METHOD FOR ROUNDING CURVED PLANE, ROUNDING DEVICE USED THEREIN, AND WINDOW FOR PORTABLE TERMINAL MANUFACTURED THEREBY

摘要

A curved surface processing method, a curved surface processing apparatus used therefor, and a portable terminal-typed window manufactured thereby are provided to process a first and a second curved surfaces formed to a different direction through a single process by cutting a workpiece and rotating a cutter to a first axial direction. A curved surface processing method comprises a step for rotating a cutter to a first axial direction having a cutting line(213) forming a curved surface according to a first axis, and a step for cutting a workpiece by rotating the workpiece to a second axial direction in a state that a cut face of the workpeice(230) is parallel to a second axis.
