Abstract
Methods, systems, and devices for lathing parts, including lenses such as ophthalmic lenses. In some embodiments a reference surface is machined into a workpiece. In some embodiments the methods include machining first and second surfaces of a lens so that they have the same centerlines.
Claims21
A method of machining a workpiece to be manufactured into an ophthalmic lens, comprising:
- mounting a workpiece to a lathe;
- and
- while the workpiece is mounted to the lathe, machining a first surface of an ophthalmic lens in a first side of the workpiece and a reference surface in the workpiece;
- releasing the workpiece from the lathe;
- re-mounting the workpiece to the lathe by securing the reference surface to the lathe;
- and
- machining a second surface of the ophthalmic lens into a second side of the workpiece after re-mounting the workpiece to the lathe,
- wherein machining a reference surface comprises machining a reference surface that is configured so that the first surface and the second surface have the same centerlines.
A method of machining a workpiece to be manufactured into an ophthalmic lens, comprising:
- mounting a workpiece to a lathe;
- while the workpiece is mounted to the lathe, machining a first surface of an ophthalmic lens in a first side of the workpiece and a reference surface in the workpiece;
- positioning an adhesive potting compound adjacent the first surface and allowing the adhesive potting compound to harden;
- and
- machining a second surface of the ophthalmic lens into a second side after allowing the adhesive potting compound to harden.
A method of machining a workpiece to be manufactured into an ophthalmic lens, comprising:
- mounting a workpiece to a lathe;
- and
- while the workpiece is mounted to the lathe, machining a first surface of an ophthalmic lens in a first side of the workpiece and an outer cylindrical reference surface in the workpiece;
- and
- lathing a second surface of the ophthalmic lens in a second side of the workpiece.
A method of lathing optical surfaces into a workpiece comprising:
- lathing anterior and posterior optical surfaces of an ophthalmic lens into a workpiece without securing the workpiece to an arbor, wherein either the anterior surface or the posterior surface is lathed before the other, and wherein the anterior and posterior surfaces of the ophthalmic lens are rotationally symmetric.
A method of lathing optical surfaces into a workpiece comprising:
- lathing anterior and posterior optical surfaces of an ophthalmic lens into a workpiece without securing the workpiece to an arbor, wherein lathing the anterior and posterior optical surfaces comprises clamping the workpiece directly to the same collet when lathing both the anterior optical surface and when lathing the posterior optical surface.
