<p>Manufacturing method for a work piece (1), wherein a first manufacturing step is formed into an intermediate state, in a second manufacturing step is introduced into a processing tool (15, 16; 31, 33) in which it is engaged at two opposite sides bz machining parts (18, 21; 31, 33), at least maintaining the work piece (1) in a fixed position, preferably under the exertion of predefined pressure, and in which in a third manufacturing step a peripheral edge part of th work piece (1) is engaged by a third machining part (17; 32) peripheral to one of said oppositely engaging machining parts (18, 21; 31; 33), in which third manufacturing step at least one of the said machining parts (17, 18, 21; 31, 32, 33) is urged towards the work pice (1) along a pressing direction, whereby material of the work piece (1) under influence of pressure exerted by the engagement of the said at least one machining parts (17, 18, 21; 31, 32, 33) plastically deforms and flows into a direction substantially transverse to the pressing direction.</p> |
