A data interface device for data transmission between a numerically controlled machine tool and external data processing device, including: a control interface unit for data transmission with a control device of the machine tool and communications unit for data transmission with the external data processing device. Stored configuration data specifies a communication protocol used by the control device from a first group of communication protocols and a communication protocol used by the external data processing device from a second group. The control interface unit uses any protocol from the first group of communication protocols for data transmission and selects the communication protocol used by the control device for data transmission with the control device. The communications unit uses any protocol from a second group of communication protocols for data transmission and selects the communication protocol used by the external data processing device for data transmission with the data processing device.

Data interface device for use on a numerically controlled machine tool

A numerically controlled machine tool for machining a workpiece is provided. The machine tool includes a work spindle, at least one feed axis, and a device for collision monitoring on said machine tool, wherein the device for collision monitoring includes a collision sensor mounted on a machine part of the machine tool, collision detection means for detecting a collision of machine parts of the machine tool when a measuring value detected by the collision sensor exceeds a collision limit value, and signal output means for outputting a stop signal for stopping the at least one work spindle and the at least one feed axis, of the machine tool when the collision detection means detects a collision. The machine tool includes a unit for determining the collision limit value on the machine tool.

Machine tool comprising a device for collision monitoring

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

A method for measuring a program-controlled machine tool using a measuring sphere. According to this method the measuring sphere having known dimensions is positioned on a machine part. A sensing element installed in the machine is moved to a selected initial position in which it is located approximately 10 mm above the vertex section of the sphere. Then the sensing element is repeatedly moved until it contacts various points on the surface of the sphere, and the coordinate values of those points of contact are input into the controller. Thereafter the spatial position of the center of the sphere is calculated and compared with target values stored in the controller.
