A three-dimensional measuring device, comprising an arm having a free end provided with an interface body carrying a measuring member and a handle enabling an operator to point the measuring member at a zone of the object that is to be measured, the measuring device being characterized in that the handle is tubular in shape with a grippable outside surface and an inside surface that defines a housing in which there is engaged a reinforcing portion of a fastener base, which portion has an end portion that projects from the handle and that is fastened to the interface body.

Measuring arm with multifunctional end

A three-dimensional measuring device, comprising an arm having a free end provided with an interface body and a handle enabling an operator to point the measuring member at a zone of the object that is to be measured. The handle is secured to a fastener base having an end portion that includes a slideway extending transversely relative to the longitudinal direction of the handle in order to co-operate with a slideway of the interface body, the interface body and the end portion of the fastener support having both complementary abutment means so as to define a mutual engagement position of the slideways and also complementary locking means that oppose disengagement of the slideways, the complementary locking means including a control lever that is hinged to the end portion of the fastener base between an activation position for activating the locking means and an inactivation position for inactivating the locking means.

A three-dimensional measuring device, comprising an arm having a free end provided with an interface body carrying a measuring member and a grip member enabling an operator to point the measuring member at a zone of the object that is to be measured. The interface body has a front face in which at least one electrical connector is accessible and from which there extends a projecting tubular coupling part for coupling to the measuring member, an annular grippable body being engaged on the tubular coupling part and extending over the front surface and the electrical connector, a retaining element being mounted on the grippable body to co-operate with the tubular coupling part in order to hold the grippable body pressed against the front face of the interface body.

A three-dimensional measuring device, comprising an arm having a free end provided with an interface body carrying a measuring member and a grip member enabling an operator to point the measuring member at a zone of the object that is to be measured. The measuring member includes a male cylindrical portion having a portion engaged in a tubular coupling part secured to the interface body, the tubular coupling part is provided with a coupling locking mechanism comprising a tab mounted on a pin provided with a first annular sealing gasket bearing against a surface of the tubular coupling part, and a second annular sealing gasket is mounted between the tubular coupling part and the male cylindrical portion to be deformed between them when the male cylindrical portion is mounted in the tubular coupling part secured to the interface body.

A three-dimensional measuring device comprising an arm having a free end provided with an interface body that includes a front face that has projecting therefrom a tubular coupling part for coupling to a first measuring member for measuring by contact and that is arranged to form a fastener plate for fastening either to a first grip member or else to a second measuring member, and the interface body also includes a side surface arranged to form a second fastener plate for fastening to a second grip member.

A three-dimensional measuring device, comprising an arm having a free end provided with an interface body carrying a measuring member and a grip member enabling an operator to point the measuring member at a zone of the object that is to be measured. The measuring member includes a connector to be electrically connected to a corresponding connector of the interface body by a fastener mechanism that is controllable by a lever and that is arranged in such a manner that the lever controls the fastener mechanism to occupy selectively a snap-fastening state in which the measuring member is held on the interface body while the connectors are disengaged from each other, a locking state in which the measuring member is fastened to the interface body and the connectors are engaged with each other, or a release state in which the measuring member can be separated from the interface body.

A method of operating an articulated arm CMM is provided. One or more coordinates on an object can be measured with the articulated arm CMM. At least one of the encoders can then be at least partially powered-off. The encoder can then be powered on and one or more coordinates on the same object can be measured without recalibrating the encoder.

CMM with improved sensors

A method of operating an articulated arm CMM is provided. Instructions for the CMM can be inputted to the CMM arm by an action chosen from the group consisting of placing the arm in a predefined position and moving the arm in a predefined manner.

Systems and methods for control and calibration of a CMM

Method for measuring a part using an articulated measurement arm having a measurement head provided with a pointing member and at least one joint fitted with at least one rotary encoder, comprising focusing on a first measurement point on the part, the measurement arm adopting a first measurement position, moving the measurement arm to a second measurement position to focus on a second measurement point of the part in order to capture a geometric feature of the part on the basis of the measurement points, and determining a degree of precision of the capture of the geometric feature undertaken as a function of the first and second positions of the measurement arm.
