Abstract

Ti-6Al-4V is a material that is mostly used in aerospace. In this industry, especially on stabilizer horizontal structure, minimizing burrs height is important, These structures are assembled and drilled. To be economically viable, it is preferred to minimized or even removed burr during drilling process. Aerospace industry needs to drill component in an operation without reprocessing (disassembled, deburred, and fastened). Burr will lead to distortion of work piece dimension, damage to subsurface, and make difficult to handling and assembling of part. Burr occurs during machining because of inoptimum choice of material, tool, and cutting speed. This research uses experimental method by variating rotational speed and material and type of twist drill to find the optimum choice of the parameter and tool for drilling process of Ti-6Al-4V. The quality of drilling process was measured by the height of burr and wear on the tool. The result shows that the lowest burr is 0,085 mm by using HSS-Co twist drill in 500 rpm of speed. The use of HSS-Ti and HSS-Co in high speed will cause chipping worn. Therefore, it is unsuitable to minimize the burr height.
