Embodiment approach 1

[0025] figure 1 It is a figure which shows the structure of the information processing apparatus 1 concerning Embodiment 1 of this invention. The information processing device 1 performs a process of specifying a machining defect occurring in an object to be machined with a machining tool. Specifically, the information processing device 1 can process the object using the machining program 2 for changing the relative position of the machining tool and the object to be processed and the image data 24 obtained by photographing the object to be processed. The processing defective part of the object and the part in the processing program in which the operation for processing the processing defective part is described are identified. The object to be processed is also referred to as a workpiece.

[0026] The information processing device 1 has a program command reading unit 3 , a program feature quantity calculation unit 4 , an image reading unit 5 , an image feature quantity calc...

Embodiment approach 2

[0040] Figure 8 It is a figure which shows the structure of the information processing apparatus 10 concerning Embodiment 2 of this invention. In addition, the same reference numerals are assigned to the same constituent elements as those of the information processing device 1 according to Embodiment 1, and detailed description thereof will be omitted.

[0041] The information processing device 10 has a program command reading unit 3, a program feature quantity calculation unit 4, an interpolation unit 11, a motor control unit 12, a control data feature quantity calculation unit 15, an image reading unit 5, an image feature quantity calculation unit 6, A comparison unit 8 , a processing defect determination unit 13 , a cause determination unit 14 , and a display unit 9 .

[0042] The program command reading unit 3 inputs the read machining program 2 to the interpolation unit 11 and the program feature quantity calculation unit 4 . The interpolation unit 11 interpolates the ...

Embodiment approach 3

[0050] Figure 11 It is a figure which shows the structure of the information processing apparatus 100 concerning Embodiment 3 of this invention. The information processing device 100 further includes an image position calculation unit 7 in addition to the configuration of the information processing device 10 according to the second embodiment.

[0051] The image position calculation unit 7 obtains the installation position of the camera, the rotation angle of the table on which the object to be processed is fixed or the rotation angle of the machining tool, and the focal length at the time of image capture from the camera that captured the image data 24 for processing the image data 24. Information to determine the position of an object. The image position calculation unit 7 calculates the position of the entire object to be processed captured by the image data 24 based on the acquired information.

Abstract

An information processing device (1) is characterized by comprising a machining defect identifying unit (13) that identifies, on the basis of an image feature value (40) calculated from image data capturing a workpiece after machining, a machining defect in the workpiece and that identifies, on the basis of a program feature value (41) calculated from a machining program (2) for machining a workpiece and the image feature value (40), the section of the machining program (2) where the operation for machining the machining defect is described.

Description

technical field [0001] The present invention relates to an information processing device and a method for identifying a processing defect of an object to be processed. Background technique [0002] The numerical control device reads and executes the numerical control machining program that describes the movement instructions used to move the machining object or the machining tool along a preset path, so that the relative position of the machining object and the machining tool changes, and the machining object is processed. processing. In the above processing, processing defects may occur in the object to be processed. Machining failure is caused by, for example, an abnormality in the NC machining program or control data that causes the machining tool to deviate from the desired position with respect to the object to be processed, or is caused by a vibration called chatter between the machining tool and the object to be processed. produced by vibration. Machining defects d...
