It also offers services for Quality Control and Inspection of complex free form parts.Reverse Engineering is a very wide term generally used to describe a process of generating engineering parameters from existing product. We confine our scope to describe reverse engineering in context to generating dimensional parameters of products. The process of Reverse Engineering can be broken up into following constitute parts.3D Scanning and White light Scanning, Surfacing, Solid Modelling.Photogrammetry is a co-ordinate measuring technique to generate 3D-co-ordinates of points and features from a group of photographs taken from different points in space. Surfacing is a process of fitting surface entity in a cloud of points ensuring specified geometric tolerances. Surfacing is required in order to use the scan data for machining smooth surfaces mainly for die/mould production, analysis, digital mockups or packaging purposes.

Inputs vary widely from rough concept to existing working part, needs vary from new parts development to life extension program, simple refurbishment or a facelift. In all cases a vital requirement today is to deliver the prototype in digital form. This is where APM offers CONCEPT to CAD. A physical prototype is created after a design concept is finalized based on renderings and then it is converted to CAD through the process of Reverse Engineering. Tue, 03 Mar 2009 02:22:32 GMT Tue, 03 Mar 2009 02:22:32 GMT http://whitelightscanning.com/php/showContent.php?linkid=12andpartid=9 Measuring Systems: ATOS, TRITOP, Keywords: Computation Fluid Dynamics (CFD), CAD Comparison In the 90is, NASA started to develop the Autonom Crew Return Vehicle X-38. This vehicle is designed to bring up to 7 astronauts in an emergency case safe back to earth. For this development, flight and landing test were made from increasing dropping altitudes. From these experiments, the computer simulation can be confirmed and refined to allow an optimization of the design. Very important for this process is that the form of the actual model matches the form of the object used in the simulation (CFD, Computational Fluid Dynamics). For this reason, the actual model has to be digitized with high accuracy and high data density during the development. From these actual data, CAD data is generated, which is used in the simulation. In this application note, we show how the digitizing was done and how the data was treated to match the needs of NASA. The project was conducted by Capture 3D as a service work for NASA. Digitizing was needed for the actual X-38 test vehicle, a 80% model, approx. 33 feet long, 12 feet tall and 10 feet wide. Based on these data, multiple evaluation tasks have to be started, e.g. "As Built Vs. As Designed", generate an "As Built" surface model for CFD Analysis and determine the effects of a previously "hard landing". Tue, 03 Mar 2009 02:22:32 GMT Tue, 03 Mar 2009 02:22:32 GMT http://whitelightscanning.com/php/showContent.php?linkid=11andpartid=9 The traditional method for the acquisition of measuring data is time-consuming and generally demands to transport the tool to the measuring setup or to the measuring machine. Today, powerful digitizing systems, based on the principle of fringe projection, are an integral part of industrial process and measuring chains and constitute a good alternative. In tool and moldmaking it is important to capture the actual contour of a mold as well-fitting parts come from "wrong" molds which compensate shrinkage and springback of those parts during the production process and removal from the mold. In addition, the molds in production are subject to abrasion.

The measured data can be used in product analysis and "digital mock up" (DMU). The digitization of a full size car is a standard task for automotive design studios. For this application, Coordinate Measuring Machines or Layout Machines were usually used. Since early in 1998, these systems can be replaced by ATOS XL, a white light scanner system. In addition to the accurate and fast scanning of dense data points from the outside of the car, the ATOS system can also be used to scan the already built-in interior. This can be done in a standard car, due to the modern concept, the ease-of-use and the flexibility of the digitizing system. In this case, the measurement data of the interior and the exterior are lying in the same coordinate system.

The sensor unit projects different fringe patterns onto the object to be measured. These patterns are then recorded by two cameras. Based on the optical image equations (calibration), the computer automatically calculates the 3D coordinates for each camera pixel of the scanned surfaces with very high precision. Individual measurements are automatically transferred to a common object coordinate system using previously applied reference points. During each measurement, the software checks online for system calibration, sensor movement or any ambient changes that might affect the measurement.

Measuring tasks that so far could only be performed using tactile 3D coordinate measuring machines, measuring arms or measuring aids, can now be carried out easily and efficiently with the TRITOPCMM system as it does not require any complex and maintenance-intensive hardware.

Then in addition they have to monitor the quality of the product during its complete life cycle. For the first article inspection, the parts have to be comprehensively tested and verified to quantify the "As Built" condition. This information can be utilized to incorporate immediate design / manufacturing changes to produce a good part and can also be used as a baseline data set to monitor future part production. To ensure the production quality, the wear on the tool and form modifications of the produced parts have to be measured and visualized as early as possible, at minimum costs.

With the increasing complexity of Air Foils, Nozzles, and Impellers, simple methods of inspection are no longer acceptable. To overcome these challenges, Casting and Forging companies are now turning to Digital Inspection using Automation. Until recently the accuracy demand within the Power Generation industry precluded the use of such data collection devices. Now, with the release of the ATOS II and ATOS III measurement systems, both the accuracy and automation needs have been addressed.
