Experimental investigations on AL7075 gear in abrasive flow finishing

Abstract

Abrasive Flow Finishing (AFF) is a novel Surface Finish (SF) technique that prevents the reshaping of parts' internal surface layers in a wide range of exercises. Semisolid silicon oil with abrasive particles is flowed through the workpiece tooth to achieve a smooth finish. Abrasion occurs over the AL7075 gear tooth while medium passes through the highly closed passage. Flow pressure, number of passes, abrasives mesh size composition and type of tooling, and fixture designs all impact AFF and are studied using optimal process output like SF and Material Erosion Rate (MER). Due to sufficient and a wider range of cycle levels for a larger erosion rate, the greatest level of material erosion rate was reached at 125 bar pressure, mesh size of 100#, and 6 cycles. SF and MER are used as outcomes in the optimization approach. The Taguchi method, planted L9 orthogonal array, has been established for experimental design and machining performance.
