Abstract: A process for machining a blank from all directions with a machine tool, such as a milling machine, involves the machining from all directions being based on a three-dimensional template. In a first step, the three-dimensional form and, if need be, also the surface finish of the three-dimensional template may be automatically measured, and the associated data may be saved. In a second step, a blank may be held by at least one clamping adapter and a first region is brought into its final, ready to use partial form by the machine tool or the milling machine using said data for numerical control. In a third step, the partially machined blank may be held by at least one clamping adapter in the first, finally machined region and the remaining region may be brought into its final, ready to use overall form by the same machine tool or milling machine.

Abstract: An end mill 10 is a tool for milling a metal block such as a metal mold and is placed in a machine tool such as a milling machine when in use. The end mill 10 is used to provide a rotary milling cutter and a milling method using the same, in which it is possible to perform orthogonal milling and pocket milling to efficiently form four corners with small radius, without repeatedly milling using a small-diameter end mill. The end mill 10 has two cutting edges 11a and 11b at its distal portion, and an edge angle D1 formed by the two cutting edges 11a and 11b is 70.53 degrees.

Abstract: Relative movements of a tool and a workpiece are controlled by moving a tool axis in all spatial dimensions for the material-removal machining of the workpiece to produce a desired target contour of the workpiece by a sequence of relative movements along a tool trajectory of the tool. The tool trajectory is subdivided into a multiplicity of target segments along which the tool is in engagement with the workpiece so that the orientation of the tool axis is consistent within a target segment, while the orientation of the tool axis is variable over the entire tool trajectory, and a respective and point of a target segment is connected by a linking pivot movement, during which the tool does not engage the workpiece and in which the orientation of the tool axis is altered, with a starting point of a further target segment.

Abstract: A milling method is for producing milled structural components of materials that are difficult to machine by chip-cutting. A milling tool with a tool radius is rotationally driven about an axis of the milling tool to ensure a central rotation thereof, whereby a reference point of the milling tool preferably lying on the axis is moved on several curved paths, whereby the paths preferably comprise different curvatures, and whereby the milling tool is moved on the paths with a radial miller feed relative to the material. The curvature at each path point of each path is determined in such a manner that an optimized or maximized circumferential contact of the milling tool is ensured for each path point.

Abstract: Airfoil blades are machined in a workpiece using a circular machining tool defining a machining ring having inner and outer circumferential surfaces. The airfoil blades are created by generating engagement movements between the rotating circular machining tool and the workpiece so as to define a concave side of an airfoil with the outer circumferential cutting surface of the machining ring and a convex side of an adjacent airfoil with the inner circumferential cutting surface of the machining ring.

Abstract: A milling method is provided for the manufacture of components composed of difficult-to-cut materials for turbomachines, aircraft and spacecraft by producing recesses with one or more side walls. An end milling cutter which cuts at the circumference and at the tip and has a tip contour which is rounded towards the circumference is used as the rotating milling tool. In addition to rotation about its axis, the milling tool performs an eccentric orbiting motion about an orbital axis spaced apart from its axis. The opposite senses of rotation lead to downcut milling, and the orbital axis performs a translational advance motion on a straight and/or curved path transversely to its longitudinal direction, with or without a swivelling motion.

Abstract: A milling method is provided in which a finished part of any desired contour is milled from a blank of any desired contour by the milling tool being guided on a continuous, spiral guide path from the blank continuously to the finished part. In this case, material is continuously removed during the milling operation without ever lifting the tool or clamping the workpiece in place again. This results in a reduced machining time of the workpiece. The continuous, spiral guide path permits a harmonic change of form from the blank to the finished part with smooth guidance of the tool. The method can also be carried out with ceramic tools.

Abstract: A method for forming at least a portion of the edge 12, 14 of an airfoil 10 using a cutting tool 164 is disclosed. Various details of this method are developed which enable incremental removal of material by repetitively moving the tool with respect to the edge while positioning the tool with respect to a spanwisely extending airfoil R.sub.5, on the airfoil.

Abstract: A structural component having a twisted profile or cross-section, such as a arge scale wing for a windmill or for a helicopter, has an upper portion and a lower portion intimately bonded to each other along an interface formed by two separation surfaces. A longitudinal axis extends in said interface. The interface is defined by simultaneously twisting or rotating and longitudinally moving a polygonal line (PZ) relative to the longitudinal axis while a central portion of the polygonal line extends perpendicularly to the central axis. The machine tool for machining the separation surfaces has a tool carrier (14), and a carrier support (20) for holding the tool carrier (14) in such a manner that the tool carrier is tiltable about the longitudinal axis of the interface. Simultaneously the carrier support is movable in the direction of the longitudinal axis (A).
