Zusammenfassung:	The method comprises the following steps: - disposing at least a cutting (62) on a cuttings support surface (67); - placing a measuring apparatus (63) over the support surface (67), the measuring apparatus (63) facing the cutting (62), at a distance from the cutting (62); - measuring a first distance (d 1 ) between a reference plane and the support surface (67) in the vicinity of the cutting (62) along an axis (A-A') transverse to the support surface (67) using the measuring apparatus (63); - measuring a second distance (d 2 ) between the reference plane and the cutting (62) along the transverse axis (A-A'), using the measuring apparatus (63); - calculating a representative dimension (d zz ) of the cutting based on the difference between the first distance (d 1 ) and the second distance (d 2 ).
