METHOD FOR OBTAINING AN OPHTHALMIC LENS |
摘要 |
<p>A method for obtaining an ophthalmic lens, includes:—the step of selecting a material that displays a threshold of pinhole formation during a machining step of a finished surface (20) in a material-removing depth (D) of 0.07 mm, which is at least 15% higher than the threshold of pinhole formation during a machining step of a finished surface in a material-removing depth (D) of 0.22 mm;—the step of selecting a set point for finishing depth of cut (A) between 0.015 mm and 0.075 mm; and—the step of selecting a set point for finishing feed between 85% and 99% of the threshold of pinhole formation for the material-removing depth (D) given by the sum of the selected set point for finishing depth of cut (A) and the blank roughness (B′).</p> |
