Most of polishing process are being manually conducted by operators, depending on their skill and experience, However, manual polishing is expensive, time consuming, labour intensive, and error prone[1,2].Therefore, Manual and old conventional machine polishing methods are gradually becoming obsolete, the need for better part quality and flexible, more efficient, and cost effective manufacturing and finishing methods, integrated with computer science, has encouraged new mechanized polishing approaches and the automation of polishing process[3,4].
