With the development of optoelectronics, Non-Rotationally Symmetric Surface (NRS surface) components play a crucial and even decisive role in a series of science and technology fields, such as aerospace, military, medical, communication, which have become an irreplaceable and key parts in photoelectric products. The diamond turning of NRS components through(More)
In this paper an integrated dynamic design and modeling system is developed for aerostatic spindle development. This system integrates initial structural design, bearing stiffness computation and the spindle dynamic performance prediction. Modal fitting is used to transform the finite element model into a two-degree-of-freedom system model, which will make(More)
Large-scale molecular dynamics simulation is performed to study the nano-cutting process of single crystal copper realized by single-point diamond cutting tool in this paper. The centro-symmetry parameter is adopted to characterize the subsurface deformed layers and the distribution and evolution of the subsurface defect structures. Three-dimensional(More)
