Abstract
A benchmark device for a plane face comprises at least three benchmark elements which together define a reference plane parallel to said plane face, together with a system of rectangular axes enabling any point of said plane face to be located.
Claims11
A benchmark device for a plane face, wherein the device includes three benchmark elements, which are carried by said plane face and which are such that:
- the first benchmark element includes a rectangular trihedron with two facets that are orthogonal to said plane face and a third facet of said trihedron being parallel to said plane face such that one of the edges of said trihedron is perpendicular to said plane face and the other two edges of said trihedron are parallel to said plane face;
- the second benchmark element includes a rectangular dihedron whose facets are respectively orthogonal and parallel to said plane face, such that the edge of said dihedron is parallel to said plane face, and
- the third benchmark element includes a facet parallel to said plane face;
- and
- wherein said benchmark elements are disposed on said plane face in such a manner that:
- they are not in alignment;
- the facets of said three benchmark elements that are parallel to said plane face are coplanar;
- and
- said edge of said second benchmark element is colinear with one of the two edges of said first benchmark element that are parallel to said plane face.

A system enabling a member to be brought to a precise location of an object linked to a plane face, said plane face occupying a fixed position that is different from but adjacent to a nominal position, wherein:
- said member is carried by a moving support capable of moving in translation along three orthogonal axes and capable of rotating about two perpendicular axes, said movable support being movable with respect to said three orthogonal axes;
- said plane face being positioned with respect to said three orthogonal axes;
- said movable support accordingly being movable with said respect to said plane face;
- said moving support carries a distance detector;
- said system includes three benchmark elements which are carried by said plane face and which are such that:
- the first benchmark element includes a rectangular trihedron with two facets that are orthogonal to said plane face and a third facet of said trihedron being parallel to said plane face such that one of the edges of said trihedron is perpendicular to said plane face and the other two edges of said trihedron are parallel to said plane face;
- the second benchmark element includes a rectangular dihedron whose facets are respectively orthogonal and parallel to said plane face, such that the edge of said dihedron is parallel to said plane face, and
- the third benchmark element includes a facet parallel to said plane face;
- and
- said benchmark elements are disposed on said plane face in such a manner that;
- they are not in alignment;
- the facets of said three benchmark elements that are parallel to said plane face are coplanar;
- and
- said edge of said second benchmark element is collinear with one of the two edges of said first benchmark element that are parallel to said plane face.
