Hard, brittle, and easily broken materials, such as quartz, ceramics, bio-ceramics, and inorganic glasses can simply be machined by ultrasonic machining process. In biomedical engineering application, Zirconia (ZrO2) is used for high-quality fracture strength property. Stepped hole shape production on zirconia bio-ceramic with square shape is immensely complicated. The main objective of this research work is to produce square-type stepped hole on bio-ceramic material, i.e., zirconia using USM and also conduct a successful research analysis. The effects of USM process parameters such as grain diameter of abrasive, power rating, slurry concentration, and feed rate of the tool have also been studied on responses, i.e., material removal rate (MRR), flat to flat overcut (FFOC), circularity error of top diameter (CETD), and circularity error of bottom diameter (CEBD) of stepped hole with square shape bio-ceramic material such as zirconia. The effects of USM process parameters on responses have been shown and explained with the help of some graphical representation.
