Worn Tool Forces Based on Ploughing Stresses
Recent work in modeling of the ploughing mechanism in basic metal machining may provide a means of estimating the additional forces to be expected when cutting with a worn tool. The results predict the rubbing stresses due to the finite radius of an unworn tool edge. Since an unworn tool can be thought of as a worn tool with a wear land width VB = 0, these stresses can make up part of a strateg...
متن کاملAn Analytical-thermal Modeling Approach for Predicting Forces, Stresses and Temperatures in Machining with Worn Tools
In this paper, predictive modeling of cutting and ploughing forces, stress distributions on tool faces and temperature distributions in the presence of tool flank wear are presented. The analytical and thermal modeling of orthogonal cutting that is introduced in Karpat, Zeren and Özel [3] extended for worn tool case in order to study the effect of flank wear on the predictions. Work material co...
متن کاملA Worn-Out Welcome
A 298 W hen Iceland became the first country to ban most forms of asbestos in 1983, 1 global use hovered around 4.3–4.7 million metric tons per year. 2 Twenty-five years later, with several dozen countries now implementing some form of ban, 1 that number had dropped to 2.1 million metric tons. 3 Today, while demand has plummeted in most developed countries, it continues to rise in those countri...
متن کاملExemplar-based Worn Edges
To counteract the sterile look of computer-generated worlds, we introduce a procedural model for worn edges that can be seen in buildings and stones: edges that have suffered minor damage at multiple points, resulting in material being chipped off. Employing data gathered from photographs, the method adds minute detail along exposed edges. The deformed geometry may be simulated with normal maps...
متن کاملFracture susceptibility of worn teeth.
An experimental simulation study is made to determine the effects of occlusal wear on the capacity of teeth to resist fracture. Tests are carried out on model dome structures, using glass shells to represent enamel and epoxy filler to represent dentin. The top of the domes are ground and polished to produce flat surfaces of prescribed depths relative to shell thickness. The worn surfaces are th...
