MOLD, CUTTING MACHINE FOR MANUFACTURING THE SAME AND REPLICA MADE THEREFROM

摘要

A mold, a cutting machine for manufacturing the same, and a replica made therefrom are provided to remove Moire phenomenon by permitting the replica to have a random pattern. A cutting machine(300) includes a cutting unit(350), one or more piezo electric elements(320a-320d), and a signal generator(340). The cutting unit cuts a surface of a mold. The piezo electric elements are arranged to provide the cutting unit with mechanical displacement. The signal generator applies electrical signals to the piezo electric elements.
