    Abstract: A method for machining and finishing a metallic member to provide a finished product without any additional process uses a lathe and a milling process. A non-circular metallic member on a worktable is rotated, and lathe tool moved backwards and forwards to machine the peripheral top portion of the metallic member. The path of the lathe tool machines curved surfaces of the top portion of the metallic member. The rotation of the metallic member is then stopped, and a milling cutter is brought to meet the peripheral sidewall of the metallic member. The movement and feeding of the milling cutter is predetermined. The worktable rotates the metallic member to enable one end edge of the peripheral sidewall and then another to face the milling cutter, and have the end edge chamfered by the milling cutter.

  • Patent number: 8707541
    Abstract: A method of roughening metal surfaces of a workpiece such as a cylinder bore of an internal combustion engine to improve the adhesion of layers thermally sprayed thereon. Uniform grooves are formed in the surface and ridges are arranged between the grooves. The grooves may be formed by a process such as turning, drilling, milling or rolling. The ridges are plastically deformed in order to form undercuts in the grooves, with the degree of plastic deformation of the ridges varying regularly in the longitudinal direction of the grooves. Local deformations are produced in the ridge, and these bring about regular undercuts in the groove. This makes it possible to produce the undercuts in identical dimensions with little effort. Furthermore, since the groove is now not completely constricted by undercuts, it can be filled more effectively with spraying material.
