The machining process is one of the production technologies that is almost required for every product. In this modern era, the industry continues to develop. Along with these developments, the miniaturization of machining processes is micro-milling. This research was conducted to determine the significance of cutting speed on the workpiece dimensions on the micro-milling process with pre-cooling of titanium 6Al-4V using the Anova test. The selected cutting speeds are 15, 20, and 25 m/min, and the initial cooling temperatures of the workpiece are 26 ℃, 0 ℃, and -3 ℃. The tools used are solid carbide HRC63 with a diameter of 0.4mm. The results obtained the cutting speed with 15, 20, and 25 m/min variation. The research found that all of those three cutting speeds affect the quality of the dimension of the workpiece with preconditioning temperature. The results obtained that the lowest deviation is at a temperature of −3 ℃ occurs at the three cutting speeds. It means that the cutting speed matters, and pre-cooling the workpiece at a temperature of −3 ℃ is the best. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
