Reverse Engineering

During the phases of defining the final shape of a product, manual modifications of the models are usually performed. Designers and Specialized technicians generate a physical model based on the drawings or sketches delivered by the designers. This model is then modified by technicians and designers in order to develop the product and achieve the final aesthetic and functional criteria.

To industrialize the created model , there is a need to  input the  achieved geometry  into a Computer Aided Design  (CAD system). Traditionally this process has been done in very different ways. Initially it involved manual measurement using calipers and templates with the problems of slowness and lack of precision involved. More recently, Coordinate Measuring Machines (CMMs) have been used to control the system through a computer. It is a useful system but it has a few  drawbacks like: although the accuracy achieved is very high it is not  appropriate for a mass capture of points because of it is very slow and is not suitable for soft or deformable objects since it requires physical contact with the surface to be measured.

To solve such problems, non contact optical scanners have appeared on the market being the white light scanners such as the Sidio system. This system fits the best thanks to its features of speed, accuracy, resolution and portability.

Measurement with the SIDIO optical system allows you to:

verify the entire piece without the need to manufacture it
use special tools for non-contact measurement.
use thickness and strain gauges that show the result with intuitive color maps that facilitate the work of engineers.
align the measurements with CAD using different techniques such as:
best-fit, benchmarks (RPS), and so on.
measure objects separately and assemble them together.
take it anywhere, thanks to its portability, it can be taken directly to the production lines.
