    摘要: A control device for a machine tool comprises a control section controlling the relative rotation and feeding of a cutting tool and a material, performing cutting with vibration of the cutting tool relative to the material by combining a forward feed movement in the machining direction, and a return movement in the counter-machining direction. A return movement setting section sets a pulse-like signal including a command for moving a cutting tool in the machining direction and a command for the return movement. A forward feed setting section makes the cutting tool reach a change point by combining the movement in the machining direction on the basis of the return movement setting section and the forward feed movement. A pulse-like signal is formed in sine waveform with an inflection point, and a phase of the inflection point is set to a value different from a phase of the change point.

    摘要: A pressing tool for plastically deforming a workpiece is described. The pressing tool includes a housing and an electric motor for actuating the pressing tool. The pressing tool also includes an instrument seat which is adapted to receive an interchangeable instrument head at the housing. The pressing tool also includes a mechanical safety element which is arranged in a manner that is movable from an open position, in which an instrument head may be inserted into the instrument seat, into a closed position, in which the instrument head is locked in the instrument seat. The pressing tool additionally includes a mechanical actuating element which may interact with the safety element in order to be able to cause the pressing tool to be enabled for a pressing process.

    摘要: A system and method for collaborative manufacturing system operation for a linear motor conveyor system including one or more moving elements. The system includes: at least two safety gates arranged on the linear motor conveyor system creating a collaborative area between the safety gates. Each safety gate includes: a body; two doors, one on each side of the body; an interlock connecting the two doors such that only one door can remain open at a time; and a control system to control the safety gates in coordination with the linear motor conveyor system. The method includes: configuring an operating status, which may be non-collaborative, collaborative, or semi-collaborative modes; monitoring a safety trigger and, if activated, performing a safety action and controlling according to the type of safety trigger; monitoring if the safety trigger is removed; and if the safety trigger is removed, return to operating in the configured mode.

    摘要: A machine tool includes: a movable body that supports a tool; a feed drive unit that feed-drives the movable body; a numerical control unit that controls the feed drive by the feed drive unit to perform cutting by the tool; an acceleration sensor that is provided on the movable body and detects acceleration of the movable body; and a command unit that outputs a stop command to stop driving of the feed drive unit to the numerical control unit when the acceleration of the movable body exceeds a threshold value set in advance on the basis of an output of the acceleration sensor. The command unit sets the threshold value to a first threshold value in a cutting control state, and sets the threshold value to a second threshold value lower than the first threshold value in a feed control in a non-cutting control state.

    摘要: The invention relates to an electric machine tool comprising an electric motor, a motor control unit for operating the electric motor, an input interface for entering a target specification of an operating mode of the electric motor into the motor control unit, and a motor sensor device for detecting the operating mode of the electric motor. A slave control unit is provided, which is independent from the motor control unit and communicatingly connected to the motor sensor device and the input interface and designed to compare the operating mode of the electric motor detected by the motor sensor device with the target specification entered via the input interface, and to influence the operating mode of the electric motor in case of a defined deviation of the operating mode from the target specification by means of a control device.
