A machine tool includes a speech input unit that accepts speech from an operator as input, a speech recognition unit that recognizes the speech input into the speech input unit, a status determination unit that determines an operating status of the machine tool when the speech is input into the speech input unit, a display unit, a storage unit that stores a plurality of screens, and a screen selection unit that selects a screen according to a combination of the speech recognized by the speech recognition unit and the operating status of the machine tool determined by the status determination unit from among the plurality of screens, and causes the display unit to display the selected screen.

In a method for producing and/or machining a non-conical face of a workpiece defined by a segment of a cone, in particular a sealing face of a multiple-eccentric shut-off valve, using a machine tool having at least two linear axes and at least one rotary axis controlled by a numerical controller for generating a relative movement between a tool and the workpiece, a cycle is provided on the numerical controller and retrieved by a user of the machine tool. The user parameterizes the cycle, whereafter a part program is generated by the cycle for execution by the numerical controller. The executed part program generates the relative movement along a path determined by the part program to produce and/or machine the face of the workpiece.

A control device controls a tool having a memory and removably attached to a machine. The control device includes a tool information reading unit that reads at least one of tool setting information and tool status information written in the memory of the tool, and a tool setting unit that sets the tool on the basis of at least one of the read tool setting information and tool status information. The tool is driven by a motor having an encoder, and the memory is attached to the encoder.

For an improved management of a postprocessor, for machining with a machine tool, a computer-implemented method includes providing toolpath data for machining a workpiece with a tool along a corresponding toolpath. The tool is comprised by a machine tool that is numerically controlled by a control device. Sample machine code is provided. Atrial postprocessor software component for determining machine code using toolpath data is provided. Trial machine code is determined using the trial postprocessor software component and the toolpath data. A sample code architecture of the sample machine code and a trial code architecture of the trial machine code are determined. Characteristics of the sample machine code are determined by comparing the sample code architecture with the trial code architecture, and a new postprocessor software component is determined by incorporating the characteristics into the trial postprocessor software component.
