Article Preview

A multi-scale model is proposed to explain the effect of material induced vibration and the quantitative relation between cutting force and the surface quality from dislocations, grain orientations, cutting tools, machine tools used in the simulation of the nano-3D surface topology in single-point diamond turning. The model-based simulation system composes of several model elements which include a microplasticity model, a dynamic model and an enhanced surface topography model. The multi-scale model brings together knowledge from various disciplines to link up physical phenomenon occurring at different length scales to explain successfully the surface generation in single-point diamond turning of crystalline materials, and offers a new direction of research in ultra-precision machining.
