Prediction of Nonlinear Micro-Milling Force with a Novel Minimum Uncut Chip Thickness Model [PDF]
Micromachines, 2021 The minimum uncut chip thickness (MUCT), dividing the cutting zone into the shear region and the ploughing region, has a strong nonlinear effect on the cutting force of micro-milling.

Determination of the Minimum Uncut Chip Thickness of Ti-6Al-4V Titanium Alloy Based on Dead Metal Zone [PDF]
MicromachinesIn 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 ...

The International Journal of Advanced Manufacturing Technology, 2022 AbstractThe minimum uncut chip thickness (MUCT) is an important phenomenon observed both in orthogonal and oblique cutting. Rounding the cutting edge influences the initiation of the cutting process and chip formation. In a previous study, the authors presented a theoretical analysis and experimental validation on the effect of edge inclination angle ...
