A method for pushing, with a force a tool at the end of an articulated arm against a surface with a normal, including the steps of: positioning the tool against the surface; applying an increasing force to the tool until reaching a value, corresponding to a fraction of the force, the value of the applied force being monitored; measuring the orientation of the tool with respect to the normal, after having reached the force value; and redirecting the tool so as to recover its initial orientation with respect to the normal. Iteration is carried out to proceed, by repetition of steps to, while progressively increasing the force at each iteration, and until reaching the force value, the increase increment between two successive steps being smaller than a determined value.

Disclosed is a drilling tool intended to cooperate with a tooling including at least one guide orifice, including: a hollow nose part, through which a drilling member is intended to pass; and a gripping clamp, slidingly mounted on the hollow nose part, the sliding of the gripping clamp rearward along the hollow nose part leading to its radial expansion towards the outside. The distal end of the gripping clamp includes a bead protruding radially towards the outside, configured to ensure the stopping in translation of the drilling tool with respect to the tooling, by bearing against a wall of the tooling surrounding the guide orifice, when the gripping clamp is expanded radially towards the outside.

An orbital drilling device includes, on the same frame: a motor rotating a cutting tool on itself; a first, interior, eccentric, receiving the motor, mounted so as to be able to rotate; a second, exterior, eccentric, receiving the first eccentric, mounted so as to be able to rotate; a reference body, secured to the frame, receiving the second eccentric, mounted so as to be able to rotate; a first unit for driving the first eccentric; a second unit for driving the second eccentric, simultaneously with the rotation of the first eccentric; and a controller configured to reproduce any path of the cutting tool in the zone by continuous control of the angular offset between the first eccentric and the second eccentric.
Drilling tool (1) intended to cooperate with tooling (10) comprising at least one guide orifice (11), comprising: - a hollow nose piece (2) through which a drilling member is intended to pass, - a collet chuck (3), mounted in a sliding manner on the hollow nose piece (2), the sliding of the collet chuck (3) towards the rear along the hollow nose piece (2) causing it to expand radially outwards. The distal end (E31) of the collet chuck (3) comprises a bead (33) protruding radially outwards, configured to stop the movement in translation of the drilling tool (1) with respect to the tooling (10) by bearing against a wall of the tooling (10) surrounding said guide orifice (11), when the collet chuck (3) is expanded radially outwards.
Method for causing a tool (1) at the end of an articulated arm (2) to press with a force (F) against a surface (3) of normal (N), com¬ prising the steps: (a) positioning the tool (1) against the said surface (3), (b) applying to the tool (1) a force that increases until it reaches a value (Fn) corresponding to a fraction of the force (F), the value of the force (Fn) applied being controlled, (c) measuring the orientation of the tool (1) with respect to the normal (N) after having reached the said force value (Fn), (d) re-orientating the tool (1) so that it regains its initial orientation with respect to the normal (N), which method proceeds by successive iterations, repeating steps (b) to (d), progressively increasing the force (Fn) on each iteration, and until the force value (F) is reached, the incremental increase (AFn) between two successive levels (Fn) being below a deter¬ mined value.
