Reverse engineering enables the duplication of an existing part by capturing the component’s physical dimensions, features, and material properties. There are a wide range of reasons for reverse engineering an object, including:
Legacy Components – For many components that were designed and manufactured years ago, there are no existing 2D drawings or 3D CAD data from which to reproduce the object. Here, reverse engineering is a vital means to gain the information to recreate the product.
Original Equipment Manufacturer (OEM) issues - If the OEM is no longer trading or has lost design measurements, then Reverse Engineering will supply the vital product information to continue manufacturing of that object.
Design Development, Part Testing & Analysis – Through reverse engineering, a 3D product can be quickly captured in digital form and remodelled or analysed in order to achieve improved design iterations. Competitor Analysis – Any organisation can analyse competitor products through reverse engineering. Bespoke and Ancient objects – Where there is no information about the dimensions of an object except for the physical item itself, the quickest and most reliable way to reproduce it will be by reverse engineering. Where a product is organic in shape (not a standard geometry such as cuboid or cylindrical), designing in CAD may be challenging as it can be difficult to ensure that the CAD model will be acceptably close to the sculpted model. Reverse engineering avoids this problem as the physical model is the source of the information for the CAD model. Modern manufacturing – methods such as Additive Manufacturing rely on reverse engineering.
The 3D Scanning Process: Information Acquisition by means of 3D Laser Scanning 3D Laser Scanning Process An item that will be laser examined is put on the bed of the digitizer. Specific programming drives the laser test over the outside of the item. The laser test extends a line of laser light onto the surface while 2 sensor cameras ceaselessly record the changing separation and state of the laser line in three measurements (XYZ) as it clears along the article. Coming about Data The state of the article shows up as a large number of focuses called a "point cloud" on the PC screen as the laser moves around catching the whole surface state of the item. The procedure is quick, getting together to 750,000 focuses every second and exact (to ±.0005″).
