Abstract
An improved destructive and visual measurement automation system and a method for measuring a web thickness of a microdrill are provided. When a dual-axis motion platform module moves the microdrill to a first position, a reflection module reflects a first image in a first direction toward a second direction. A vision module receives the reflected first image in the second direction and outputs the received first image to a computer. According to the first image, the computer performs a positioning procedure and a grinding procedure to drive a drill grinding module to grind the microdrill to a sectional position to be measured of the microdrill. When the microdrill is moved to a second position, the vision module outputs a second image to the computer. According to the second image, the computer performs an image computing procedure to obtain the web thickness at the sectional position to be measured.
