The present disclosure relates to a method and apparatus for cycle-based programming of a control program for a numerically controlled machine tool at a control apparatus of the machine tool. Geometrical features, which have been detected and/or identified within a data analysis processing performed on the basis of workpiece data including a 3D workpiece model, each detected and/or identified geometrical feature being associated with a respective predetermined machining operation, are associated with a respective machine control cycle which is associated with a respective predetermined machining operation with which the respective associated geometry feature is producible. Further, one or more user-selectable options for cycle-based programming of the control program for the machine tool are provided by a graphical user interface on a display of a control panel of a control apparatus of the machine tool, each user-selectable option enabling a user to select a respective one of the machine control cycles being respectively associated with a respective one of the detected and/or identified geometrical features.

A drive device having an electric motor with a device for field oriented control of the electric motor and a method for operation thereof is disclosed. An error monitoring of a transducer on the electric motor is achieved by a comparator device for comparing a transducer signal of the transducer on the electric motor with a calculated parameter of the field oriented control, the comparator device recognizing a transducer error and/or a coupling error. The coupling error relates to a coupling for mounting the transducer on the electric motor.

Error recognition by evaluation of parameters of the field oriented regulation

A control device for controlling the movement of a machine determines a base position set value according to a given base track in space. By limitation of a base element of a machine therewith, the above is hence positionally moved along a base track. The control device further determines a corresponding current supplementary end position in space using the base position set value. The control device also determines a supplementary position set value from a given fixed supplementary start position in space and the current supplementary end position. By limitation of a supplementary element of the machine thereto, the above is thus displaced along an current supplementary track from the supplementary start position, to the current supplementary end position.

After an emergency braking operation is released in the case of a numerically controlled machine, the path calculated by the interpolator continues to be traveled, so that braking takes place on this path in the interpolation clock cycle. To determine the braking-interpolation points (P.sub.iB), a factor k is defined for each axle, which factor fulfills the condition of at least one axle being decelerated by a maximum amount and the remaining axles being decelerated more slowly.

Method for a time-optimal, true-to-path braking of axle drives of

A one-dimensional, actual-value-specific path parameter F.sub.I (t) is derived from a motional function F.sub.B (t) to trigger switching functions related to position during the movement along a trajectory path of a numerically controlled system, for example a robot or a machine tool. This allows triggering of a switching operation such as switching on a welding or bonding tool with high precision at the actual position of the tool.
