Abstract

Use of conventional drilling process have been utilized by academia and industry alike for making holes in difficult to machine materials like titanium alloys. However nowadays helical hole milling process has been adopted due to the advantages it brings in. This work therefore aims to evaluate the traditional drilling process against the newer helical milling process for hole making in titanium alloy. The evaluation was carried out considering the thrust force, surface roughness, hole diameter and machining temperature. The morphology of chips generated and the burr formation were also investigated. The comparison of thrust force and machining temperature were found to be lower for the holes processed using helical milling process. The finish of the machined hole surfaces was better when helical milling process was used. Additionally, helical milling of holes resulted in relatively diametrically accurate and burr free holes. The preliminary results obtained show that helical milling process can be a promising alternative to traditional drilling process for machining difficult-to-machine material like titanium alloy provided the productivity of the process can be improved.
