Study on Milling force of High Volume Fraction SiCp/Al Composites with Ultrasonic Longitudinal and Torsional Vibration High Speed Milling

摘要

High volume fraction SiCp/Al composites were milled in ultrasonic longitudinal and torsional vibration high speed milling and high speed milling in this experiment, study on effects of different milling parameters (milling depth ap, feed engagement fz, the milling speed vz) on milling force. The results shows that in the same cutting parameters, the three milling force of ultrasonic longitudinal and torsional vibration high speed milling are smaller than that of high speed milling, and milling forces of two milling method increase with the add of the milling depth and feed engagement, but they aren't fold increase. Milling forces of two milling method decrease with the add of the the minlling speed, and the changes become gently when the the minlling speed run up to 170m/min, with the further increase of the milling speed, ultrasonic vibration high speed milling will translate to high speed milling, this is because the torsional vibration is submerged.
