Abstract
In a method for operating a machine tool, a machine-specific flow resistance and a respective tool-specific flow resistance are ascertained for various tools. Tool-specific regulator parameters for regulating a pump of a coolant lubricant device are computed on the basis of the machine-specific flow resistance and the tool-specific flow resistance of the tool chucked in a tool spindle. Subsequently, the machine tool is operated using the tool-specific regulator parameters. In this way, a rapid and exact feed of coolant lubricant to the machining point of the respective chucked tool is enabled in a simple and flexible manner.
Claims17
A method for operating a machine tool, the method comprising the following steps:
- providing a machine tool comprising at least one tool spindle and a coolant lubricant device having a pump for supplying the at least one tool spindle with a coolant lubricant;
- chucking a tool in the at least one tool spindle;
- computing tool-specific regulator parameters for regulating the pump based on a machine-specific flow resistance for the coolant lubricant and a tool-specific flow resistance for the coolant lubricant;
- and
- operating the machine tool using the tool-specific regulator parameters, wherein the machine-specific flow resistance is ascertained by operating the machine tool without the tool.
A machine tool, comprising:
- at least one tool spindle;
- a coolant lubricant device having a pump for supplying the at least one tool spindle with a coolant lubricant;
- and
- a control device configured such that tool-specific regulator parameters for regulating the pump are computed based on a machine-specific flow resistance for the coolant lubricant and a tool-specific flow resistance for the coolant lubricant, wherein the machine-specific flow resistance is ascertained by operating the machine tool without the tool, the machine-specific flow resistance is stored in the control device, the tool-specific flow resistance is ascertained by operating the machine tool using the tool chucked in the at least one tool spindle, and the tool-specific flow resistance is stored in conjunction with an identification in a control device.
A manufacturing facility comprising:
- multiple machine tools and a central control device, each of the machine tools comprising at least one tool spindle, a coolant lubricant device and a control device, the coolant lubricant device having a pump for supplying the at least one tool spindle with a coolant lubricant, the control device being configured such that tool-specific regulator parameters for regulating the pump are computed based on a machine-specific flow resistance for the coolant lubricant and a tool-specific flow resistant for the coolant lubricant, wherein the machine-specific flow resistance is ascertained by operating the machine tool without the tool and the machine-specific flow resistance is stored in the control device, the tool-specific flow resistance is ascertained by operating the machine tool using the tool chucked in the at least one tool spindle, and the tool-specific flow resistance is stored in conjunction with an identification in a control device.
