Operator-defined avoidance of chatter

A control program for a control device of a machine tool, wherein the control program is embodied on a non-transitory computer-readable medium and comprises machine code, which when loaded into a memory of the control device and executed by the control device, causes the control device to

• store predefined rules, wherein the predefined rules define modifications to machining of a workpiece when undesired vibrations occur during the machining;
• receive a target machining with specified machining parameters, according to which the workpiece is to be machined by the machine tool;
• receive via a first interface embodied as a human-machine interface from an operator or via a second interface to a memory device arranged outside the control device and read by the control device, a selection of the predefined rules, a parameterization of the predefined rules, or a specification of a sequence of the predefined rules, the parameterization comprising a specified hold time, and executing the selected predefined rules in the specified sequence;
• control the machine tool so that the workpiece is machined by the machine tool;
• during the machining of the workpiece by the machine tool, evaluate sensor signals captured by a sensor disposed on the machine tool to check whether or not the undesired vibrations are occurring;
• when the undesired vibrations do not occur, carry out the machining according to the target machining, and
• when the undesired vibrations occur, modify the machining according to the predefined rules and maintain the modified machining unchanged during the hold time, and following expiration of the hold time and when the undesired vibrations no longer occur, returning to the target machining with the specified machining parameters.
