1. How to enter measurement point coordinates

During measurement, the probe performs three orthogonal translations relative to the machine frame, the displacement values of which are measured by rulers. From a machine origin, defined for example by the origins of each of the measuring rulers, the three displacements are the coordinates of a point P on the measuring machine slide (figure 1 ).

To measure the shape of all or part of the surface of an object placed on the machine's marble, a sphere with center ω, located at the tip of the stylus, successively touches different selected points M _i of the object's surface. Not all points on the surface to be characterized are accessible with a single stylus orientation. It is therefore necessary to adapt this orientation so that the stylus...
