Abstract
A method of producing a finely structured body comprised of a plurality of stacked, cut sections of foil at least one of which is provided with grooves. A machinable foil is wrapped around a cylindrical mandrel of a lathe to overlap opposing edges. The overlapped edges are clamped into an axial recess of the cylindrical mandrel by means of a clamping means and a plurality of grooves cut into the surface of the foil by means of at least one shaping diamond positioned in a feed which is finely adjustable. The plurality of grooves each have a groove length, a groove width, and a cross-sectional shape that is constant over the groove length and is freely selectable. Then, the grooved machinable foil is cut into cut sectoins and the cut sections are stacked. The plurality of grooves have a form precision such that, for groove lengths of more than 1000 .mu.m, the groove width has an accuracy of about .+-.1 .mu.m for land widths which equal or exceed about 15 .mu.m. Alternately, the machinable foil may be stretched over a vacuum clamping means comprised of a ground, sintered metal plate positioned on a work table which is movable in two mutually perpendicular directions X and Y and a plurality of grooves cut into the surface of the machinable foil by means of at least one shaping diamond positioned on a cutting spindle and adjustable in a direction Z.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
