Abstract: A simulation and modeling method for micro turn-milling cutting process was investigated to predict the impacts of cutting speed and cutting depth on cutting force. Based on material Johnson-Cook constitutive model and chip separation criteria, the finite element model was established in ABAQUS simulation application, then the model analysis and experiment verification was conducted. The results indicate that the simulation model can predict the value and regularity of cutting force, which can provide guidance on process optimization and machining accuracy control.

Abstract: Turn-milling technology can replace turning with milling to high speed machining rotationally body parts. So, micro-turn-milling has superiority on the productivity and the quality of workpieces, and is more suitable to machine micro-shaft parts and desirable miniature parts based on the turn-milling technology. Micro-turn-milling can be used for the machining of micro-parts in its hardened state. In this paper, the influence of cutting parameters on surface topography and tool wear is presented in micro-turn-milling of micro-screw. The interaction effect of parameters to surface topography and tool wear is investigated. The results show that micro-turn-milling technology has its peculiar advantages in realizing high-speed cutting and ensuring machining quality.
