Abstract
Provided is a method of manufacturing an elbow, including: a first cutting step of cutting a material by relatively moving a cutting section of a cutting tool, which is formed of at least a part of a substantially spherical shape, along an inner side surface of the elbow to be finished in a direction from a first end surface to a second end surface of the material; and a second cutting step of cutting the material by relatively moving the cutting section along the inner side surface of the elbow to be finished in a direction from the second end surface to the first end surface of the material.
Claims9
A method of manufacturing an elbow, comprising:
- a cutting step of cutting a roughly formed elbow to form an inner side surface of the elbow to be finished by relatively moving a cutting section included in a cutting tool, which is formed of at least a part of a substantially spherical shape, along a center line of the elbow to be finished in a direction from a first end surface to a second end surface of the roughly formed elbow;
- and
- a moving step of relatively moving the cutting section along the center line of the elbow to be finished in a direction from the second end surface to the first end surface of the roughly formed elbow,
- the cutting section having a diameter substantially equal to an inner diameter of the elbow to be finished.
