Abstract: Metal forming tool design or metal forming manufacture utilize computer aided design to generate initial tool geometry and/or to optimize or investigate possible changes in the parameters. Such computer models utilize friction parameters in combination with material characteristics of the tool and blank to assess the process before actual testing. It has been found that such models and assessment possible with such models can be significantly improved by use of a friction parameter representative of the mixed film stage of the lubricant. In a preferred embodiment an approximate average of the mixed film range is used to determine a coefficient of friction used in a computer aided design model that includes a finite element analysis procedure.

Abstract: A method for migrating data between heterogeneous data storage devices within a storage area network is disclosed. A first virtualizer presents stored data as a first virtual disk, and then communicates a managed disk representation of the first virtual disk to a second virtualizer. After receiving the managed disk representation, the second virtualizer virtualizes the stored data from the managed disk representation as a second virtual disk. At such point, the stored data can be progressively migrated from the first virtualizer to the second virtualizer.
