ABSTRACT:
A bidimensional tracer for machine tools or measuring machines is described. Said tracer comprises a body for the connection to the machine, an end arranged to come into contact with a surface, and two detector elements apt to emit signals of detection of the movements of the said end, along two orthogonal directions, produced by the contact with the said surface.
The main characteristic of the tracer is that said detector elements simultaneously detect the said movements along the said two directions, the said two detector elements comprising each a portion stationary relative to the said connection body and a portion movable as a function of the movements of the said end.
