Optimization Of AFM Process Parameters In Finish-Machining Of Multiple Holes In Zinc Components Using Taguchi’s Doe Approach

Abrasive flow machining (AFM) is a novel non-traditional micromachining process developed as a method to debur, polish, and radius surfaces and edges by forcing a flowable abrasive media through or across the workpiece. Abrasion occurs only where ever the media flow is restricted; other areas remain unaffected. The technique can be employed to process many selected passages on a workpiece simultaneously, reaching even typically inaccessible areas. A variety of finishing results can be achieved by altering the process parameters. The article identifies the parameters of abrasive flow machining (AFM) that significantly affect the performance measures, material removal (MR) and change in surface roughness (ΔRa), on zinc components bearing multiple holes. Taguchi’s parameter design approach has been applied to investigate the effect of process parameters on output response. Optimization of the process has been carried out for the purpose of improving the process capability and efficiency.
