  • Patent number: 8326448
    Abstract: A method and a device for operating a machine tool are disclosed, wherein a machining operation of the machine tool is controlled by a parts program by storing a simulated configuration of the machine tool in the parts program, determining an actual configuration of the machine tool, comparing the actual configuration with the simulated configuration of the machine tool stored in the parts program, and generating a warning message if the actual configuration is not in conformance with the simulated configuration. This prevents errors in the machining process resulting from a discrepancy between the configuration of the machine tool used in the simulation of the parts program and the configuration of the actual machine tool during the actual machining operation.

  • Patent number: 8314053
    Abstract: The invention relates to a component that is suitable for use as a sliding bearing. The invention further relates to a method for the production of said component. The design of the component according to the invention provides a layer of a light metal material (13), which is provided with an oxide layer (15) containing pores (16) in the direction of the sliding surface (23) of the component. A hard material (18) is placed in the pores, which greatly increases the firmness of said layer region, thus creating the mechanical firmness for use as a sliding bearing. In order to counteract the tendency of said firm layer region to experience brittle failure, the oxide layer (15) is coated with a solid lubricant layer (20). Said solid lubricant layer comprises a metallic, ductile matrix (21), which distributes a force (F) acting at certain points over a larger surface region (b).

  • Patent number: 8315826
    Abstract: In a diagnostic method for at least one ball bearing, in particular for an angular-contact ball bearing for bearing a rapidly rotating spindle, mechanical vibration caused by the respective angular-contact ball bearing is acquired by at least one vibration sensor and outputted as a corresponding vibration signal. At least one bearing characteristic, fundamental kinematic frequency dependent on a current bearing rotational frequency is determined by computation. A corresponding bearing frequency in a measurement frequency spectrum of the respective vibration signal is determined by measurement. A first diagnostic message is output when at least one of the determined bearing frequencies deviates by a respective prescribed frequency deviation from the corresponding computational fundamental kinematic frequency.

  • Patent number: 8312629
    Abstract: In a method of making a tubular support bar for a dashboard support, a sheet metal blank is placed in a first forming tool and pressed in a first shaping step by a ram into a U-shaped cavity of a first bottom die to form a U-shaped member. While remaining in the first bottom die, the U-shaped member is provided with connecting elements in the form of weld nuts by a automated placement device. Subsequently, the U-shaped member is transferred to a second forming tool and undergoes a second shaping step between a top die and a second bottom die to form a slotted tube. The longitudinal edges of the slotted tube are then joined together to form the support bar.
