Destructive web thickness measuring system of microdrills and method thereof

A destructive web thickness measuring system of microdrills for measuring a web thickness value of a microdrill, comprising:

• a computer device;
• a dual-axis motion platform module, coupled to the computer device, and used for holding the microdrill, wherein the computer device controls the dual-axis motion platform module to enable the microdrill to move;
• a drill grinding module, for grinding the microdrill to a sectional position to be inspected when the computer device controls the dual-axis motion platform module to move the microdrill to a grinding position;
• a positioning vision module, for capturing and outputting a first image to the computer device when the computer device controls the dual-axis motion platform module to move the microdrill to a first locating position, wherein the computer device performs a positioning procedure according to the first image to obtain a first distance between the microdrill and the drill grinding module, and the computer device controls the drill grinding module according to the first distance and the sectional position to be inspected, so that the drill grinding module grinds the microdrill to the sectional position to be inspected, the first locating position is in a first image capture range of the positioning vision module, and the microdrill does not contact with the drill grinding module;
• and
• a web thickness measuring vision module, for capturing and outputting a second image to the computer device when the computer device controls the dual-axis motion platform module to move the microdrill to an image measuring position, wherein the computer device performs an image computing procedure according to the second image to obtain the web thickness value of the microdrill at the sectional position to be inspected, and the image measuring position is in a second image capture range of the web thickness measuring vision module.
