Machine for the laser working of profiles and method for carrying out an inclined cutting operation on a profile by means of this machine

Machine for the laser working of profiles (P), comprising

• a working head (10) for emitting a focussed laser beam to carry out a working operation, such as in particular a cutting operation, on a profile (P) to be worked extending along a longitudinal axis (x), the working head (10) being translatable in a plane perpendicular to said longitudinal axis (x) and being also tiltable about an axis of oscillation (t) perpendicular to said longitudinal axis (x),
• a feeding device (14) for moving the profile (P) to be worked along said longitudinal axis (x),
• a support and guide device (12) for supporting and guiding the profile (P) to be worked as this latter is being fed during the working operation by the feeding device (14) towards the working head (10), the support and guide device (12) being translatable along said longitudinal axis (x), and
• an electronic control unit for controlling the movements of the working head (10), of the feeding device (14) and of the support and guide device (12) according to predetermined logics,
• wherein the electronic control unit is arranged to control the movements of the feeding device (14) and of the support and guide device (12) along said longitudinal axis (x), while an inclined cutting operation is being carried out on the profile (P), such as in particular to make a flared hole (H), in such a manner that before starting the working operation the support and guide device (12) is positioned in a given starting position along said longitudinal axis (x) relative to the working head (10) and then, during the working operation, the support and guide device (12) is moved along said longitudinal axis (x) integrally with the feeding device (14), and hence integrally with the profile (P), said integral movement of the support and guide device (12) with the feeding device (14) being limited to that portion of the movement of the feeding device (14) which is required to compensate for tilting movements of the working head (10) about said axis of oscillation (t).
