Papers by Keyword: Machine Tool Stiffness

Abstract: this paper discussed the significance of the machine tool stiffness and the definition of the machine tool stiffness classification. This paper studies the stiffness of the machine at home and abroad, the machine rigidity research methods, evaluation and performance optimization design research in recent years are discussed here in the machine tool stiffness, and the problems faced then solutions and suggestions are put forward. Finally, the problem of machine stiffness properties further study and future development trends are summed to improve tools, improve processing quality of products, and reduce production costs.

Abstract: Many models [1-3] have been proposed to study the infeed grinding of Si wafers and to understand its effects on the surface generation. However, most exiting models are based on 2D/3D kinematical analysis of the wheel or its cutting edges, thus unable to suggest the behavior at the interface of wheel/substrate including effects of the elastic deformation and the cutting path density. In this paper, a new grinding model of capable to incorporate the machine tool stiffness and the substrate contact rigidity has been developed. By taking the effect of cutting path density into account, this model is able to give a better explanation of interference between the cutting edge and substrate, and the geometrical profile generated in an infeed grinding scheme.
