摘要

The Abrasive Flow Machining (AFM) process is a manufacturing method used for improving the surface finish of engine components with internal cast surfaces to maximize their intended design performance. When compared to the CNC machining process, the AFM process is a near-zero tooling and programming process. Applying the AFM process to cast metal engine components in the gas path, typically results in an increase flow of as much as 30% through the given passage. The results are a dramatic increase in the velocity through the passage that provides for better engine combustion dynamics and gas flow. Applications from small lawn and garden spark ignited gas engines to large diesel truck engines all show promising results when machined using the AFM process. Dynamometer data for both air and fuel components used by both gasoline and diesel engines will be presented and will demonstrate that the influence of using the AFM process on engine components results in increased power and improved emissions, while reducing fuel consumption.
