摘要： Disclosed is a method for determining location of a lens machining tool (24) having an offset location according to a first direction (Y) smaller than a first predetermined threshold, including the steps of manufacturing a calibration piece (10) according to a predetermined theoretical geometry by using the lens machining tool for providing a at least partially annular groove in a main surface of the calibration piece, the at least partially annular groove being configured to form at least one sharp edge defining a slope discontinuity on the main surface; measuring a distance between the at least one sharp edge and a turning center of the calibration piece for providing data of geometrical characteristics of the calibration piece; and deducing from the measured data a location of the lens machining tool according to a second direction (X) distinct from the first direction.

摘要： Disclosed is a method implemented by computer for determining a lens blank intended to be used for the manufacturing of a finished optical article. The method includes: —a virtual volume data determining step, during which virtual volume data are determined based at least on finished optical article data representative of the volume of the finished optical article and over-thickness data representative of over-thickness requirements, the virtual volume data are determined so that the virtual volume defined by the virtual volume data includes the volume of the finished optical article volume of the finished optical article and the over-thickness, —a lens blank determining step, during which a lens blank is determined based on the virtual volume data so as to include the virtual volume defined by the virtual volume data.
