Abstract

A numerical control system includes an image processing device that performs image processing on images captured by an imaging device and a numerical controller. The numerical controller includes a program analysis unit and a storage unit that stores operation control information of the machine, the imaging device, and the image processing device in a format that can be read and written by the program analysis unit. The numerical control system includes a conversion unit that converts commands or the operation control information stored in the storage unit to image processing input items which are setting values of a format that can be recognized by the imaging device and the image processing device and converts image processing output items which are the results of the image processing from the image processing device to operation control information of a format that can be recognized by the program analysis unit.

Claims

1. A numerical control system that controls a machine that performs predetermined processing on a work, comprising:

an image processing device that performs image processing on images of a machine or a work captured by an imaging device; and

a numerical controller that controls the machine and controls the image processing device on the basis of a program,

wherein the numerical controller or the image processing device controls the imaging device,

wherein the numerical controller includes;

a program analysis unit that analyzes the program; and

an operation control information storage unit that stores operation control information necessary when controlling operations of the machine, the imaging device, and the image processing device in a format that can be read and written by the program analysis unit, and

wherein the numerical control system includes;

an image processing input/output item-to-operation control information conversion unit that converts commands that the program analysis unit reads from the program or the operation control information stored in the operation control information storage unit to image processing input items which are setting values of a format that can be recognized by the imaging device and the image processing device and converts image processing output items which are results of the image processing from the image processing device to operation control information of a format that can be recognized by the program analysis unit.

2. The numerical control system according to claim 1, wherein the operation control information storage unit is macro variables that can be read and written by the program analysis unit.

3. The numerical control system according to claim 1, wherein the image processing input/output item-to-operation control information conversion unit is disposed in the numerical controller.

4. The numerical control system according to claim 1, wherein the image processing input/output item-to-operation control information conversion unit is disposed in the image processing device.
