| PURPOSE: To dispense with extra after machining for improving surface accuracy by setting the shank of a tool being rotated transversely to the feed direction and designing the end face of the tool to adapt to the surface inclinations of the tool having an inclination to the surface of a workpiece at right angles to the feed direction. CONSTITUTION: A workpiece having a concave section is subjected to end milling that acquires a linear contact portion 5, in which the end face 10 of a tool 1 is somewhat conically machined for obtaining such a linear contact portion 5 and the tool 1 has an inclination or cone angle α to the side of the workpiece. Though the cutter shank is held substantially perpendicularly to a feed direction 7 and the linear contact portion 5 is limited only in the range corresponding to half the cutter diameter D, such linear contact may be obtained over the cutter diameter D so that a workpiece is machined to have a concave of a radius of curvature of ρ. The minimal possible radius of curvature of a concave-machined surface is obtained, for a cylindrical workpiece, from the axial projection drawing of the workpiece in the end face figuration and is defined by ρmin =D/(2.sin α). This machining offers improved surface accuracy of the workpiece. | ||||||

| In the context of a method for producing a hollow body (1), a hollow-body wall (3) is created which delimits a cavity (4) of the hollow body (3) and which has a cavity side (5), directed towards the cavity (4), and an outer side (6), directed away from the cavity (4). The hollow-body wall (3) is created in sections by construction of mutually adjoining wall sections (2, 17, 18). After one wall section (2, 17, 18) has been constructed, the constructed wall section (2, 17, 18) is worked on the cavity side (5), before a further wall section (17, 18) is constructed adjoining the constructed wall section (2, 17, 18). A device for carrying out the aforementioned method comprises a machining device (16), by means of which a wall section (2, 17, 18) that has been constructed by means of a construction device can be worked on the cavity side (5), before a further wall section (17, 18) can then be built onto the constructed wall section (2, 17, 18) by means of the construction device. | ||||||

Ein Verfahren zur Bearbeitung von Werkstücken (L) mit einer ersten und einer davon abgewandten zweiten Fläche umfasst die folgenden Hauptschritte: (i) Blocken des Werkstücks vermittels eines Blockmaterials auf einem Blockstück als Bearbeitungshandhabe, mit dem Blockmaterial zwischen Blockstück und erster Fläche, (ii) Bearbeiten des Werkstücks mit geometrisch bestimmter Schneide an der zweiten Fläche zur Erzielung der gewünschten Makrogeometrie, (iii) Bearbeiten des Werkstücks mit geometrisch unbestimmter Schneide (Polierwerkzeuge) an der zweiten Fläche zur Erzielung der gewünschten Mikrogeometrie, und (iv) Abblocken des Werkstücks vom Blockstück. Der Hauptschritt (ii) umfasst hierbei einen Einstech-Unterschritt (ii.2), bei dem mit geometrisch bestimmter Schneide ausgehend von der zweiten Fläche ein umlaufender Einstich erzeugt wird, der durch die erste Fläche hindurch bis ins Blockmaterial hineinreicht, so dass auf dem Blockstück radial innerhalb des Einstichs das Werkstück mit vorbestimmter Randkontur verbleibt. Radial außerhalb des Einstichs entsteht ein Restring, der im Hauptschritt (iii) insbesondere für eine gute Randabstützung der Polierwerkzeuge sorgt.

A free curved surface precision machining tool for precision-machining a surface to be machined with the lower end in contact therewith by rotation around an axis x. It includes a drum-shaped tool having a rotation axis xorthogonal to the axis z and rotationally driven around the rotation axis x. This drum-shaped tool has a convex machining surface in the form of an arcuate rotary body obtained by rotating an arc of a radius r with the center at the intersection O between the axis z and the rotation axis x around the rotation axis x. The convex machining surface contacts the surface to be machined to precision-machine the latter, while the convex machining surface is rotated around the orthogonal axis x so as to disperse the machining position of the convex machining surface. |

| The invention relates to a method and a device for milling freeform surfaces. During milling of 5 axes, a work piece is milled by a tool and/or a miller, in order to produce a desired freeform surface. Said tool is displaced, with respect to the work piece, along at least one tool path and/or milling path defined by support points. According to the invention, a tool vector is defined for each support point of the tool path in the form of forward angles and setting angles. A normal vector is determined for each support point from the forward angles and setting angles, and from a drive vector determined for each support point. The normal vector in each support point of the tool path is used for 3D radius correction in order to compensate for measuring deviations of the miller. | ||||||
