Abstract

L'invention concerne un procédé d'usinage de la surface d'une pièce, une configuration de surface de premier ordre (1) étant constituée par un premier procédé de finition, par exemple un usinage par enlèvement de copeaux. Les configurations de surface de deuxième et/ou troisième ordre formées sont alors modifiées au moyen d'un usinage au laser, la configuration de surface de premier ordre (1) restant sensiblement inchangée. De cette manière, il est possible de constituer la configuration de surface de premier ordre (1) sensiblement indépendamment de la configuration de surface de troisième ordre et/ou de la configuration de surface de deuxième ordre (2) et ainsi de régler le degré de réflexion.
