  • Patent number: 11922956
    Abstract: An apparatus for decoding an encoded audio signal, includes a spectral domain audio decoder for generating a first decoded representation of a first set of first spectral portions, the decoded representation having a first spectral resolution; a parametric decoder for generating a second decoded representation of a second set of second spectral portions having a second spectral resolution being lower than the first spectral resolution; a frequency regenerator for regenerating every constructed second spectral portion having the first spectral resolution using a first spectral portion and spectral envelope information for the second spectral portion; and a spectrum time converter for converting the first decoded representation and the reconstructed second spectral portion into a time representation.

  • Publication number: 20190039202
    Abstract: A honing machine (100) for carrying out honing operations on boreholes, oriented orthogonally with respect to one another, in a workpiece (102), in particular for honing processing of cylinder boreholes and a bearing gate borehole in a cylinder crank casing, comprises a machine base (110) and a round table (130) which is arranged on the machine base and which can rotate about a vertical round table axis (134) and has a plurality of workpiece receptacles which are arranged offset with respect to one another in a circumferential direction at a radial distance from the round table axis, in such a way that a workpiece which is held in a workpiece receptacle can be transported successively to different workstations (140, 150, 160, 170) of the honing machine by rotating the round table.

  • Patent number: 8925198
    Abstract: In a method for the finishing of a crankshaft bearing bore in a cylinder crankcase of an internal combustion engine, starting from a prepared crankshaft bearing bore, a finished crankshaft bearing bore is produced with a prescribable desired size, a prescribable desired structure of the bore inner surface and a prescribable desired position of the bore axis. The prepared crankshaft bearing bore is first finished with at least one finishing tool with a geometrically defined cutting edge and then the honing of the crankshaft bearing bore is carried out. In a final finishing operation with a geometrically defined cutting edge immediately preceding the honing, an allowance of at least 0.4 mm is removed, and the honing tool is introduced into the bore coaxially in relation to the desired position of the bore axis and moved within the bore, an allowance of at least 0.08 mm being removed during the honing.

  • Patent number: 8512095
    Abstract: According to a method for the fine machining of internal surfaces of bore holes in tools by fine boring and subsequent honing, the following steps are executed: Fine boring of at least one bore hole (131) in a tool (130) by means of a fine boring tool (128) of a fine boring device (120) for the creation of a fine bored hole; Transfer of the tool to a machining position of a honing device (140) for the machining of the fine bored bore hole by means of a honing tool (148A) of the honing device; Measurement of the fine bored bore hole with one of the measurement devices (160) allocated to the honing device in the machining position for the creation of at least one bore hole measurement signal representing the properties of the fine bored bore hole. The fine boring device is controlled subject to the bore hole measuring signal.

  • Publication number: 20120184182
    Abstract: A method for fine boring of internal surfaces of bore holes in work pieces as well as a machining plant for executing this method. The fine machining, fine boring, and honing include fine boring of a bore hole of a work piece using a fine boring tool; transferring the work piece into a honing device; measuring the fine bored bore hole with a measuring device associated with the honing device; and controlling the operation of the fine boring device depending on the bore hole measuring signal received by the measuring device. An output fine boring machining, arranged directly upstream of the transfer, is dimensioned as semi-finishing machining, and is carried out with a fine boring tool having at least one adjustable cutting edge. The position of the adjustable cutting edge is controlled depending on the bore hole measuring signal.
