Workpiece Surface Integrity of GH4169 Nickel-Based Superalloy when Employing Abrasive Belt Grinding Method

Abstract:

The use of GH4169 nickel-based superalloy for the manufacture of gas turbine engines components for aerospace/energy applications has become a routine exercise. However, components with complex designs specifications might pose manufacturing challenges especially when grinding processes are needed to enable their compliance with tight industrial standards for workpiece surface integrity. Information on grinding processes for such sensitive industrial applications is scarce. The paper reports on the influence of grinding methods/strategies on the quality and integrity of workpiece surfaces obtained after abrasive belt grinding methods on GH4169 nickel-based superalloy. The influences of grinding speed, contact pressure and oscillation frequency on surface roughness were discussed. The performance of the abrasive belt and surface topography were discussed. As a result, the maximum surface roughness of Ra is 0.072μm, and have a good performance of the abrasive belt, it could be concluded that abrasive belt grinding might be considered as a viable process for grinding aero-engine components.
