In this study, the cutting parameters were optimized according to the thrust force and operation time in the drilling of Al 2024 T351 alloy, which is preferred in the aerospace industry and therefore subjected to thousands of drilling processes with liquid cooling. Cutting speed (70, 90, and 110 m min −1 ) and feed rate (0.08, 0.1, and 0.12 mm tooth −1 ) were considered cutting parameters. Experiments were performed three tool types (HSS, HSSE-Co5, HSSE-Co5 TiAlN coated). Taksan TMC-700 V CNC vertical machining center with FANUC control panel was used for drilling, and ESIT AX3 load cell and NI cDAQ-9188, data acquisition system, were used for data collection. Signal noise was reduced by applying the exponential smoothing method to all force data obtained in the experiments. The maximum forces in the machining direction ( z -axis) were determined for each hole. The time was calculated during the computer aided manufacturing process. Response surface optimizations, variance analyses (ANOVA), and regression analyses were performed using these determined maximum thrust forces and measured time.
