In Ti-6Al-4V titanium alloy micro-machining, since the uncut chip thickness (UCT) is comparable to the radius of the tool cutting edge, there exists a minimum uncut chip thickness (MUCT), and when the UCT is smaller than the MUCT, the plowing effect dominates the cutting process, which seriously affects the machined surface quality and tool life. Therefore, the reliable prediction of the MUCT is of great significance. This paper used Deform to establish an orthogonal cutting simulation model, studied the effect of the dead metal zone (DMZ) on the micro-cutting material flow, determined the DMZ range, and proposed a new method for determining the MUCT based on the DMZ.

- * Results from 32 studies showed that ET significantly reduced the risk of major amputation and complications like fasciotomy compared to OSR, with no major difference in overall mortality rates between the two methods.
- * Patients undergoing ET also experienced a shorter hospital stay and a lower likelihood of nerve injury compared to those undergoing OSR, suggesting ET might be the preferable option for these types of injuries.
