A 2D orthogonal cutting process of Ti6Al4V was simulated to study the dynamic process of serrated chip formation and to establish the relationship between the tool-chip contact length and the saw-tooth pitch. All orthogonal cut experiments were carried out using a machined Ti6Al4V titanium alloy bar with PCBN tools. The features of the chip back surface and the cross-section surface were analyzed...
We have previously shown that a saw-tooth surface with only horizontal vibration, simple planar and symmetric, can feed along microparts. The microparts move forward because they adhere to the saw-tooth surface more in the backward direction than in the forward direction. Previously, we studied the effect of the pitch of the saw-tooth surface and the vibration frequency on the movement of 2012-type...
