1. A tool wear monitoring device configured to input a plurality of pieces of image data captured with a microscope camera while changing an angle, and to monitor tool wear of a tool, the device comprising:
a data analysis unit configured to analyze the plurality of pieces of image data,
wherein the data analysis unit,
binarizes the plurality of pieces of image data captured while changing the angle,
extracts data in which a worn region has a maximum area among the plurality of pieces of image data,
analyzes an amount of the tool wear of the tool from the extracted data with the maximum area, and
controls movement and operation of the tool based on the amount of the tool wear.
