Abstract
A composite member is manufactured by a manufacturing method including adding, on a surface of a base member composed of a first material, a second material different from the first material, using additive manufacturing employing directed energy deposition as an additive manufacturing process. The manufacturing method is performed by placing the base member in a machining area of a machine tool configured to perform subtractive machining. Accordingly, a composite member can be obtained that is manufactured through additive manufacturing and that is in a state in which the composite member can be promptly machined.
Claims8
A method for manufacturing a composite member, the method comprising:
- mounting a first member composed of a first metal material on a fixture of a machine tool in a machining area of the machine tool;
- performing subtractive machining on an outer peripheral surface of the first member by the machine tool while the first member is mounted to the fixture;
- adding a second metal material on a surface of the first member in the machining area, using additive manufacturing employing directed energy deposition as an additive manufacturing process;
- removing a portion of a second member composed of the added second metal material in the machining area;
- and
- manufacturing a third member in the machining area using the additive manufacturing to cover each of the second member and the first member after the removing of the portion of the second member,
- wherein a metal that forms the first metal material is a different type of metal than a metal that forms the second metal material,
- wherein the third member is composed of the metal that forms the first metal material or is composed of a metal that forms the third metal material different from the metal of the first metal material and the metal of the second metal material,
- wherein the subtractive machining on the first member includes using the machine tool to form a plurality of intersecting grooves on the outer peripheral surface of the first member,
- wherein the first memberis tubular, and
- wherein the plurality of intersecting grooves are formed around the entire circumference of the outer peripheral surface of the first member.
