N2 - Titanium and its alloys have widespread applications in aerospace and medical fields due to their outstanding mechanical properties and corrosion resistance. However, very limited attention has been focused on machining the microstructure on their surface and the cutting force prediction during machining. Motivated by this, this study used the ultraprecision diamond surface texturing (UDST) process to generate microstructure on the commercially pure titanium TA2 and established a cutting force prediction model. Firstly, the two special characteristics of UDST are systematically investigated by the finite element simulation and the vibration trajectory analysis. And as a core component of the UDST process, a two-degree-of-freedom vibration generator is presented. Considering the periodical vibration motion, tool geometry, and material properties, a practicable cutting force model is next developed for predicting the dynamic cutting force. Finally, two types of unique microstructures are successfully fabricated on the TA2 surface. Experimental results show that the proposed cutting force model agrees well with the measured results, validating its effectiveness.
