Abstract: A machining apparatus is borne by an articulated arm and includes: a casing defining an opening to be placed by the articulated arm in a machining position so the opening faces the surface to be machined; at least three bearers attached to the casing to rest against the surface to be machined in the machining position; an attachment system fixing the casing to the surface to be machined; at least one support mounted to move with respect to the casing, and a machine-tool mounted on the support; and at least one position sensor providing position parameters representing a relative position of the surface to be machined with respect to the casing. Also included is a control system operating the support and to move the machine-tool with respect to the casing according to a movement instruction, the control system being designed to calculate the movement instruction using the position parameters.

Abstract: A portable drilling and/or boring machine, for workpieces, in particular workpieces that make up aeroplane structures, such as airframes, wings, cabin, etc., the machine including a jig busing for guiding a machining tool, an expansible clip for blocking the jig bushing in an opening of a screen positioned on and secured to the workpiece, the screen constituting a drilling jig, and means for moving the expansible clip in order to clamp and unclamp the jig bushing and secure the machine relative to the screen, the means for moving the expansible clip relative to the jig bushing including an electric motor, the torque and position of which are controlled.

Abstract: The present disclosure relates to a sub-assembly of a drape-forming head (20), comprising, downstream, at least one member (23) for depositing the prepreg strip, at least one roller (30, 30?) for compacting the prepreg strip, and a device (10) for checking the play between the strips, consisting of a profilometer including a camera (13), a laser light source (11) projecting a line of light onto the surface to be checked, and a prism (16) arranged near the surface to be checked, in the axis of the camera (13), so as to send, to the camera (13), the image of the projected line of light that reaches the camera at a certain angle. The camera (13) and the light source (11) are placed side-by-side in an offset housing (18) arranged remotely from the compacting rollers (30, 30?), the prism (16) being connected to the housing (18) and to the camera (13) via an elongate casing (19) vertically arranged between the compacting rollers (30, 30?).

Abstract: An automatic method for changing the machining reference frame on a machine for machining parts from bars, notably extruded or molded profile sections, the part to be machined being held during its machining by at least two distinct and independent clamping means each having a longitudinal movement and a rotation on an axis parallel to the long axis of the part to be machined allowing for a relative angular and longitudinal displacement of one relative to the other, a method whereby, in order to proceed with a change of reference frame, one of the clamping means releases the part to be machined and disengages therefrom to turn freely about the long axis of the part independently of the other clamping means, then aligns itself angularly on new clamping references of the part before retaking the latter and allowing for a change of grip by the other clamping means.

Abstract: A drilling and milling machine, in particular for component parts of aircraft structures, comprising electric motors powered by a power unit and controlled by a control unit, said machine being connected to a general power supply; the power unit and the control unit are rigidly connected to the machine and the general power supply is separated from the machine.
