AB - Deep lunar drilling is an effective means of obtaining complete lunar profile  samples and high quality exploration data, which is of great historical  importance in promoting the development of China's lunar exploration. In  this work, a finite element model of moonstone is constructed and a  simulation study of drilled moonstone is carried out. In addition, the  Drucker-Prager model to describe the intrinsic properties of moonstone is  selected, based on the Abaqus finite element software, to complete the  numerical simulation of lunar rock cutting by setting different drill feed  rates to study their effects on the drill rock fracturing process. The  simulation results show that at constant speed, the drilling displacement  increases with increasing feed rate. To avoid a drill stop, it must be  ensured that the feed speed is at least above 1.6 mm per second. The  simulation results show that the drilling offset increases with increasing  feed rate.
