The experimental–numerical approach can be considered more accurate due to the fact that it considers the effect of the tool–chip interface temperature on the shear strength of the work...

... interface could further decrease the COF compared to those that are in the plane parallel to the interface. This may be due to the weaker adhesive ability, smaller real contact area, lower temperature, and higher anti-shearing ability on the interface. This work provides guidelines for the extension...
