Abstract
Methods of machining a body to produce a chip wherein the body is formed of a material and in a state such that the material exhibits sinuous flow during a machining operation. The methods include providing a layer located on a surface of the body, and machining the body by causing engagement between a cutting tool and the body in a contact region below an area of the surface having the coating layer thereon and moving the cutting tool relative to the body to produce the chip having the layer thereon. The layer reduces sinuous flow in the material of the body.
Claims6
A method of machining a body to controllably produce a chip, wherein the body is formed of a metal, alloy, or metallic material in a state such that the body exhibits sinuous flow during a machining operation, the method comprising:
- depositing a coating material on a surface of the body to form a layer that adheres to the surface of the body;
- and
- machining the body by causing engagement between a cutting tool and the body in a contact region below an area of the surface having the layer thereon and moving the cutting tool relative to the body to produce the chip having the layer thereon;
- wherein the layer is deposited to have a thickness sufficient to provide a surface hardness or ductility that reduces or eliminates sinuous flow in the body.
