Tool wear investigation in drilling titanium alloy

Abstract

Abstract During the process of drilling a titanium alloy it can lead to several sources of difficulties. At tall temperatures, titanium can converted chemically lively besides will tend to react with most tool materials such as steel, copper, and other objects. In this study, solid carbide drill will be accustomed drill titanium alloys using different cutting parameters. This research is an experimental study in which to show a relationship between cutting constraints for example feed speed and spindle speed during tool wear and to see developments in the study of wear of solid carbide bit drill bits. The experiment was carried out using a CNC milling machine when drilling on titanium alloys with dry cutting conditions. The three types of testing will be carried out using different cutting parameters namely spindle rapidity of 2387 rpm, 3183 rpm and 3979 rpm then food speed of 29 mm / minute, 48 mm / min, and 72 mm / min have been used with the same type of swivel solid carbide drill. The results show that by applying different or thrilling cutting parameters for spindle speed and feed speed is very influential on the presentation of the bit tool when drilling titanium alloys. Experiment 1 shows the best tool life performance results after drilling Titanium in lower cutting parameters 2387 rpm and 29 mm / minute. Based on observations, it shows that lower cutting parameters must be used once drilling the Ti-6Al-4V to achieve a better act than before.
