Abstract
Disclosed is a method for deducing geometrical defects of an optical article turning machine, including a defect value deducing step, during which at least one geometrical defect value is deduced based at least on an indicative information of an optical and/or geometrical data related to an optical and/or geometrical characteristic of a checking piece (10).
