Patent number: 11524340Abstract: A tool body includes a damping apparatus for damping vibrations in a machining tool having, besides the tool body, a member with at least one cutting edge to be secured to the tool body. The damping apparatus is arranged in an internal room of the tool body and includes a damper mass body with an axial bore and a central tube extending through the bore and which is rigidly secured to the damper mass body inside the through bore. A central tube is also at both ends thereof rigidly connected to a tool body fixed part and the central tube is made of a material with a spring property allowing the damper mass body to oscillate in the internal room perpendicularly to the longitudinal extension of the central tube.Type: GrantFiled: September 11, 2018Date of Patent: December 13, 2022Assignee: SANDVIK INTELLECTUAL PROPERTY ABInventors: Dan Ostling, Tormod Jensen

Patent number: 11285543Abstract: A cutting tool, a turning machine including the cutting tool, and an associated method are provided. The cutting tool includes a tool, a cutting head, a strain gauge, and an accelerometer. The cutting head is located at the tool bar and has a cutting edge. The strain gauge measures strain at the tool bar. The accelerometer measures acceleration at the tool bar or the cutting head. Deflection of the cutting edge is estimated based on output from the strain gauge and the accelerometer. In some embodiments, the accelerometer is arranged close to the cutting edge, while the strain gauge is arranged where the tool bar is susceptible to the largest strain. In some embodiments, low frequency vibrations of the cutting edge are estimated based on measured strain, high frequency vibrations are estimated based on measured acceleration, and medium frequency vibrations are estimated based on output from both sensor types.Type: GrantFiled: August 24, 2017Date of Patent: March 29, 2022Assignee: SANDVIK INTELLECTUAL PROPERTY ABInventors: Dan Ostling, Tormod Jensen, Mathias Tjomsland, Oddvar Standal, Ole Henrik Johansen, Arnt Erik Reinsbakk

Patent number: 10717133Abstract: A cutting tool, a turning machine including the cutting tool, and an associated method are provided. The cutting tool includes a tool bar extending along an axis, a cutting head located at the tool bar, and at least one sensor integrated with the tool bar or the cutting head. A rotational orientation of the cutting tool with respect to the axis is estimated based on output provided by the at least one sensor. In at least some embodiments, the at least one sensor includes accelerometers configured to measure acceleration in at least two directions.Type: GrantFiled: August 18, 2017Date of Patent: July 21, 2020Assignee: SANDVIK INTELLECTUAL PROPERTY ABInventors: Oddvar Standal, Mathias Tjomsland, Ole Henrik Johansen, Dan Ostling, Tormod Jensen

Publication number: 20100007892Abstract: A dome-shaped chemical sensing probe comprises an optical fiber or may be mounted on an optical fiber. The probe has a chemically sensitive measuring material which exhibits a change in volume and/or a change in refractive index in the presence of a given chemical. The change in volume and/or refractive index gives a change in an optical path length through the probe which can be measured interferometrically.Type: ApplicationFiled: September 15, 2009Publication date: January 14, 2010Applicant: Invivosense ASAInventors: Dag R. Hjelme, Arne Berg, Reinold Ellingsen, Berit Falch, Astrid Bjorkoy, Dan Ostling
