Abstract:
1. A method of manufacturing an optical component or a molding die for the optical component, the method comprising the steps of: cutting a surface of a work with a tool by rotating the tool around its axis with a cutting edge facing outward and moving in a circle to cut the work surface at a point of the circle while relatively moving the tool and the work in a line direction crossing to the axis of the tool at a predetermined feed speed; and cutting the work surface in a next line after relatively moving the tool and the work in a pitch direction perpendicular to the line direction by a pick feeding distance; wherein the above steps are carried out under the following conditions: 10000≦S≦30000; (F/S) f where S: tool rotation speed (rpm); F: feed speed (mm/min); D: rotating radius of a cutting edge of a tool (mm); f: pick feeding distance (mm); r: nose radius of a cutting edge of a tool (mm).
