Abstract
A machine tool for machining workpieces has a machine frame, at least one component part which can be moved along a movement path by means of a power-operated drive unit, at least one frame part, which is connected to the machine frame and which is arranged at an end position in the movement path of the component part, and at least a first stop, via which the component part in contact with the frame part when said component part is in the end position, wherein the first stop lies outside the movement path.
Claims27
A machining device, comprising
- a machine frame,
- a power-operated drive unit, the power operated drive unit configured to move at least one component part relative to said machine frame
- along a movement path until the at least one component part rests against at least one frame part connected to said machine frame and arranged at an end position of movement of the at least one component part in the movement part via at least a first stop,
- the power-operated drive unit further configured to exert a further force on the at least one component part to push the at least one component part while being in the end position towards the frame part,
- wherein the first stop is situated between the at least one component part and the frame part, at least when the at least one component part is in the end position, wherein said first stop lies outside of the movement path, and
- a controller that detects, after the at least one component part is in the end position, whether a movement of at least one of:
- the at least one component part and/or the drive unit takes place, and outputs a fault message if a movement of either is detected.
A method for operating a machine, said machine comprising a machine frame, a power-operated drive unit, at least one component part moved by said power-operated drive unit relative to said machine frame along a movement path, at least one frame part connected to said machine frame and arranged at an end position of movement of said component part in the movement path, and at least a first stop, said first stop being situated between the component part and the frame part, at least when the component part is in the end position, said method comprising the steps of
- a) moving said component part into said end position by means of said drive unit, until said component part rests against said frame part via said first stop,
- b) exerting a further force on said component part by means of said drive unit, thereby pushing said component part while being in the end position towards the frame part,
- c) detecting whether a further movement of at least one of the component part and in the drive unit takes place, and
- d) outputting a fault message if a movement is detected in step c).
