Aerospace monolithic component was composed of different typical characteristics

the research on the machining properties of the monolithic component can be implemented by studying the machining properties of typical structure characteristics

respectively

and then combining characteristics to study the correlation of characteristics. Virtual machining is an important simulation method to study the machining process. In this paper

the machined part

which was made up of typical features

was constructed in virtual environment. The two high performance machining strategies of high feed milling and high cutting depth milling were applied to machining simulation experiments

respectively. The experimental results show that the main cutting force

cutting power and material removal rate under high feed milling strategy are obviously less than that of high cutting depth milling strategy

and the specific energy consumption of high feed milling strategy has obvious mutation point at the corner characteristic. It is found that the material removal rate of high feed milling strategy has a large deviation from the theoretical value due to the frequently up and down of the feed speed at the corner characteristics.
