  • Device and method for finishing a solid-propellant charge
    Patent number: 12246433
    Abstract: A process for removing webs formed on a wall of a central channel of a propellant charge, the process including removing webs by levelling the wall of the central channel of the propellant charge with a levelling tool installed on an articulated robotic arm during which the movements of the robot arm are controlled by a user interface which includes a controller configured to be used by a user; a force sensor measures the force applied by the levelling tool; a control unit connected to the force sensor regulates the movements of the robot arm by maintaining the force applied by the levelling tool below a first predetermined force threshold, the control unit also regulating the movements of the robot arm by maintaining a movement speed of the levelling tool which is below a predetermined speed threshold value.
