Extruding better performance. (Focus on Abrasive Machining).

Proper application of Extrude Hone's abrasive paste could improve automobile engine performance up to 6 percent. With funds from the National Institute of Standards and Technology's (NIST) Advanced Technology Program, Extrude Hone, Irwin, PA, and joint venture partners, which include Ford Motor Co. and General Motors, have developed an advanced process control system that measures the flow characteristics of parts as they are machined. The process makes possible performance enhancing techniques that had been previously reserved for costly aircraft engines and specialty cars. The key to the program is computer software that uses a neural network model to adjust media flow for machining of internal surfaces on parts such as engine intake manifolds. The $7.9 million program at Extrude Hone will extend understanding of the effects of abrasive flow machining on engine performance. Long term benefits include a projected increase in annual U.S. gross domestic product by $142 million and 1,800 new manufacturing jobs. Details of the collaborative project and its benefits can be found in a 76-page report, Economic Impact of Flow Control Machining Technology, publication NISTIR #6373, which is available free from NIST's website in the Adobe pdf file format.
