Problems solved by technology

[0002] In a machine tool that rotates a tool or workpiece mounted on a rotary axis and moves the tool and workpiece relative to each other, damage to the tool causes a machining defect that prevents the workpiece from being machined into the desired size and shape.
In addition, even when the workpiece cannot be removed due to damage to the tool, the feed axis continues to move, resulting in the same situation as the collision between the tool and the workpiece, and not only the tool and the workpiece, but also the machine tool is damaged.

Embodiment Construction

[0042] Embodiments of the present invention will be described below with reference to the drawings.

[0043] figure 2 It is a unit configuration diagram showing an example of a machine tool. A spindle housing 1 of a machine tool is provided with a spindle 2 as a rotating shaft rotatable by a spindle motor, and a tool 3 such as a drill and an end mill is attached to an end of the spindle 2 . A workbench 5 is provided on the bed base 4, and the workpiece 6 is fixed on the workbench 5. The tool 3 and the workbench 5 are relatively moved in the direction of the X-axis, Y-axis, and Z-axis perpendicular to each other through the feed axis mechanism, thereby The machining of the workpiece 6 is performed.

[0044] 10 denotes an NC device that controls the machine tool, and the NC device 10 operates the machine tool according to a program to process the workpiece 6, and also functions as an information acquisition device of the present invention.

[0045] In the NC device 10, the p...

Abstract

The invention provides an information acquisition device of a machine tool that can preferably acquire machine information required for detailed process diagnostics and machine diagnostics. An NC device (10) has a machine information acquisition unit (13), a machine information clipping unit (18) correspondingly outputting time-series data and event data of machine information together, and a monitor. The machine information acquisition unit (13) includes a time series information recording unit (13A) acquiring machine information such as a main spindle load, loads of the respective feed axes, command values of the main spindle and the feed axes, or similar information from the machine operation instruction unit (14) at every any time, and an event information recording unit (13B) acquiring event information such as a program name, a tool number, and an override value through the operator's operation, or similar information from the machine operation instruction unit (14) at a time of change together with the change time.

Description

technical field [0001] The present invention relates to an information acquisition device for acquiring and recording machine tool information in a machine tool that performs machining while rotating a tool or a workpiece. Background technique [0002] In a machine tool that rotates a tool or a workpiece attached to a rotary shaft and moves the tool and the workpiece relative to each other, damage to the tool causes a machining defect that prevents the workpiece from being machined into a desired size and shape. In addition, even when the workpiece cannot be removed due to the damage of the tool, the feed axis continues to move, causing the same situation as the tool and the workpiece collide, and not only the tool and the workpiece, but also the machine tool is damaged. Therefore, the following measures are usually taken: monitoring the load of the spindle motor, which is considered to be the most representative of the processing state, and stopping the feed axis. A known ...
