An Arrhenius-type thermochemical wear model proposed by past researchers is evaluated for predicting diamond tool wear when machining low carbon steel. 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...
Quantitative characterization of a diamond tool profile is critical to reveal tool wear mechanisms. 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...
Different rates of wear of diamond tools depend on the physical and chemical nature of the workpiece material. 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...
Vibration-assisted machining (VAM) combines precision machining with small-amplitude tool vibration to improve the fabrication process. It has been applied to a number of processes from turning to drilling to grinding [9,36]. The emphasis on this literature review is the turning process where VAM has been applied to difficult applications such as diamond turning of ferrous and brittle materials, creating...
