Title
(EN) NON-CONTACT TOOL SETTING APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ DE RÉGLAGE D'OUTIL SANS CONTACT
Abstract
(EN)
A method and an apparatus are described for assessing the profile of a tool (50; 80; 170) using a non-contact tool setting apparatus (150) that comprises a transmitter (10) for emitting a light beam (12; 152) and a receiver (14) for receiving the light beam. The receiver (14) generates a beam intensity signal describing the intensity of received light. The non-contact tool setting apparatus (150) is mounted to a coordinate positioning apparatus, such as a machine tool, that allows the tool (50; 80; 170) to be moved relative to the non-contact tool setting apparatus (150). The method comprises using the coordinate positioning apparatus to move the tool (50; 80; 170) relative to the non-contact tool setting apparatus (150) along a tool inspection path (56;88), the tool inspection path being selected so that the light beam is traced substantially along a periphery of the tool (50; 80; 170) to be inspected. Beam intensity data is collected describing the beam intensity signal that is generated by the receiver (14) as the tool inspection path (56;88) is traversed and analysis of the collected beam intensity data is used to assess the tool profile.

L'invention concerne un procédé et un appareil pour évaluer le profil d'un outil (50 ; 80 ; 170) à l'aide d'un appareil de réglage d'outil sans contact (150) qui comprend un émetteur (10) pour émettre un faisceau de lumière (12 ; 152) et un récepteur (14) pour recevoir le faisceau de lumière. Le récepteur (14) génère un signal d'intensité de faisceau décrivant l'intensité de la lumière reçue. L'appareil de réglage d'outil sans contact (150) est monté sur un appareil de positionnement de coordonnées, tel qu'une machine-outil, qui permet à l'outil (50 ; 80 ; 170) d'être déplacé par rapport à l'appareil de réglage d'outil sans contact (150). Le procédé comprend l'utilisation de l'appareil de positionnement de coordonnées pour déplacer l'outil (50 ; 80 ; 170) par rapport à l'appareil de réglage d'outil sans contact (150) le long d'un trajet d'inspection d'outil (56 ; 88), le trajet d'inspection d'outil étant sélectionné de telle sorte que le faisceau de lumière est tracé sensiblement le long d'une périphérie de l'outil (50 ; 80 ; 170) à inspecter. On collecte des données d'intensité de faisceau décrivant le signal d'intensité de faisceau qui est généré par le récepteur (14) lorsque le trajet d'inspection d'outil (56 ; 88) est traversé et on utilise l'analyse des données d'intensité de faisceau collectées pour évaluer le profil d'outil.
