METHOD AND PROGRAM FOR MACHINING PRESS DIE, PROGRAM FOR GENERATING MACHINING PROGRAM, AND MACHINING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method and a program for machining a press die capable of greatly reducing machining time without requiring skills or causing danger, a program for generating the machining program, and a machining device.

SOLUTION: A method for machining a press die having a punching blade portion B and a second relief section C recessed inwards of the contour shape of the punching blade portion is provided. A tamping tool having at least one or more edge portions on the outer periphery of a tip of its tool body is used, the at least one or more edge portions protruding from the outer peripheral surface thereof and capable of machining when rotating about the axis of the tool body and when moving in the axial direction of the tool body. As the tamping tool is rotated while the axis of the tool body is in an attitude approximately parallel to the plane of the punching blade portion B, the tamping tool is moved relatively along the contour shape of the punching blade portion B, and every time the tamping tool is moved relatively by a predetermined pitch, the tamping tool is moved relatively in the axial direction of the tool body along the shapes of the punching blade portion B and the second relief section C along a punching direction.
