...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...

... state at about twice the value of the steady-state flux of the tested commercial fluid. Scanning electron microscope imaging was used to further evaluate membrane fouling by each fluid. The machining capabilities of the designed fluid were examined in terms of cutting forces and machining temperature...

... curls out of contact with the tool and progressively extends outward and away from the cutting edge in conjunction with an increase in the length of contact as cutting progresses. The sticking and sliding zones are unchanged when these pure metals are machined with tungsten carbide tools. Two types...

...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...

...H. D. Espinosa; A. J. Patanella; M. Fischer Understanding high speed machining processes requires knowledge of the dynamic friction response at the tool-workpiece interface, the high strain rate response of the workpiece material and its fracture mechanisms. In this paper, a novel experimental...
