Abstract
This paper investigates the broaching process of phosphor-bronze (C54400) under different cutting conditions, and the influential factors on cutting force and surface quality are studied. The simulated cutting force implementing the force model based on the energy components also agrees with the results of experiments. In the first part, different cutting velocities of VC = 5, 10, 15, and 20 m/min are studied. In the second part, harmonic vibrations in the form of a sine wave with precise amplitude (A = 1 m/min) and frequencies (F = 55, 65, 85, and 95 Hz) are added in the direction of the cutting velocity. The results revealed that an increase in the cutting velocity from 5 to 20 m/min results in a 40% enhancement in surface quality and a 20% decrease in the cutting force. Additionally, harmonic vibrations of higher frequencies can also contribute to a 35% higher surface quality and a 20% lower cutting force. This study will ultimately improve productivity in industries where broaching is considered the main manufacturing approach, such as automotive and aerospace, in which precision and accuracy are of paramount importance.
