The prime aim in this work is to compare material removal rate (MRR) during CNC drilling of innovative hybrid epoxy composites reinforced with natural fiber (10%) and nano carbon particles (5%) to plain epoxy.: The hand-layup technique was used to create the samples for both groups. The samples were prepared according to specifications, and drilling operation was performed in a CNC (vertical) machine with a pretest g power of 80%. The MRR (material removal rate) of the samples was evaluated and compared between the groups by doing twenty experiments (each with one repetition) per group, for a total of 20 experiments per group. To assess the material removal rate, T-independent tests were done using the SPSS statistical software programme. According to the material removal rate data, Group 1 (75 wt%)/ Sustainable Ramie fiber (10 wt%)/ nano carbon particles (5 wt%) had an average of 0.43511 mm³/sec, while Group 2 (plain epoxy) had an average of 0.15511 mm³/sec. The mean variance of MRR between Group-1 and Group-2 is determined to be different (significant of p=0.00, which is P<0.05) based on results of T-test statistical analysis. There is a significant and statistical difference between the two groups under study. Within the limitations of this study, it is obvious that the addition of reinforcements such as Sustainable Ramie fiber and nano carbon particles has a substantial impact on MRR improvement.
