Study on the material removal rate of Nano-ZrO2 ceramics under Ultrasonic vibration assisted diamond fly-cutting
According to the removal mechanism of ductile regime machining of Nano-ZrO2 ceramics and the dynamic characteristics of ultrasonic vibration assisted diamond flying cutting (UVADFC), the model of the material removal rate(MRR) of nano-ZrO2 ceramics under UVADFC and diamond flying cutting(DFC) have been proposed by infinitesimal method,.In this paper, the experiment of three factors and four levels was carded out to study the relationships between MRR and the machining parameters (cutting depth ap, spindle speed n and feed rate c).The results of the experiment shows that UVADFC is a cost-effective method which is applied to the machining of nano-ZrO2 ceramics, and the MRR of nano-ZrO2 ceramics under UVADFC is 1.3-2 times greater than that of DFC, and the degree of the factors significantly influence on the MRR of nano-ZrO2 ceramics are feed rate, cutting depth, spindle speed in a sequence whether it is DFC or UVADFC.The results will shed more light on the material removal mechanism of UVADFC.
