Objective: The onset of the empirical approach presented in this paper leads to evaluation on the Influence of the Feed Rate, Cutting Speed, and Tool Material on Torque while drilling Prepared Hybrid FRP Laminate using CNC programmed machine.

Findings: The influence of cutting condition (feed rate, cutting speed and tool material) on torque were studied and examined.

Technique: Design of experiments (DOE) was conducted for the control analysis of the drilling parameters on the response variable (Torque or Twisting Force) by utilizing Taguchi’s L27 array the design obtained through Multilevel factorial design in commercial software Minitab 17 to find whether the response variable is minimized by major and/or minor control factors.

Result: The percentage deviation of Cutting Speed signifies that torque was least affected rather than other considered factors. The minimum torque was reached in case of cutting speed compared to feed rate and tool material at all levels of factors studied through distinctive main effects plots.
