Embodiment Construction

[0058] figure 1 A schematic side view is shown for the dummy sensor, which is generally designated with reference number 2 . This sensor is used to determine the machine tool 6 (in figure 1 The state of the tool holder 4, such as the spindle, which is only partially shown in . In addition to the tool holder 4 , the machine tool 6 includes a tool 8 with which a workpiece 10 can be machined by running a machine program stored in a control unit 12 . Furthermore, the machine tool 6 comprises at least one sensor device 16 , by means of which a real time-dependent total energy consumption can be detected by the virtual sensor 2 and can be calculated by means of the time-dependent virtual total energy consumption.

[0059] figure 2 A schematic flowchart is shown. in reference to figure 1 In the case of the components of the machine tool 6 shown in , the method for operating the virtual sensor 2 for determining the state of the tool holder 4 of the machine tool 6 is described be...

Abstract

The invention relates to a method for operating a virtual sensor (2) for determining the state of a tool holder (4) of a machine tool (6); for example, a spindle of the machine tool (6), comprising atleast one tool holder (4) and at least one tool (8) that can be fastened or fastened to the tool holder (4), by means of which a workpiece (10) can be machined by the operation of a machine program;the machine tool has at least one control unit (12) comprising at least one sensor device (16).

Description

technical field [0001] The invention relates to a method for operating a virtual sensor for determining a state of a tool holder of a machine tool, a virtual sensor for determining the state of a tool holder, and a machine tool. Background technique [0002] In the case of working with a machine tool, workpieces (also called semi-finished products) are cut by the tools of the machine tool. Here, the tool is clamped in a tool holder of the machine tool, for example a spindle. [0003] Radial forces (forces perpendicular to the axis of rotation of the tool holder) acting on the tool holder, for example on the spindle, depend on a large number of parameters in the case of machining workpieces. These constraints on the good compatibility with the machine tool are the main criteria in setting up the machine program for machining workpieces. Permanent or repeated exceeding of established limits for these radial forces can lead to damage or destruction of the tool holder. [000...
