"3D LASER SCANNING IS THE FASTEST, MOST ACCURATE WAY TO ACQUIRE 3D DIGITAL DATA FOR REVERSE ENGINEERING" www.engineeringnews.co.nz 21 designs. The output of a 3D scanner is a point cloud. A point cloud is simply thousands or millions of X,Y,Z coordinates, each coordinate being a measurement of the scanned subject. Reverse engineering is the term commonly used to describe the process of converting or re-engineering a point cloud into a 3D CAD model. Geomagic Wrap delivers an easy-to-use, fast, accurate path from point clouds to 3D polygonal mesh and geomagic Design X to surface models that can be used for engineering, manufacturing and industrial design. Once a designer reverse engineers an object, Geomagic DesignX software can transfer the model natively into most major CAD software packages. The result is a native, full-parametric CAD model with a fully editable feature tree. Geomagic software is the key to creating fully-parametric CAD models from scan data. REVERSE ENGINEERING TECHNIQUES There are two main approaches to reverse engineering. The first method results in a 3D model that matches the physical object as closely as possible. The second method results in a 3D model containing the design intent. Design intent models are generally created in the case of a heavily used part, a poorly manufactured part, or a handmade model. It is also possible to reverse engineer an object where some areas match the original and some areas are altered for design intent purposes. VERIFICATION AND VALIDATION 3D scanning provides the ideal solution for measuring, inspecting, and troubleshooting the shape and dimensions of an object. Engineers and designers are often given the challenging task of determining why a product is not fitting or functioning properly. Determining the cause of a problem is difficult with traditional measurement instruments. Kreon 3D scanners provides a clear picture of an object. Defects such as warp, twist, and wear become apparent when the scan data of a manufactured part is compared to the original CAD model. Geomagic Control X, 3D inspection software provides a comprehensive metrology software platform that delivers powerful tools. Geomagic Control X, generates colour deviation maps. The deviation map colours red, orange and yellow describe areas with larger deviation from the CAD file. Cyan and blue colours describe areas with too little deviation. In addition to colour deviation maps, Geomagic software contains the functions for full part layout with standardised geometric dimensions and tolerances (GD&T). Implementing Kreon 3D scanning into the design process gives a company many advantages over its competition. In addition to efficiencies in product design departments, Kreon 3D scanning offers cost and time savings for manufacturing and quality control.
