Publication number: 20200309509Abstract: A method for assessing the profile of a tool using a non-contact tool setting apparatus that includes a transmitter for emitting a light beam and a receiver for receiving the beam. The receiver generates a beam intensity signal describing the intensity of received light. The setting apparatus is mounted to a coordinate positioning apparatus that allows the tool to be moved relative to the setting apparatus. The method includes using the coordinate positioning apparatus to move the tool relative to the setting apparatus along a tool inspection path, the tool inspection path being selected so that the light beam is traced substantially along a periphery of the tool to be inspected. Beam intensity data is collected describing the beam intensity signal that is generated by the receiver as the tool inspection path is traversed and analysis of the collected beam intensity data is used to assess the tool profile.Type: ApplicationFiled: August 31, 2018Publication date: October 1, 2020Applicant: RENISHAW PLCInventors: William Ernest LEE, Paul MAXTED
