Research on cutting performance of fine-pitched milling cutters

In response to the prevalent issue of milling vibration during machining, a strategy involving the concurrent engagement of multiple cutting teeth was proposed to mitigate the amplitude of cutting force fluctuations. This method is implemented through the development of fine-pitched milling cutters, and a cutting experiment using the L9(3 4 ) Taguchi method was conducted to evaluate its effectiveness. A comparative analysis was performed using a 4-tooth milling cutter to assess chip morphology, cutting vibration, and surface quality across nine test conditions, in contrast to a 16-tooth milling cutter. The results demonstrate that engaging multiple teeth simultaneously in the milling process effectively reduces vibration. The adoption of fine-pitched milling cutters significantly decreases vibration, enhances surface quality, and markedly boosts milling efficiency. Fine-pitched milling cutters are more adept at high-speed machining, with increased speeds correlating with improved surface quality.
