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.

Abstract: The invention relates to a multi-edged machining tool for the post-machining or precision machining of bores. The tool has at least one cutting insert with a pre-determined nominal diameter measurement and with cutting edges that are distributed substantially uniformly around the periphery, in addition to a guide body assembly that is axially offset in relation to said edges. The guide body assembly can be an integral component of a substantially cylindrical guide body that consists of a solid carbide. In some embodiments, said guide body forms at least n helical guide ribs which are equidistant around the periphery and which have a nominal diameter substantially smaller than the nominal diameter measurement of the cutting insert by a value equating to double the dimension of the lubricant gap that is formed during the operation of the tool.

Abstract: A shapeable and re-shapeable material for orthopedic devices is formed of an amorphous, thermoplastic forming a matrix layer, for example of PMMA which is polymerized at room temperature, and of reinforcing fibers inserted therein. It is possible to provide several matrix layers, bonded in a laminate-like manner, respectively provided with fibers. The material can be deformed in the course of producing orthopedic devices and can be re-deformed in the course of using the device by being respectively heated to less than 200.degree. C. A mixture of the reaction components of the plastic material is placed in a mold for producing the shapeable material, the fibers are placed on it and the polymerizing plastic material is compacted. Additional mixture and additional fibers can be added during the polymerization of the first matrix layer in the same manner to form further layers of the laminate-like shapeable material.
