James A. Worachek has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and system for machining process control
    Patent number: 8112170
    Abstract: A method and system for controlling machining processes are provided. The system includes a computer system communicatively coupled to a database. The computer system is configured to receive data relating to manufactured part processes, identify at least one machining process used to manufacture a part and a parameter of the at least one machining process, receive survey data relating to the manufacturing process parameters used during the at least one machining process, and receive identification data for the manufactured part. The computer is further configured to receive data relating to a design of experiment (DOE), determine an low cycle fatigue (LCF) life distribution, identify process parameters that affect the LCF, and determine an allowable range for each identified process parameters for safe operation. The computer system is further configured to output the process window embodied in a specification associated with at least one of the part and the process.
