Abstract

Titanium alloys have been spotlighted in numerous industries owing to their superior mechanical properties, such as high specific strength. However, the high heat and wear resistance of titanium alloys also lower their machinability and limit the wider application of the material. Many researchers have investigated the processing of titanium alloys, and it is required to evaluate the effectiveness and efficiency of developed technologies. From this perspective, this research studied sustainability in titanium alloy machining. The power consumption of the machine was measured during the process and analyzed in terms of process parameters and individual machine components. Here, an end mill specially designed for titanium was also investigated and compared with a general-purpose cutting tool. Based on the experimental results, a model was constructed to predict the power consumption of the overall process. It is expected that this study will contribute to the more effective and efficient processing of titanium alloys.
