Investigating flank face friction during precision micro cutting of commercially pure titanium via plunging tests with diamond grooving tools

This study investigates flank face friction while micro machining commercially pure titanium (cp-Ti grade 2) work material considering size effects. It is important to understand phenomena at the tool and surface since they affect integrity of machined parts. A single crystal diamond grooving used in experiments reduce influence cutting edge radius. In addition, plunging type were performed investigate contact on surface. model which based properties proposed contribution adhesion deformation coefficient friction. The results show that for cp-Ti pair, seems be dominant also contributes effect. becomes more during chip formation stage. When effect eliminated, influences rake are shown.
