points to be measured on the component may form sub-groups for which data is entered together. For example, and as is illustrated in  FIG. 3 , data entry fields  305  are displayed for points HS 1 R-HS 4 R. Data entry fields for other points to be measured may be displayed separately once the data has been entered for points HS 1 R-HS 4 R. 
         [0059]    In some embodiments, an actionable object  306  is provided. The actionable object  306  may be any graphical control element that invokes an action when activated by a user. It is selectable by a user for confirming that the measured data has been entered. In this example, a “next” button  308  is used to confirm that data for points HS 1 R-HS 14  has been entered and to move on to another set of points. A “done” button  310  is used to confirm that all measurement data for the given component has been entered. The actionable object  306  may take various forms, such as a button, a slider, an icon, a list box, a spinner, a drop-down list, a link, a tab, a scroll bar, and/or any combination thereof. More or less elements may be used for the actionable object  306 . In some embodiments, the actionable object  306  may comprise a control element to select a component, an assembly, a model of the assembly, and/or a measured point on a component. For example, the actionable object  306  may be a pull-down menu with a list of measured points and upon selection of one, a data entry field is presented to the user in the input area  304 . 
         [0060]    In some embodiments, the measurement data may be provided automatically to the inspection tool without manual entry. For example, the inspection tool may be operatively connected to a measurement tool and data may be transferred from the measurement tool to the inspection tool. Other methods of providing measurement data to the inspection tool will be readily understood by those skilled in the art. 
         [0061]      FIG. 4  is another example of a graphical user interface  402 . In this embodiment, an output area  404  is provided for displaying a result of the comparison of the measurement data with the tolerance data for at least one feature of the manufactured component. In some embodiments, the output area comprises only a pass/fail status and for each fail status, an impact resulting from assembly of the manufactured component with the other components. In some embodiments, the risk level of the impact in accordance with the risk scale is also displayed. In some embodiments, a deviation amount for a fail status is also displayed. The deviation amount may be displayed without the risk scale. Other information may also be displayed, such as the measurement data and/or calculated parameters, and the minimum/maximum tolerance values. 
         [0062]      FIG. 5  is yet another example of a graphical user interface  502 . In this embodiment, a graphical representation  504  of the measurement data is provided in the output area. In this example, the sweep angle is illustrated using a top view of the H-stab. The parameter, obtained from the measurement data, is illustrated for the left sweep angle  508   a  and the right sweep angle  508   b.  In some embodiments, the tolerances may also be illustrated, such as the left maximum sweep angle  506   a,  the left minimum sweep angle  506   b,  the right maximum sweep angle  506   c,  and the right minimum sweep angle  506   d.  The visual impact of the parameter bounded by the tolerances immediately conveys the pass status of the measurement data for the sweep angle. In the example of  FIG. 5 , the measurements are provided on an engineering drawing. Other types of images may also be used, from photographs to hand-drawings, to represent the component under inspection. The sweep angle is best illustrated from a top view of the component.  FIG. 6  illustrates a graphical representation  504  of the dihedral angle, this one overlaid on a back view of an engineering drawing. The inspection tool may thus be configured to select the appropriate part with the corresponding drawings having been parameterized with the predetermined sets of tolerance data and graphically illustrate the measurements. 
         [0063]    In  FIG. 6 , the calculated angle  606   a,    606   b,  is shown to be outside of the tolerance zone, defined by lines  604   a,    604   b,    604   c,  and  604   d.  Color-coding or other visual indicators may be used to more easily distinguish between the lines that represent measurement data and the lines that represent tolerance data. For example, the measurement data lines  508   a,    508   b  of  FIG. 5  have a small shape at their extremities while in  FIG. 6 , these lines  606   a,    606   b  are provided with a thicker profile. Other distinguishing techniques may be provided. In addition, the inspection tool may be configured to selectively display only the measurement data or only the tolerance data, as per user input. 
