Abstract: A device for setting a temporary fastener. The temporary fastener includes a body with an expandable/retractable end and a rotary element capable of being driven in rotation so as to cause the expandable/retractable end to expand/retract. The device includes a support module that is able to house a temporary fastener and has a holder for holding the temporary fastening inside the module. The holder is movable between at least: a locking position in which the holder is deployed inside the module so as to cooperate with a temporary fastener placed in the module in order to prevent it from moving in translation inside the module, and a rest position in which the holder is retracted so as to allow a temporary fastener to pass through the module.

Abstract: A multi-task device includes at least: a rivet support module able to contain a rivet and/or a temporary fastener support module able to contain a temporary fastener; a device for introducing a rivet or temporary fastener into the modules at at least one loading station; and a device for moving the at least one module to a work station for setting a rivet or temporary fastener in a hole provided in a structure to be worked on. The multi-task device includes a device for checking compliance of the rivet or temporary fastener depending on at least one predetermined compliance criterion, and a device for discharging, to a disposal zone, a rivet or temporary fastener identified as non-compliant by the device for checking.

Abstract: A drill including a drill spindle capable of driving a cutting tool in movement. The drill has at least one channel for distributing a lubricant to the cutting tool, a pump to supply the channel with lubricant and control element(s) for controlling the flow rate of the pump. Such a drill further has mechanical element(s) for determining at least one piece of information representing the torque exerted on the spindle along its axis during drilling. The control element(s) act on the flow rate of the pump as a function of the torque exerted on the spindle along its axis during drilling.

Abstract: A method is provided for assessing wear of a drill bit throughout its use for carrying out the drilling of elements to be drilled constituted by at least one layer and at least one material. The wear of the drill bit expresses its capacity to perform a drilling that meets at least one criterion of quality of a drilling. The method includes at least: measuring or detecting at least one parameter having an effect on the wear of the drill bit, the parameter being chosen from: the depth of drilling performed by the drill bit, and the entry of the drill bit into the element to be drilled; and determining at least one state of wear of the drill bit, each state of wear being determined as a function of one of the parameters and being characteristic of one of the criteria of quality of a drilling.

Abstract: A method for drilling an element to be drilled by a drilling device and a cutting tool including drill margins and cutting edges. The method includes determining at least one load value representing overall drag due to internal friction of the drilling device and to friction of drill margins in the element to be drilled. Determining includes: stopping a drilling operation in progress; partial retraction of the cutting tool on a predetermined distance, the predetermined distance being chosen such that the cutting edges are no longer in contact with the element to be drilled; driving the cutting tool with predetermined cutting parameters; measuring at least one load value during the driving of the cutting tool with the cutting parameters before its cutting edges again come into contact with the element to be drilled and after stabilization of the load values, the measured load value representing the overall drag.

Abstract: A drilling device with automatic or controlled feed speed. The drilling device includes a casing that houses a drilling spindle that is to drive a cutting tool in motion to drill a workpiece having a target surface. The spindle is tiltable inside the casing relative to the axis of the casing. The device has a self-alignment, which self-aligns the spindle relative to the target surface. The self-alignment moves the spindle into a position in which its axis is essentially perpendicular to the target surface under the effect of an application of a thrust force of the drilling device against the target surface essentially along the axis of the casing.

Abstract: A controlled feed speed drilling machine includes an output shaft for driving a cutting tool in motion. The output shaft is connected to first and second motors by a transmission, which includes a rotationally driving ring and a tapped drive nut. The driving ring is rotatable along the longitudinal axis of the output shaft via the transmission and the first motor. The output shaft is rotationally linked to the driving ring and is mobile in translation relative to the driving ring along the longitudinal axis via the transmission and the second motor. The tapped drive nut rotates along the longitudinal axis relative to the output shaft via the transmission and the first motor. The translation speed VT of the output shaft along its longitudinal axis is equal to the product of the rotation frequency FR of the second motor and a constant k according to VT=k. FR.
