Industrial usage of Reverse Engineering

Industrial usage of reverse engineering in various fields

Reverse Engineering is being applied to generate CAD files. Specialized software is used with CMM and a touch probe in two demonstration experiments. Advantages of the technique include immediate feedback, data reduction, direct generation of geometry and higher precision of the final product.

Reverse Engineering in manufacturing and engineering is used to find out how equipment or products are made and work.

Reverse Engineering in manufacturing and engineering is used for a wide variety of reasons. By taking apart engineering equipment or a manufactured product and discovering the materials it is made from and how it works, we can help a business determine and improve production processes, enhance product effectiveness, and protect patents.

The process is also used to discover how a ‘legacy’ (i.e very old) component or product operates and is necessary when the original technical drawings and material information are no longer available or the original manufacturer is no longer in business.

Reverse Engineering requires multidisciplinary expertise and experience when deconstructing an item.

Examples of Reverse Engineering in Industrial usage

Following are some of the examples presented to us by experts in the industry – Reverse Engineering Service (RES)

• CAD data for mould production

Classic clay modeling is still widely used during the design process for creating shapes and models.

Reverse engineering here, helps in two ways:

  • 3D Scan of clay model
  • Reverse engineering and free form modelling of the 3D Scan – STL file (Catia V5/V6)

Example: Mold-milling of a new Santa Claus, to be made of chocolate

CadMould Reverse Engineering

• CAD data for construction of injection molds

Cadmold software simulates material flow during injection moulding processes. Simulation is done on the original CAD construction file and the result of this simulation is a pointcloud with variations on the surface. This pointcloud represents the expected result of the moulding process.

Reverse Engineering Service (RES) remodels this pointcloud back to CAD data. Based on this new CAD file, the mould design can be further optimized in areas where tolerances are outside of the requested range.

Here, Reverse Engineering applies in these ways:

  • Moldflow simulation of hot plastics with Cadmold software
  • Reverse engineering with free form modelling and remodeling of parametric geometries (various software)

Example: Injection molding of plastic parts for use in hospital ventilators

Digital Jetzt funding program & investment funding up to 55% for SMEs by Federal Govt. of Germany

Image
The Federal Ministry for Economic Affairs and Energy (BMWi) supports small and medium-sized enterprises (SMEs) with the program "Digital Jetzt - Investment Funding for SMEs " so that medium-sized companies can exploit the economic potential of digitization. The program offers financial grants and aims to encourage companies to invest more in digital technologies and in the qualification of their employees. More and more medium-sized companies are recognizing: Digitization opens up new economic opportunities. In addition, digital technologies enable new business models, intelligent work and production processes, more effective customer acquisition and better networking, for example with suppliers. Digital skills and digitally trained employees are therefore a decisive factor for economic success.   “Medium-sized companies in particular can benefit from the digital age. The Federal Ministry for Economic Affairs and Energy supports you with the new funding program "Digital ...

3D Scanning Tips & Tricks for Targets

Image
  3D Scanning Tips & Tricks for Targets The EinScan 3D Scanners are very fast, accurate, and powerful machines when it comes down to scanning capabilities. The only tricky thing that can cause trouble for the users is having to put the tracking targets on the part before you can scan anything. Also the issue of having to take them off afterwards. Usually, this isn’t much of a problem for average-sized parts that are only a couple of feet across. But if the part you are scanning is too small to have targets placed on it properly or if the parts are really big, like a boat or large metal casting it can slow down the process. For the convenience of the users,  Reverse Engineering Service  by Mako GmbH have come up with ways to speed up the process of adding and removing targets. Here are some ideas you can use to help speed up your pre/post scan rituals: The easiest place to start is with the Size of the targets, either 3mm or 6mm in diameter, and how sticky th...
