By Nel PreTech
Reverse engineering services, part digitization, and 3D modeling are three fundamentally linked processes. To be able to provide services in any one, you must excel at all three. If your goal is a usable CAD model or a 3D data set, Nel PreTech has the tools and expertise. We are distinguished in this industry because of our skilled team, our access to the most cutting-edge equipment and software available, our commitment to accuracy, and exceeding customer expectations. NPC has the PEOPLE, PROCESS, and PLATFORM to see the 3D CAD modeling process through from start to finish. Common Uses of Reverse Engineering - Re-engineering or improved functionality of your own products - Analysis of competitor parts - Obtaining base-model geometry for design purposes (This geometry can be used to create new blueprints or CAD designs similar to the original object.) - Replacement of tooling that otherwise cannot be reproduced Benefits of Reverse Engineering Part digitization, while very useful, could be limited to partial data or rough data displayed as a point cloud. While this data is useful for inspection purposes, parametric modeling provides information relevant to the original design intent of the part. This includes a solid CAD model or even blueprints. The model can show a product with imperfections removed and/or a full feature design tree. Models can be provided in a.stp,.iges, or native CAD format and can be manipulated within CAD software such as Solidworks, Pro-E, IDEAS, AutoCAD, and others. Digitization / Color Mapping Process Our part digitization process is based on the capabilities of scanning CMM’s, scanning vision systems, computed tomography (CT scanning), lasers, blue light scanners, and other tools. This gives Nel PreTech the ability to produce highly accurate and repeatable measurements. It’s this capability that is the cornerstone of our reverse engineering and 3D modeling services. Color mapping allows information taken from industrial CT, structured light, or other digital scans to be compared to a nominal CAD model. Comparisons can also be made to other existing part data sets. You'll get the option of user-definable color patterns for easy analysis of surface variations.
