The workpiece materials used in the experiment were pure Ti and Ti alloy, which are commonly applied in the biomedical and aircraft industries. Although they are attracting increasing interest due to their superior mechanical properties, they are also known to be difficult-to-machine. This study investigated the cutting conditions for realizing minimum tool wear and optimum surface roughness using a TiAlN coated carbide end mill with a diameter of 6 mm, corner radius of 0.5 mm, and four blades in high-speed milling experiments based on the dry cutting process. In this case, peripheral speed was set as the main parameter. Cutting resistance and cutting temperature are also important parameters, but they are difficult to use as indicators for setting cutting conditions directly from the obtained data. Therefore, changing the rotational speed is a practical way to change the peripheral speed, while changing the machining conditions directly from the cutting resistance and temperature is difficult and impractical.
