  • Device for the automatic assignment of the position of a machining tool to a work-piece
    Publication number: 20030219322
    Abstract: The invention relates to a device for the automatic assignment of the position of a rotating tool with respect to pre-machined toothing of a work-piece to be machined. According to the invention, the tool can be introduced in an arbitrary position between the tooth flanks. In a touch mode, the distance from the feed-in position to the tooth flanks can be determined by relative rotation of the work-piece to the tool and the desired target position of the tool can be calculated from this value.
