ABSTRACT:
A device forming a sight-vane for a three-dimensional measuring machine. It includes a cylinder-shaped body (1), a thin part (5), and a tail (6). The part (5) and the tail (6) are provided with slots enabling the expansion or the withdrawal of the tail (6) in relation to the nominal diameter thereof. A contact face (2) is calibrated in relation to a bearing face (3). A cylinder (4) and the contact face (2) are calibrated and intended for the palpation. The exterior of the tail (6) is calibrated, the interior is provided with a conical (11) bore and the end thereof is provided with a wedge-shaped chamfer (13). The contact face (2) is provided with a countersink (9) and a threading (8) suitable for receiving an expansion screw (10) at the conical end. The device is useful as a palpation point for a measuring machine.
