Patent number: 8804104Abstract: A first thread feature is measured by detecting with an optical sensor 2 light that reaches from a light source 21 located on the opposite side of a pipe axis and runs substantially in parallel to thread grooves A4. A contact probe 31 of a contact sensor 3 is contacted with a thread flank surface A8 to detect the space coordinates of the contact probe 31 at the time of contact, so that a second thread feature is measured. The first and second thread features thus detected are combined with each other by a processor 4, and thread features of the thread provided as a measurement object are thereby calculated.Type: GrantFiled: March 26, 2009Date of Patent: August 12, 2014Assignees: Nippon Steel & Sumitomo Metal Corporation, Carl Mahr Holding GmbHInventors: Tatsuro Honda, Mutsumi Tanida, Seiji Hiraoka, Yasuhisa Kasa, Konrad Friedrich, Erhard Gruener
