The slotting experimental method is not applicable for force coefficients identification considering inclination angle in ball-end finish milling. A new experimental method for force coefficients identification considering the inclination angle is proposed in this research. In this method, the start and exit radial immersion angles φst and φex in any cutting conditions are modeled based on different inclination angles. Based on the research of Gradisek et al., contrary to the slotting experimental method, the position of the cutting element on a ball-end mill edge could be approximately regarded as the only factor that affects the cutting force coefficients. Experiments have been conducted to calculate the cutting force coefficients based on the new method and slotting method respectively. The results show that, for finish milling, the new experimental method for force coefficients identification is better than the slotting experimental method.
