Abstract
A method for mechanically roughening a cylindrical surface of a workpiece, e.g. the piston-bearing surface of a cylinder sleeve in a cylinder crankcase, by producing a defined microstructure of mutually crossing grooves, and by a groove forming tool, operating with or without material removal. A method in which in a first operation, a groove-forming tool is moved axially along the workpiece surface in such a way that at least one axial groove is machined into the workpiece surface; and in a second operation, following the first operation, the groove forming tool is rotated about the cylinder axis by a predefined rotational angle in the axial position reached in the first operation, whereby at least one circumferential groove crossing the axial groove is machined into the workpiece surface; and in a third operation following the second operation, the groove-forming tool is drawn back axially along the workpiece surface.
