Studying Material Removal in Abrasive Flow Machining by using SiC

Abstract

Finishing of complex, miniaturized parts, especially of internal recesses is very difficult and time consuming process.
Abrasive Flow Machining (AFM) is an appropriate finishing process for such finishing requirements. It uses abrasives
laden polymeric putty with other ingredients to polish the surfaces. This medium is extruded back-and-forth over the
surface employing the hydraulic pressure system through the low carbon steel as the workpiece and SiC as abrasive
material. In this Paper, propose multiple regression model (MRM) by using response surface method (RSM) in Minitab
program, to predict material removal. The R2 (ability the Independent values to predict the dependent values) of the
predictive model is 92.3%. From the applicant multiple regression model equation, the extrusion pressure (X1) is the
most significant machining parameter to influence material removal (MR).
