摘要： The invention relates to a machining method for machining a curved workpiece surface (210) of a workpiece (200), in which a roll forming operation is carried out. At least one roller element (180A, 180B, 180C) of a machining tool (100) is rolled under a contact pressure against a segment (198) of the curved workpiece to be machined. An outer surface of the roller element comprises a rough surface structure in at least one working segment (190A, 190B, 190C) intended for rolling contact with the workpiece surface. The contact pressure is set so that a rough roll-formed structure is generated when rolling by locally deforming the workpiece material without removing material in the area of the workpiece surface being machined. The machining method can be used, for example, for machining the inner surface of a hole in a workpiece, in particular for roughening the workpiece surface for subsequent coating. The invention further relates to a machining tool and to a workpiece thus produced.

摘要： In a method for fine processing of an internal surface of a borehole in a work piece, which is composed at least in the region of the borehole substantially of a light metal material, a processing tool performs during at least one processing operation a working motion within the borehole to be processed. The method comprises a friction strengthening operation, wherein a processing tool is used which has at least one friction element, which has at least one contact surface provisioned for friction contact with the internal surface. The friction element is moved over the internal surface at a relative speed with respect to the internal surface and at a friction-inducing pressure so that under the influence of dynamic friction and pressure in the region of the internal surface, a friction strengthened layer is produced which is induced essentially by friction and pressure. The method can be used in particular for processing cylinder running surfaces in the production of light-metal engine blocks.
