Tribology in Metal Cutting—Some Thermal IssuesSource: Journal of Tribology:;2001:;volume( 123 ):;issue: 004::page 799DOI: 10.1115/1.1353589Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 plane heat source was developed which does not require any assumption regarding the heat partition fraction a priori. Instead, this information is obtained as part of the solution. Similarly, a functional analysis approach was developed to determine the variable heat partition and the temperature distribution at the chip-tool interface due to the frictional heat source. The distribution of temperature in the chip, the tool, and the work material was determined analytically considering the combined effect of these two heat sources in orthogonal machining. The new analytical model was verified for a wide range of Peclet numbers, NPe (0.5–40) using the available experimental data from the literature.
