Patent number: 10507560Abstract: A positioning apparatus for positioning a tactile or optical roughness sensor, a probe or some other measuring instrument with respect to a workpiece can be secured to a movement device of a coordinate measuring machine. The positioning apparatus has a drive that produces a relative movement between two parts of the positioning apparatus, and an inhibiting device, which inhibits the relative movement between the two parts. For this purpose, the inhibiting device has a first friction element and a second friction element each having unlubricated friction surfaces. The friction surfaces are pressed against one another with a normal force that is not variable during the operation of the positioning apparatus. A coefficient of sliding friction that is less than 0.15 acts between the friction surfaces in the case of dryness and without lubrication. Typically, the inhibiting device is arranged in a flexspline of a strain wave gearing.Type: GrantFiled: March 23, 2018Date of Patent: December 17, 2019Assignee: Carl Zeiss Industrielle Messtechnik GmbHInventors: Kurt Brenner, Christian Bayer, Dieter Kaufmann, Otto Steinecker, Philipp Mayinger, Tobias Held

Patent number: 10281579Abstract: A method for operating a confocal white light sensor on a coordinate measuring machine including a sensor carrier configured to couple a coordinate measurement sensor that is movable in a straight movement direction relative to a base of the coordinate measuring machine is provided. A confocal white light sensor is coupled to the sensor carrier and oriented in the straight movement direction toward a reference body. The sensor carrier and the reference body are moved relative to one another in the straight movement direction, and a measurement signal representing a distance between the confocal white light sensor and the reference body is generated at different movement positions. Information relating to a relationship between measurement signals of the confocal white light sensor and an actual distance of the white light sensor to a measurement object is obtained and a measurement value of the object distance is generated.Type: GrantFiled: March 15, 2018Date of Patent: May 7, 2019Assignee: Carl Zeiss Industrielle Messtechnik GmbHInventors: Rudolf Kern, Jochen Burger, Kurt Brenner

Patent number: 9261344Abstract: A probe head for a coordinate measuring machine has a coupling part having a retaining pin, on which a probe tool is detachably arranged. The probe tool has at least one stylus for touching a measurement object, and a rotary plate. The rotary plate is coupled to the coupling part by means of the retaining pin in one of a plurality of defined rotation angle positions. Moreover, the rotary plate has a latching mechanism including at least one adjustable latching element and a detector. The latching element has a latching position in which it fastens the rotary plate on the retaining pin, and it has a release position in which it releases the retaining pin. The detector generates a signal which is representative of at least one from the latching position and the release position.Type: GrantFiled: November 2, 2012Date of Patent: February 16, 2016Assignee: CARL ZEISS INDUSTRIELLE MESSTECHNIK GMBHInventors: Kurt Brenner, Walter Jenisch

Patent number: 9140532Abstract: A measuring head for a coordinate measuring machine for determining spatial coordinates on a measurement object has a coupling part for detachably receiving a measurement tool. The coupling part has a number of first bearing elements, a magnet and a retaining pin. The measurement tool has a disk with a number of second bearing elements, an anchoring plate and at least one adjustable locking element.

The first and second bearing elements, in the engaged state, define a defined position of the measurement tool on the coupling part. The at least one locking element secures the measurement tool to the retaining pin. The anchoring plate is detachably secured to the disk and the at least one locking element retains the anchoring plate on the retaining pin.Type: GrantFiled: October 30, 2013Date of Patent: September 22, 2015Assignee: CARL ZEISS INDUSTRIELLE MESSTECHNIK GMBHInventors: Kurt Brenner, Walter Jenisch, Tobias Woletz, Dieter Kaufmann

Patent number: 8701529Abstract: A method of grooving a work-piece of superalloy uses a grooving cutting insert at least partially covered with a Cubic Boron Nitride (CBN) layer and having one or more interior ducts formed therein which open out to the insert's rake face at one or more corresponding openings. One or more coolant fluid streams, conveyed via these interior ducts at a pressure of no less than 200 bars, are directed upwardly and outwardly toward an interaction area between a cutting edge of the cutting insert and the work-piece, to thereby limit lengths of work-piece chips created during the grooving operation. The openings of the cutting insert's interior ducts may be located between 0.5-3.0 mm from the insert's cutting edge.Type: GrantFiled: January 11, 2010Date of Patent: April 22, 2014Assignee: Iscar, Ltd.Inventors: Patrick Deschenaux, Kurt Brenner

Patent number: 7284337Abstract: A probe head for a coordinate measuring machine has a stylus resiliently suspended in a housing. A sensor arrangement serves for detecting deflections of the stylus relative to the housing. The sensor arrangement comprises at least one Hall sensor having a magnet and a Hall element arranged in a vicinity to each other. When the stylus is deflected, the magnet is laterally passed by the Hall element in a direction defined from the North Pole to the South Pole of the magnet or vice versa. A Hall voltage of changing polarity can be tapped at the Hall element then. A preferably linear range around the polarity change is processed in order to determine the deflection of the stylus.Type: GrantFiled: April 14, 2005Date of Patent: October 23, 2007Assignee: Carl Zeiss Industrielle Messtechnik GmbHInventors: Kurt Brenner, Walter Jenisch, Horst Stacklies, Roland Roth
