摘要： A feeler device for geometrically controlling parts, capable of determining the position of a feeler member when it comes into contact with a part to be controlled. The feeler device includes a motorized contact rod movable in translation inside a housing and a microcontroller for controlling the movement of the rod. The contact rod is driven in translation by friction with an element linked to the rotary shaft of a motor, and the contact rod cooperates with a magnetic sensor in order to detect the position of same.

摘要： A shape measuring apparatus includes a probe head that changes its posture by rotational motion of a first drive axis and a second drive axis, and a coordinate measuring machine that three-dimensionally displaces a location of the probe head by three translation axes (a third drive axis, a fourth drive axis, and a fifth drive axis). The location of a measurement tip is given by coordinate values of the third to fifth drive axes, and the posture of a probe head is given by a first rotating angle α and a second rotating angle β. An intersection point between a first rotation axis and a second rotation axis is set as a rotation center Q. An interpolation point in each control period is calculated for each of the first to fifth drive axes.

摘要： A method is described for analysing probe data collected by a scanning probe carried by a machine tool. The probe data is collected as the machine tool moves or scans the scanning probe along a scan path relative to a workpiece. The method includes a step of identifying a property of the scan path used by the machine tool from a characteristic of the collected probe data. In this manner, the scan path can be identified from the probe data alone without having to receive any position data from the machine tool.

摘要： An articulating probe for use with a coordinate measuring machine comprises an attachment portion, a measuring portion, and at least one articulating joint. The attachment portion can be configured for attachment to a coordinate measuring machine. The measuring portion can be configured to contact an object to be measured by the coordinate measuring machine. The at least one articulating joint can be configured to allow rotation between the attachment portion and the measuring portion. Further, the articulating joint can comprise an angular sensor configured to measure an angle of the joint.

摘要： A recess or “pocket” is formed in at least one leg of a moving bridge assembly of a coordinate measuring machine, and in a particular embodiment in a primary leg of a moving bridge assembly, to permit a quill to move farther in the X direction to an end of a planar base surface of the coordinate measuring machine adjacent the leg without interfering with the leg. The recess formed in the leg of the moving bridge assembly permits coordinate measurements of a part whose width covers the full area of the planar surface of the base, without necessarily adding significant cost or increasing the footprint of the measurement system.

摘要： To inspect a positioning machine by a laser tracking interferometer that tracks a retroreflector using a laser beam, the positioning accuracy of the positioning machine is evaluated by comparing a distance Δdij,C with a distance Δdij,L measured by the laser tracking interferometer, the distance Δdij,C being acquired by orthogonal projection of the position vectors of measurement points pi and pj measured by the positioning machine to the straight line gk passing through the rotation center M of the laser tracking interferometer.
