ANSYS is Used on Drilling Inner Blind Hole on Deep Hole

In this paper, the process of drilling inner blind hole on deep hole is simulated in the finite element software ANSYS, which can directly reflect the different influence of the cutting force on the bit when drilling. According to the result, designed a deep hole inner blind hole processing auto-device, introduce the design concept and working principle of the device, establish the design model and the mechanical model of the drill bit. Carry out several technical experiments, proved the processing feasibility of the intelligent device; analyzed the problems occurred in processing and the factors that affect machining precision. With experiment results, put forward several deficiencies and improvements for intelligent device, provide important data for future improvement.
