Patent number: 8535208Abstract: Tool rack for tools of a coordinate measuring machine, wherein the guiding and retaining surfaces of the tool rack are arranged on two planes offset vertically so as to cause the tool to tilt when it is unhooked. The inventive arrangement allows the mechanical efforts during uncoupling to be reduced appreciably. This reduction is due to the tool tilting and to the residual magnetic force being divided between three retaining point, with a positive effect on the coupling precision and on the tool positioning in the tool rack.Type: GrantFiled: June 5, 2007Date of Patent: September 17, 2013Assignee: Hexagon Metrology ABInventors: Pascal Jordil, Benjamin Vullioud

Patent number: 8082674Abstract: A probe, connectable to a machine tool, has an electric generator and a driving element. The electric generator supplies an electric or electronic circuit with electric power, and the driving element is capable of relative rotation with respect to the stator of the electric generator. The driving element is not connected to any external energy source and can be set in rotation simply by activating the rotary axis of the machine tool. The driving element is either rotatably mounted on the probe itself or fixed on the reference table of the machine tool. The probe requires no additional connections to the machine tool on which it is mounted, besides the connection to the rotary spindle, which can be realized with a conventional tool-holder with a standardized tapered shank. The probe is fully compatible with standard probes and can be mounted and used with standard tool-holders without any adaptation.Type: GrantFiled: April 21, 2009Date of Patent: December 27, 2011Assignee: Hexagon Metrology ABInventors: Pascal Jordil, François Gabella

Patent number: 7779553Abstract: A method for scanning a surface of a workpiece using a scanning probe 2 mounted on a support 3 on a coordinate measuring machine 4. The support contains drive means 5, 7 for actuating the movement of the scanning probe 2 relatively to the support 3. The method further involves detecting means 9 to measure a contact force F applied between the tip 10 of the probe and the surface 1, control means 13 coupled to the drive means, and memory means 14 for storing theoretical profiles 19 and coordinates 20 of the surface. This method is characterized by the fact that the control means 13 adjust the actuation of the drive means 5, 7 along a scanning path 18 in order to maintain the contact force 11 within the defined range of values 15 during the whole scanning operation along the scanning path 18.Type: GrantFiled: March 17, 2008Date of Patent: August 24, 2010Assignee: Hexagon Metrology ABInventors: Pascal Jordil, Bo Pettersson, Siercks Knut

Publication number: 20090265946Abstract: A probe, connectable to a machine tool, having an electric generator (16), supplying an electric or electronic circuit (22) with electric power, and a driving element (28), capable of relative rotation with respect to the stator of the electric generator. The rotation axis of the driving element is preferably a symmetry axis of the probe itself. The driving element is not connected to any external energy source, and can be set in rotation simply by activating the rotary axis of the machine tool. Advantageously, the driving element of the present invention is not directly connected with any mobile element of the machine tool, but is either rotatably mounted on the probe itself, or fixed on the reference table of the machine tool. Importantly, the inventive probe requires no additional connections to the machine tool on which it is mounted, besides the connection to the rotary spindle, which can be realized with a conventional tool-holder with a standardised tapered shank.Type: ApplicationFiled: April 21, 2009Publication date: October 29, 2009Applicant: HEXAGON METROLOGY ABInventors: Pascal Jordil, Francois Gabella

Patent number: 7503125Abstract: A measuring method and system involving a measuring coordinate probe, which can be moved precisely, by appropriate actuators, with respect to a positioning platform (60) on which the probe is mounted; and whose position relative capable to said positioning platform (60) can be measured, by suitable encoders (780). The invention can be carried out with probes, actuators and encoders of different nature. The actuators (730) preferably allow the motion of the probe according to two or more independent degrees of freedom, so that the probe itself can be moved in a plane, or in a three-dimensional region of space, and its orientation can be chosen, within some suitable limits. The method and system of the invention provide very exact local measurement, even if the platform (60) does not deliver the very best precision.Type: GrantFiled: April 29, 2008Date of Patent: March 17, 2009Assignee: Hexagon Metrology ABInventors: Pascal Jordil, Bo Pettersson
