... of aluminum alloy. BUE is responsible for early tool breakage due to excessive material build up from the machined part on the cutting face, leading to problems of shape irregularity and tool-tip breakage. Thus, diamond-like carbon (DLC) was deposited and tested to verify cutting precision in aluminum alloy...

They reported that at lower attack, angles rubbing mode is active, while at higher angles, chip formation or machining takes place ( 33 34 ). Under lubricated conditions, when Al–Mg alloy pins slide perpendicular...

...Michael R. Lovell; P. Cohen; Pradeep L. Menezes; R. Shankar When machining miniaturized components, the contact conditions between the tool and the workpiece exhibit very small contact areas that are on the order of 10 − 5 mm 2 . Under these conditions, extremely high contact stresses are generated...

...R. Komanduri, Fellow ASME; Z. B. Hou This paper addresses two fundamental thermal issues of tribology in orthogonal machining with a sharp tool, namely, the nature of the apparent heat partition in the shear plane and the variable heat partition at the chip-tool interface. A new model for the shear...
