Abstract
Methods of machining a body to produce a chip are provided 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 and the chip is formed primarily by laminar flow.
Claims17
A method of machining a body to controllably 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 method comprising:
- providing a layer located on a surface of the body;
- and
- machining the body to remove a surface portion of the body having the layer thereon by causing engagement between a cutting tool and the body in a contact region below the surface of the body having a portion of the layer thereon and moving the cutting tool relative to the body to remove the surface portion of the body and the portion of the layer thereon, produce a final surface of the body, and produce the chip having the portion of the layer thereon;
- wherein the layer reduces sinuous flow in the material of the body.
A method of machining a body to controllably 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 method comprising:
- providing a layer located on a surface of the body, wherein the layer is provided by performing a surface deformation process to induce a strain in the surface of the body and form a hardened layer;
- 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 reduces sinuous flow in the material of the body.
