Investigating microstructure effects of heat-treated commercially pure titanium (cp-Ti) based on mechanistic modeling of micro milling

摘要

Microstructural features such as grain size, grain morphology, and phase fractions have significant influence on process outputs of machining processes. During micro end milling where feed per tooth and depth of cut values are set comparable to grain size, process material interactions become more significant. The goal of this study is to investigate the influence of microstructural effects on process outputs during micro milling of cp-Ti work material. Micro milling experiments are performed to observe the process outputs as a function of grain size and grain morphology and a mechanistic approach has been used to explain their effects during micro milling.