         [0064]    In the examples of  FIGS. 5 and 6 , the actionable object  306  is provided as a set of hyperlinks associated with the name of the parameter. These hyperlinks allow the user to select the graphical representation from any one of the features represented by the measurement data. Other means of switching between graphical representations, such as window tabs or drop-down menus, may also be used. 
         [0065]    The measurement data may refer to a dimension or an angle. Since the deviation from a nominal value may be extremely small, such as to the hundredth of a degree or a cm, the measurement data may be processed to properly display the information on a much larger scale, i.e. that of the component on the engineering drawing or another image of the component. The inspection tool is may thus be adapted to extract the values as measured, amplify them accordingly, recalculate the points of interest and trace the lines on the engineering drawings (or another image) to provide the graphical representation  504 . 
         [0066]    The output area  404  of the graphical user interface  402 ,  502 ,  602  may be configured in various ways to display the result of the comparison of the measurement data to the tolerance data. The pass/fail status and resulting impact of one or more features may be displayed. Any combination of actual measurements, calculated parameters, tolerance data, risk level, deviation from tolerance data, and graphical representations may be provided. In some embodiments, the output area  404  is customizable to provide the information as desired by a particular user. Note that while the input area is illustrated in  FIG. 3  as its own graphical user interface  302  window, a single graphical user interface may provide both the input area and the output area in a single window for viewing on a single screen. 
         [0067]      FIG. 7  illustrates an exemplary embodiment for the inspection tool  700 . The inspection tool  700  may reside on one or more server(s)  701 . For example, a series of servers corresponding to a web server, an application server, and a database server may be used. These servers are all represented by server  701  in  FIG. 7 . The inspection tool  700  may comprise, amongst other things, a processor  704  in data communication with a memory  702  and having a plurality of applications  706   a,  . . . ,  706   n  running thereon. The processor  704  may access the memory  702  to retrieve data. The processor  704  may be any device that can perform operations on data. Examples are a central processing unit (CPU), a microprocessor, and a front-end processor. The applications  706   a,  . . . ,  706   n  are coupled to the processor  704  and configured to perform various tasks. It should be understood that while the applications  706   a,  . . . ,  706   n  presented herein are illustrated and described as separate entities, they may be combined or separated in a variety of ways. It should be understood that an operating system (not shown) may be used as an intermediary between the processor  704  and the applications  706   a,  . . . ,  706   n.    
         [0068]    The memory  702  accessible by the processor  704  may receive and store data, such as measurement data, tolerances, parameters, pass/fail statuses, potential impacts, risk scales, images of the components, graphical representations of parameters, graphical representations of tolerances, scaling factors, parameterized models of components, etc. The memory  702  may be a main memory, such as a high speed Random Access Memory (RAM), or an auxiliary storage unit, such as a hard disk or flash memory. The memory  702  may be any other type of memory, such as a Read-Only Memory (ROM), Erasable Programmable Read-Only Memory (EPROM), or optical storage media such as a videodisc and a compact disc. 
         [0069]    In the embodiment illustrated, the inspection tool  700  is adapted to be accessed by a plurality of devices  710  via a wireless network  708 , such as the Internet, a cellular network, Wi-Fi, or others known to those skilled in the art. The devices  710  may comprise any device, such as a laptop computer, a personal digital assistant (PDA), a smartphone, or the like, adapted to communicate over the wireless network  108 . Alternatively, the inspection tool  700  may be provided in part or in its entirety directly on devices  710 , as a native application or a web application. It should be understood that cloud computing may also be used such that the inspection tool  700  is provided partially or entirely in the cloud. In some embodiments, the application  706   a  may be downloaded directly onto devices  710  and application  706   n  communicates with application  706   a  via the network  708 . In some embodiments, the inspection tool  700  may be integrated with a measurement tool and/or an image acquisition device as a downloaded software application, a firmware application, or a combination thereof. 
