The larger the tip angle, such as R, means the greater the strength of the blade and the higher the feed rate, but it will increase the cutting force and vibration, which is suitable for rough machining, hard material machining and discontinuous machining;
The smaller the tip angle, such as V, means that the cutting edge strength is worse, but it has better accessibility in profiling, which can reduce the cutting force and vibration, and is suitable for finishing, profiling, longitudinal turning, etc.
