Patent number: 7256898Abstract: To determine the position of rotationally drivable tools in machine tools, the moment of separation of the tool to be measured and a measuring beam, for example a laser beam of a light barrier, is used. The tool to be measured is first positioned in such a manner that the measuring beam is interrupted, and is then moved to a measuring position in which the moment of separation of the tool and the measuring beam occurs, and the measuring beam is no longer interrupted by the tool during at least one complete revolution. The moment of separation is used to determine the position of the tool.Type: GrantFiled: February 19, 2004Date of Patent: August 14, 2007Assignee: Blum-Novotest GmbHInventors: Heribert Bucher, Wolfgang Reiser

Patent number: 6597464Abstract: The testing of a cutting-edge geometry of a tool takes place during time intervals that comprise time instants at which it is to be expected that a region, to be tested, of the tool enters a measuring beam. At time instants at which the tool does not enter the measuring beam, no measurements are performed, which increases the reliability of the test and avoids spurious measurements. For this purpose, a measuring system is used that preferably comprises programmable units in order to use the invention flexibly for various machine tools and tools without changing the construction of the measuring system.Type: GrantFiled: April 17, 2002Date of Patent: July 22, 2003Assignee: Blum-Novotest GmbHInventors: Heribert Bucher, Bruno Riedter

Patent number: 6141106Abstract: The measuring instrument comprises a retaining fixture adapted to hold an object to be measured in a center plane of the measuring instrument, defined by a guide, in such a position that a dimension of interest will extend parallel to the guide. A carriage supporting a transmitter and a receiver, respectively, at either side of the center plane for an energy beam focused on the center plane is movable along the guide. A distance measuring device provided to measure movements of the carriage along the guide comprises a rule member which is disposed in the center plane. The dimension of interest is determined based on positions of the carriage at which the energy beam, first received by the receiver, is interrupted by the object to be measured and then again received.Type: GrantFiled: April 1, 1999Date of Patent: October 31, 2000Assignee: Blum-Novotest GmbHInventor: Gunther Blum
