The invention relates to a method for processing a work piece by removing material with a tool in which the tool is guided over the work piece in paths. The pivoting and cambering angle of the tool is selected in every point such that the width of a tolerance zone is optimized. Within said zone, the effective zone (K) of the tool is located in a tolerance zone of the desired specified surface (Psi) of the work piece. The distance between two points (P1, Pr) is maximized, said points characterizing the furthest outlying points of the tolerance zone. As a result, it possible to produce surfaces having a high precision with a small number of paths.

L'invention concerne un procédé d'usinage de pièces par enlèvement de matière, à l'aide d'un outil qui est guidé au-dessus de la pièce à usiner, dans des voies de passage. A cet effet, dans chacun des points, l'angle de pivotement et de piqué de l'outil est choisi de manière à optimiser la largeur d'une zone de tolérance dans laquelle se situe la zone active (K) de l'outil dans une zone de tolérance de la surface théorique (Psi) voulue de la pièce. A cette fin, l'écart entre les deux points (Pl, Pr) qui caractérisent les points les plus extérieurs de la zone de tolérance, est maximisé. Ce procédé permet de produire des surfaces de grande précision avec un nombre réduit de voies de passage.
