Abstract: Relative movement between a tool and a workpiece for machining the workpiece with a machine tool is controlled by defining a machine coordinate system (MKS) relative to a machine base of the machine tool and a rotation coordinate system (RKS) relative to the MKS by defining the origin of the RKS in the MKS, defining the orientation of a selected coordinate axis of the RKS in the MKS, defining an axis of rotation around which the RKS rotates in the MKS, defining an angular velocity with which the RKS rotates around the axis of rotation, defining a tool path in the RKS, and controlling the relative movement according to the defined tool path. With this procedure, complex movements of a machine tool, in particular in connection with so-called interpolation turning, can be described or programmed in a relatively simple manner.

Abstract: The invention relates to a method for producing an in particular porous molded ceramic article, which molded ceramic article is optionally reinforced with fibers and/or a semi-finished textile product such as woven fabric, wherein a powder A and at least one further powder B are suspended in a liquid, after which a molded article is formed from the suspension produced in this manner optionally in combination with fibers and/or a semi-finished textile product and the molded article is optionally sintered. It is provided according to the invention that the powders A and B are suspended approximately at a pH value of the liquid at which a viscosity minimum of the suspension is given, whereby high solids contents in the suspension can be adjusted with low viscosities. This makes possible a rapid production of largely crack-free molded articles with advantageously low-defect structures.
