摘要： In the machine tool (10) pertaining to the present invention, the contour lines (51) of a tool (20) are displayed on a display screen (S). When an operator measuring the dimensions traces a contour line (51) on the display screen (S) of a touch panel (45) with a finger, it is possible to automatically identify, on the display screen (S), the site to be measured (i.e., the contour line (51)) on the tool (20). In this way, an operator can measure the dimensions of the tool (20) in an extremely simple manner. Additionally, it is possible to automatically measure the tool diameter or the blade position of the tool (20) as the operator designates a specific position on the contour line (51) of the tool (20). Thus, with such a method for measuring the dimensions of the tool (20), it is possible to easily identify an unexpected site to be measured on a tool having complex contour lines, such as a multi-stage tool.

摘要： In the machine tool (10) pertaining to the present invention, an imaging device (33) takes an image of a tool (20) being moved in the feeding direction. Contour lines (51) are identified by means of the plurality of sets of image data generated from imaging. The movement trajectory (52) and the central axis (53) of the tool (20) are identified on the basis of the contour lines (51). When the movement trajectory (52) and the central axis (53) are offset, said offset can be used to correct the positioning of the tool (20) with the machine tool (10). As a result, the processing accuracy of a workpiece improves. Moreover, when the dimensions of a tool (20) that has a tilted posture are measured, it is possible to determine the actual tool diameter or the actual blade position in the tilted posture. The aforementioned blade position and tool diameter can be used to correct the positioning of the machine tool (10). Thus, the processing accuracy of the workpiece improves even more.

摘要： Provided are a method for measuring tool dimensions and a measurement device, whereby if a machine tool (10) cannot fit the overall outline of a tool (20) inside the field of vision (V) for an image from an imaging device (33), the field of vision (V) of the imaging device (33) is moved by relatively moving the imaging device (33) and the tool (20). In addition, the imaging device (33) can follow the outline (54) of the tool (20) by moving the field of vision (V), because the movement direction (53) for the field of vision (V) is determined on the basis of the partial outline (51) specified based on image data. In this way, even when measuring dimensions for a tool (20) with a larger diameter than the field of vision (V) of the imaging device (33), a partial outline (51) of a desired range, for example, is specified. An outline of a desired range for the tool (20) is extracted if a plurality of specified partial outlines (51) are combined. Measurement of the dimensions of the tool (20) is possible by using such outlines.
摘要翻译：提供了一种用于测量工具尺寸的方法和测量装置，其中如果机床（10）不能将来自成像装置（33）的图像的视野范围（V）内的工具（20）的总体轮廓拟合，通过相对移动成像装置（33）和工具（20）来移动成像装置（33）的视野（V）。此外，由于用于视野（V）的移动方向（53）是通过视场（V）的移动方向（53）确定的，所以通过移动视场（V），成像装置（33）可以跟随工具（20）的轮廓（54）基于图像数据指定的部分轮廓（51）的基础。以这种方式，即使当测量具有比成像装置（33）的视野（V）更大的直径的工具（20）的尺寸时，指定例如期望范围的局部轮廓（51）。如果组合多个指定的部分轮廓（51），则提取工具（20）的期望范围的轮廓。可以通过使用这样的轮廓来测量工具（20）的尺寸。

摘要： A wear amount of a working tool T during the machining of a workpiece is estimated during the machining, and a positional command generated in accordance with a predetermined machining program is sequentially corrected during the machining based on the estimated wear amount of the working tool T. The workpiece W is machined in accordance with the corrected positional command. Also, the wear amount of the working tool T upon the interruption of the machining operation is calculated, and the positional command generated in accordance with the predetermined machining program is corrected based on the calculated wear amount of the working tool so that a tool edge position of the working tool T upon the interruption of the machining operation coincides with the tool edge position of the working tool T upon the restart of the machining operation when the machining operation is restarted at a position where the machining operation has been interrupted. The workpiece is machined in accordance with the corrected positional command.
