Abstract

PURPOSE: To simplify machining of an object into a non-spherical lens by grinding together the grinding tool and the machined object under the movement to model after a matrix in conical shape or another which is easy in the manufacturing.
CONSTITUTION: A modeling edge 2 has a locus for a hyperbola, for an ellipse, or for a parabola drawn by modeling a modeling edge 2 after a matrix 1 in conical shape or another which is easy in the manufacturing. Then, the surface of a machined object 7 is non-spherically machined into a hyperbolic face or another by moving a grinding tool 4 attached to an axle body 3 restricted by hyperbolic or elliptic or parabolic locus which is drawn by the modeling edge 2.
