PROCEDE DE CONTROLE DE LA GEOMETRIE D'UNE MACHINE A COMMANDE NUMERIQUE POUR L'USINAGE 5 AXES.

摘要

The method involves assembling a control tool on a tool-holder spindle (3) of a numerically controlled machine, where the tool is formed by a ball (5) positioned on rotating arm (4). The spindle and the tool are moved towards a laser beam (2a). Positions of the machine are retrieved at an instant where the tool cuts the beam. Scanning operation of the laser beam by the tool is repeated according to a predetermined program for different angular positions of the tool on the spindle and for different angular positions of the spindle around rotation axes (B, C) of orientation in a space. An independent claim is also included for a tool for implementing a method for controlling geometry of a numerically controlled machine.
