"Géo3D" research topics

The Géo3D team's activities over the past several years have concentrated on problems related to incorporating geometrical defects of real parts into the design, manufacturing and inspection stages.

The design stage involves defining the geometry of part shapes on the basis of constraints associated with the mechanism, through the specified geometry. Work performed in the area of machining is focused on guaranteeing coherence between the geometry of machined shapes and the geometrical model, by controlling the tool trajectory. Lastly, inspection activities concern dimensional metrology considerations with the objective of verifying the geometry of real shapes and so providing verification of the geometrical specifications through the associated geometry.

The team's research activities can be divided into the three following topic areas:

• Geometrical tolerancing and dimensioning
• Geometrical quality of machined parts
• Dimensional measurements and inspection
