Non-destructive and optical measurement automation system for web thickness of microdrills and method thereof

摘要

A non-destructive and optical measurement automation system for web thickness of microdrills and method thereof can obtain the measuring data corresponding to a certain section to be measured of a microdrill by means of automated optical measurement. Specifically speaking, the said system and method measure the section to be measured via an optical measuring plane formed by a measuring light beam, and the included angle between the optical measuring plane and the central axis of the microdrill is practically consistent with the helix angle of the microdrill. The said system and method then analyze the measuring data via a computer device to obtain the outer diameter and the depths of helical flutes corresponding to the section to be measured. Finally, the said system and method calculate the web thickness of the said section to be measured according to the outer diameter and the depths of helical flutes.
