A process for shaping a part (12) of the turbine vane type, includes providing a part (12) comprising a blade (14) in an initial shape, providing a nominal definition representing the part in a nominal shape, comparing the initial shape with the nominal definition to determine compliance or non-compliance, for a non-compliant datum, determining a force to be applied to the part to deform said part, applying a force to obtain the part in a deformed shape, comparing the deformed shape with the nominal definition to determine compliance or non-compliance, and training a self-learning algorithm (82).