         [0070]    One or more databases  712  may be integrated directly into the memory  702  or may be provided separately therefrom and remotely from the server  700  (as illustrated). In the case of a remote access to the databases  712 , access may occur via any type of network  708 , as indicated above. The databases  712  may also be accessed through an alternative wireless network or through a wired connection. The databases  712  described herein may be provided as collections of data or information organized for rapid search and retrieval by a computer. The databases  712  may be structured to facilitate storage, retrieval, modification, and deletion of data in conjunction with various data-processing operations. The databases  712  may consist of a file or sets of files that can be broken down into records, each of which consists of one or more fields. Database information may be retrieved through queries using keywords and sorting commands, in order to rapidly search, rearrange, group, and select the field. The databases  712  may be any organization of data on a data storage medium, such as one or more servers. 
         [0071]      FIG. 8  is an exemplary embodiment for an application  706   a  running on the processor  704  of the inspection tool  100 . The application  706   a  illustratively comprises a data acquisition module  802 , a comparison module  804 , and a display module  806 . The data acquisition module may be configured to acquire measurement data, tolerance data, graphical data, impact data, risk data, mathematical formulas, parameterized models, images of components, and any other type of data that may be used by the inspection tool. This data may be acquired by manual input, for example by providing the graphical user interface  302  with an input area for receiving data, as per the example of  FIG. 3 . It may also be acquired locally from memory  702  or remotely via network  708  from the databases  712  and/or from another entity, such as a measurement tool, an image acquisition device, one or more of the devices  710  or another external server having data stored thereon. 
         [0072]    The comparison module  804  may be configured to compare the measurement data to the tolerance data for at least one feature of the component and determine a pass/fail status based on the comparison. In some embodiments, the comparison module  804  may also be configured to transform the measurement data into various parameters, as per the example with the sweep angle and dihedral angle for the H-stab. In some embodiments, this transformation may be performed by the data acquisition module  802  and the parameters are provided to the comparison module  804 . The comparison module  804  is thus configured to receive, from the data acquisition module  802 , the measurement data (or parameter data) and the tolerance data for the purposes of comparison. 
         [0073]    Once the pass/fail status has been established, the display module  806  is configured for displaying the pass/fail status for the at least one feature and an impact resulting from the fail status. The comparison module  804  may communicate with the data acquisition module  802  in order to retrieve the proper impact based on the result of the comparison. For example, if the dihedral angle is too large, the h-stab may clash with the fuselage. If the dihedral angle is too small, there may be a gap between the h-stab and the fuselage. The data acquisition module  802  is thus configured to acquire the appropriate impact and communicate it to the display module  806  for display on the graphical user interface. In some embodiments, instructions to retrieve the appropriate impact may come directly from the display module  806  once it has received the comparison results from the comparison module  804 . 
         [0074]    In some embodiments, the data acquisition module  802  may also be instructed by the comparison module  804  or the display module  806  to retrieve a risk level associated with the result of the comparison for the at least one feature. As indicated above, the risk level may be correlated with the tolerance for the at least one feature and thus determined once the comparison between the measurement data and the tolerance data have been made. In some embodiments, the risk level is assigned by the comparison module  804  or the display module  806  on the basis of the comparison results. 
         [0075]    In some embodiments, the display module  806  is configured to provide a graphical representation of the measurement data, either the raw data itself or a parameter based on the measurement data. The display module  806  may be configured to select an appropriate image of the component, including a proper view to illustrate the feature, and to process the measurement data such that it may be displayed on the image of the component. Processing of the measurement data may comprise extracting the values as measured, amplifying them accordingly, recalculating the points of interest and tracing lines on the image of the component. The display module  806  may also be configured to display the tolerances graphically with the measurement data. The display module  806  may be configured to provide any or all of the information illustrated in the graphical user interfaces  402 ,  502 ,  602 , including but not limited to raw measurements, calculated parameters, tolerance data, risk level, deviation from tolerance data, and graphical representations.
