ABSTRACT:
A method is described for controlling a machine tool that has a spindle which rotates at a variable rotation speed n about a spindle axis. The spindle carries a facing head that is fitted with a tool whose radial distance V from the spindle axis is adjustable by means of a control system. The distance V and/or the rotation speed n are modified as a function of a machining operation to be performed with the tool. In order to attain a desired distance V.sub.actual, the control system specifies a reference value V.sub.ref that is smaller than the desired distance V.sub.actual by a certain correction value .DELTA.V, the correction value .DELTA.V being calculated as a function of the desired distance V.sub.actual and the rotation speed n.
