Study on boring and drilling with vibration cutting

In this paper, vibration cutting (VC) has been applied to boring and drilling processes using a vibration device we developed. We analyzed the effect of vibration in boring by investigating the surface roughness of workpiece with the help of Taguchi method and analysis of variance (ANOVA). It has been shown that the utilization of VC in boring improves the surface roughness prominently. The shading-area method we proposed can be employed as a simple and feasible approach for the analysis of burrs in intersecting holes. High-frequency vibration boring can reduce the burr formation in intersecting holes effectively. The experimental results show that the utilization of VC reduces the burrs in intersecting holes noticeably.
