Tool temperature values are determined using finite element modeling. These temperatures are related to tool wear measured after diamond turning tests on a low carbon steel workpiece to determine constants in the Arrhenius-type model. Measured tool wear shows a transition in worn tool shape from low speed (1 mm/s) to high speed (4 m/s) machining tests. Model results show a minimum value of wear per cutting distance occurs at a cutting speed of 2.5 m/s. The model also gives an activation energy between 25.0 kJ/mol and 29.3 kJ/mol. In addition, this model is used to explain experimental results obtained by others researching chemical wear of diamond.}, number={1-2}, journal={WEAR}, author={Lane, B. M. and Dow, T.

An electron-beam-induced deposition (EBID) method reported previously is further developed and improved to measure diamond tool profiles using a field emission scanning electron microscope (SEM). The edge radius and wear land length for new and worn diamond tools were derived from analysis of the EBID-SEM images.

Wear mechanisms for diamond tools can be either abrasive or chemical in nature, or a combination thereof. Differentiating the affects of these wear mechanisms can be accomplished by measuring the wear geometry of the cutting edge as a function of cutting distance. Orthogonal cutting experiments using 6061 aluminum and 1215 steel were conducted to illustrate abrasive and abrasive plus chemical wear, respectively. Wear of the diamond tool was measured using the electron beam induced deposition method. This method provides nanometer resolution images of the tool edge (edge radius and wear land) that can be used to calculate volumetric wear loss and wear rates. A method for determining the Archard wear coefficient for diamond turning based on measured wear and cutting forces is also introduced. Comparisons are made between the tool wear resulting from the two materials, and hypotheses related to the wear mechanism are presented.}, number={11-12}, journal={Wear}, publisher={Elsevier BV}, author={Lane, B.M. and Shi, M. and Dow, T.A. and Scattergood, R.}, year={2010}, month={May}, pages={1434–1441} }
