オートフォーカス機構を組み込んだ光計測による非接触工具損傷モニタリング装置の開発

抄録

Noncontact monitoring equipment for detecting tool failures by optical measurement has been developed for applications to machining centers, turning centers, etc. The equipment consists of : (1) An auto-focusing device for an ITV camera to focus on the failed portions of a tool. (2) A four halogen lamp system for contrasting the failed portions against the normal region. (3) An image processing procedure for extracting failed portions from a composite tool image obtained by lighting the tool from three different axes. (4)An accurate calculating method of quantifying the failures.
