Control device for operating a machine tool, in particular a milling machine or lathe, and corresponding machine tool

A control apparatus (1) for operation of a machine tool, in particular a milling machine or lathe, having a tool head that can be displaced and positioned by a motor,

• which control apparatus (1) is set up to run an at least partially freely programmable control program, and determines or co-determines the operational sequences of the machine tool,
• and which control apparatus (1) comprises a user interface (2) for manually controllable influencing of the operational sequences of the machine tool, wherein
• the user interface (2) comprises at least one control element for manually controllable changing of movements of the tool head,
• wherein
• a multi-functionally structured control element (11) is provided, which is set up, in a first usage state, to manually set or influence an advancing speed during the course of a processing phase of the tool head, and which multi-functional control element (11) is set up, in a second usage state, to manually set or influence a rapid speed during the course of a rapid-speed phase of the tool head, and wherein
• the multi-functionally structured control element (11) is structured as a rotary control element (12) having an infinitely rotatable activation part (13),
• wherein a movement path to be performed by the tool head is defined in the control program, which movement path comprises processing phases and rapid-speed phases of the tool head, which follow one another in terms of time,
• and wherein change-overs between the first and the second usage state of the rotary control element (12) are determined in the control program.
