FEA of Micro-Hole Drilling in Stainless Steel Based on DEFORM-3D

In order to better understand the micro-hole cutting processes in stainless steel, the cutting process of 1Cr18Ni9Ti stainless steel was modeled and simulated by FEA (Finite Element Analysis) based on DEFORM-3D software. The influence of rotation speed and feed speed on the thrust force and torque of 1Cr18Ni9Ti stainless steel were analyzed. Meanwhile, the comparisons of simulated results and theoretical calculation results were taken into consideration. It is found that the simulation data from DEFORM-3D agreed well with the theoretical calculation results. It confirms that the results of simulation based on DEFORM-3D have a high level of reliability. The findings of the present study provide a new way to systematically investigate the stainless steel micro-hole drilling process.
