A plant is made up of a plurality of automatic stations for the performance of
an assembly process of body parts or the like with there being in the stations
automatic support and blocking means for the parts to be assembled and automatic
assembly means for the parts supported and blocked and comprising in the stations
measurement sensors in established measurement points for measurement of geometrical
magnitudes of the parts in assembly with the measurement data taken by the sensors
being received by a processing unit which takes any deformations of the parts in
the various stations and goes back from the detected deformations to the causes
thereof in the asembly process and emits a diagnosis signal of the presumed cause.
