The invention is directed to a machine tool W having a control device for controlling the operating modes of the machine tool W. The control device comprises an operating unit B for operation of the control device by a user and a safety controller S for actuating the various machine areas M of the machine tool W. By means of the operating unit B, it is possible to select machine areas of the machine tool W and to define an operating mode for the selected machine areas M. The selected machine areas M and associated operating mode are transmitted to the safety controller S. As a result of this type of actuation of the machine tool, safe operation is possible during installation and service work on the machine tool.

Machine tool with control device

Apparatus for monitoring and providing visual representations of the operating conditions of machine tool parameters, in particular for program-controlled turning, milling, and drilling machines, which have a machining unit displaceable in a plurality of coordinate axes, in which a work spindle for exchangeable receiving a machining tool and an electric motor for driving the work spindle are mounted. The machine tool includes a control unit and means for monitoring the operating state of the machine tool. The monitoring apparatus has at least one sensor for detecting at least one operating parameter of the machine tool. An evaluating unit is connected to both the sensor and the control unit and processes the measurement values detected by the sensor. An optical display is provided in the direct viewing range of the operator, which viewing range includes the machine operating spindle, tool holder, tool, and workplace. The optical display can display a normal, a critical, and a dangerous operating state of the machine tool in accordance with the data from the evaluating unit.

Apparatus for monitoring and providing visual representations of the operating conditions of machine tool parameters

An apparatus for controlling operational functions of a machine tool, comprising a device for switching on or off a main power supply and at least one device for determining a switch-off time of an operational function of the machine tool in dependence of a selectable criterion.

Apparatus for controlling operational functions of a machine tool

The invention relates to a machine toolcomprising a plurality of operation functions and a selection device-for selecting one or more operation functions by a user. The machine toolreceives data from a mobile data carriervia a reception device, on the basis of which it may be determined which operation functions may be performed by the user. In this process, an access control devicegrants the user access to only those selected operation functions he or she is authorized to perform.

System for controlling user access to a machine tool

A monitoring procedure and a monitoring installation for machine tools with a motor-driven work spindle and a separate protection device. The actual mass inertia moment of a tool fitted into the work spindle is determined by measurement and compared with a mass inertia moment calculated from the data of the tool. In addition, a predetermined parameter of a tool fitted into the work spindle is compared with that of the maximum parameter for the tool which is dependent on the strength of the protection device. The work spindle will be driven at the predetermined desired speed of rotation only if the actual mass inertia moment agrees with the calculated mass inertia moment and the predetermined parameter is smaller than or equal to the maximum parameter predetermined by the strength of the protection device.
