Method for Determination of an Effective Machine Use of a Machine Tool as well as Machine Tool Configured Therefore

A machine tool (10) comprising:

• multiple machine axes (16) that are configured for movement of a workpiece (13) and/or a tool (12),
• a rotary drive (11) configured for rotating the workpiece (13) or the tool (12), and
• a control unit (18), wherein the control unit (18) is configured to execute a method for determination of an effective machine use of the machine tool (10) that comprises the following steps:
• determining a use duration characteristic parameter (T) that characterizes a duration during which the workpiece (13) is machined by the tool (12),
• determining an output power characteristic parameter (L) that characterizes a power applied for machining the workpiece (13) during the use duration,
• determining a machine use characteristic parameter (M) that characterizes the effective machine use by using the use duration characteristic parameter (T) and the output power characteristic parameter (L), and
• providing the machine use characteristic parameter (M) in the control unit (18) of the machine tool (10) for transmission to an external unit (20).

A method for determination of a machine tool rent fee including a use-dependent fee based on an effective machine use of a machine tool (10) comprising multiple machine axes (16) that are configured for moving a workpiece (13) and/or a tool (12), a rotary drive (11) configured for rotating the workpiece (13) or the tool (12) and a control unit (18), wherein the method comprises the following steps:

• determining a use duration characteristic parameter (T) that characterizes a duration during which the workpiece (13) is machined by the tool (12) by the control unit (18),
• determining an output power characteristic parameter (L) that characterizes a power applied for machining of the workpiece (13) by the control unit (18),
• determining a machine use characteristic parameter (M) that characterizes the effective machine use by using the use duration characteristic parameter (T) and the output power characteristic parameter (L) in the control unit (18) of the machine tool (10) and providing the machine use characteristic parameter (M) in the control unit (18) of the machine tool (10) for transmission to an external unit (20),
• calculating the use-dependent fee (FU) based on the machine use characteristic parameter.
