Method for manufacturing an oscillating member

A method for manufacturing an oscillating member (2) having a structural characteristic with a predetermined value, the method comprising the following steps:

• a) forming (40), in a plate (1a, 1b), said oscillating member (2) according to dimensions that are different to the dimensions necessary to obtain said oscillating member (2) having the structural characteristic of the predetermined value;
• b) determining (31) a value of a structural characteristic of the oscillating member (2) in the plate (1a, 1b) from a generation substep (39) in which this value is generated on the basis of a predictive algorithm applied by a computer (8) to process at least one characteristic of an identified resonance frequency of the oscillating member (2) when it is exposed to vibratory excitation in an optical measurement substep (38);
• d) calculating (40) a dimensional correction to be applied to said oscillating member (2) formed, on the basis of the value of the structural characteristic determined;
• and
• e) modifying (42) the dimensions of said oscillating member (2) formed, on the basis of the dimensional correction calculated to obtain the oscillating member (2) with dimensions smaller than the dimensions necessary to obtain said oscillating member (2) having the structural characteristic of the predetermined value.
