Abstract：In order to solve the problem of ultra precision machining of hard and brittle materials,the combination of ultrasonic machining with diamond fly-cutting was proposed,and the ultrasonic machining assisted diamond fly-cutting of nano zirconia ceramics was studied.Firstly,the machining characteristics of diamond flycutting and ultrasonic assisted diamond cutting were analyzed in theory,secondly,mathematical models for the theoretical roughness of the two cases were established,and the influences of various processing factors on the surface roughness of the machined surface were analyzed,finally,the orthogonal experiment was carried out.It was analyzed that the spindle speed,feed rate and cutting parameters cutting depth have processing effects on surface roughness of the nano zirconia ceramic.The results show that ultrasonic assisted diamond cutting technique is suitable for ultra precision machining of hard and brittle materials such as nano zirconia ceramics.
