LESSON 1.5: RE (Reverse Engineering)

INTRODUCTION TO THE LESSON

The concept of Reverse Engineering is based on the construction of a virtual model (3D CAD model) of an existing real object, starting from the relief of points belonging to the surface of the object.

 

WHAT YOU WILL LEARN IN THIS LESSON

At the end of the training, students will know:

  1. the main types of 3D scanners: contact or non-contact.
  2. how to scan an object.
  3. to know the steps necessary to create a digital model that includes volume, texture, and color of a real object by 3D scanning.
  4. the preparation of the object for scanning: surface treatment and positioning of the reference points.
  5. post-processing phase: processing of the point cloud to increase the accuracy of the acquisition, triangulation process, formation of a polygonal mesh to obtain the CAD model.

 SUMMARY

Thanks to this lesson you have enforced

  1. the knowledge of the steps of a RE process: analyze an existing physical part to extract CAD features and to construct a new part.
  2. the knowledge of the fundamental elements to be able to perform all system calibration, scan preparation, and post-processing steps to obtain an optimized model in a standardized format.
