Title:
METHOD FOR MANUFACTURING ELLIPTICAL ECCENTRIC BODY FORMED BY CONTINUATION OF TWO ECCENTRIC CIRCULAR COLUMNS
Document Type and Number:
Japanese Patent JP2017209779
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing an eccentric body at a low cost and with a high accuracy.SOLUTION: A method for manufacturing an eccentric body by which with respect to a work-piece 8 which is cut while rotating, an eccentric body is formed in such a manner that two circular columns, which have a prescribed radius r, are respectively decentered to different positions from a prescribed center point by use of a cutting tool 12 which is movable in a radial direction of a circle drawn by rotation comprises: a first step in which a first circular column 20, which is decentered to a position at which a distance from the center point becomes d, is formed while moving the cutting tool 12 in a radial direction in synchronization with rotation; and a second step in which a second circular column 22, which is decentered to a position which is symmetrical with the first circular column 20 and at which a distance from the center point becomes d, is formed while moving the cutting tool 12 in the radial direction in synchronization with rotation.SELECTED DRAWING: Figure 1
