An operating method relating to the correct alignment of a scorer and of a cutting blade so as to obtain a cut without chipping and according to the desired features; said scorer and cutting blade belonging to a cutting assembly of a cutting machine for panels and fitted on a saw carriage with respective central planes, parallel to one another and respective rotation axes, and, in particular, for the correct alignment of said scorer relative to said cutting blade, said scorer being provided with a plurality of teeth having a trapezoidal section, the method comprising the following steps, not necessarily in the order indicated below: a step for measuring the thickness of at least one tooth of said cutting blade and a first distance of said at least one tooth from a reference plane, the latter being parallel to the central planes, of the aforesaid scorer and cutting blade; said measuring steps being carried out by means of a measurement system; said thickness and said distance determining the position of the central plane of said at least one tooth relative to the reference plane; a step for carrying out the measurement of a thickness of at least one tooth of said scorer along a measurement plane, which extends through the section of the teeth of the scorer, by means of the measurement system; a step for measuring the thickness of at least one tooth of said scorer and a second distance of said at least one tooth from said reference plane in correspondence of said measurement plane; said measuring step being carried out by means of the measurement system; a step for adjusting the vertical position of said scorer, according to a direction and senses, which takes place after said measuring step aimed at obtaining, with said scorer in its operating position, a scoring width (LDIC) of said at least one tooth on said scoring plane (PINC) that is compatible with the measured thickness of the aforesaid at least one tooth of the cutting blade; a step for determining the position of the central plane of said at least one tooth relative to the reference plane; a step for laterally adjusting the relative position between the cutting blade and the scorer according to direction and senses, so as to cause the central planes e of said cutting blade and of said scorer to coincide; the method being characterized in that in step the exact position of said measurement plane is defined precisely on the cutting machine in respect to scoring plane (PINC) of the scorer on the working plane, and namely said measurement plane is defined either as coinciding with a scoring plane (PINC) of the scorer itself on the working plane of the cutting machine or is shifted by a known distance relative to said scoring plane (PINC), or else said exact position is defined relative to said rotation axis. a step for measuring the thickness of at least one tooth of said cutting blade and a first distance of said at least one tooth from a reference plane, the latter being parallel to the central planes, of the aforesaid scorer and cutting blade; said measuring steps being carried out by means of a measurement system; said thickness and said distance determining the position of the central plane of said at least one tooth relative to the reference plane; a step for carrying out the measurement of a thickness of at least one tooth of said scorer along a measurement plane, which extends through the section of the teeth of the scorer, by means of the measurement system; a step for measuring the thickness of at least one tooth of said scorer and a second distance of said at least one tooth from said reference plane in correspondence of said measurement plane; said measuring step being carried out by means of the measurement system; a step for adjusting the vertical position of said scorer, according to a direction and senses, which takes place after said measuring step aimed at obtaining, with said scorer in its operating position, a scoring width (LDIC) of said at least one tooth on said scoring plane (PINC) that is compatible with the measured thickness of the aforesaid at least one tooth of the cutting blade; a step for determining the position of the central plane of said at least one tooth relative to the reference plane; a step for laterally adjusting the relative position between the cutting blade and the scorer according to direction and senses, so as to cause the central planes e of said cutting blade and of said scorer to coincide;
