Complex-hole Polishing Combining Abrasive Gels and Abrasive Flow Machining

Rishikesh Tiwari

Abstract

Abrasive flow machining (AFM) makes it simple to polish the intricate holes and the curved surfaces of difficult-to-machine geometries because abrasive media may bend flexibly in this process. Although abrasive media predominate in the polishing behavior of the AFM process, the mechanism of the abrasive media is difficult to grasp due to the highly viscous gels; as a result, many finishing tasks require a lot of time to design the AFM process. The unconventional flow of abrasive gels during complicated hole polishing is evaluated here by studying the power laws of the abrasive gels. First, various abrasive gels are used to complete the intricate holes while waiting for the results of the nonNewtonian flow calculation. Furthermore, due of the irregular abrasive pressures, standard AFM finds it challenging to polish complicated holes with a uniform radial distribution of roughness. Therefore, it is suggested to use a helical tunnel in the AFM process to produce several motions of the abrasive medium and obtain an even surface for the complicated holes.
