Numerical control system

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 tool or the work, the images of the tool or the work being captured by an imaging device;
• and
• a numerical controller that controls the machine and controls the image processing device on a 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 image processing from the image processing device to operation control information of a format that can be recognized by the program analysis unit.
