超声振动与切削工艺参数耦合关系的有限元分析
Finite Element Analysis of Coupling Relationship Between Ultrasonic Vibration Parameters and Cutting Process Parameters
摘要
Abstract
The relationship between amplitude,frequency,and cutting speed was analyzed in the context of transverse vibration cutting of Ti6Al4V.Modeling,post-processing,and solution of this process were performed using the Linghang CuttingSim and ABAQUS/Explicit software,respectively.A comparison was made between the vibration effects of the cutting process.The coupling effect of the transverse ultrasonic vibration parameters and cutting process parameters on the velocity coefficient,net cutting time ratio,cutting force,and cutting temperature was investigated using the single variable analysis technique.The findings indicate that the impact of transverse ultrasonic vibration can be assessed by the tool separation characteristics,using the criteria outlined in this research.The effectiveness of transverse ultrasonic vibration is enhanced when the speed coefficient is between 0 and 1,with a decreased net cutting time ratio within a specific range.Ultrasonic vibration reduces the cutting force and cutting temperature.However,its benefits gradually diminish and eventually disappear as the cutting speed increases.The optimal vibration effect is attained under the examined conditions with amplitude of 40 μm,a frequency of 30 kHz,and a cutting speed of 120 m/min,which results in an average decrease in cutting force of 63.75％and an average decrease in cutting temperature of 26.74％.关键词
