  • Modelling and optimization of grinding processes

    01.08.1998· The paper describes different methods for modelling and optimization of grinding processes. First the process and product quality characterizing quantities have to be measured. Afterwards different model types, e.g. physical–empirical basic grinding models as well as empirical process models based on neural networks, fuzzy set theory and standard multiple regression methods


    The grinding machine used in this study was Weldon AGN5 Cylindrical Grinding Machine. The grinding wheel used was vitreous bond CBN. He concluded that, during high speed grinding experiments of both zirconia and M2 steel, normal and tangential forces tend to lessen as the grinding wheel speed increases, but the surface finish is increases.


    The Taguchi method was applied to design the experimental matrix. Four input parameters that were chosen for each experiment were the number of grooves in cylinder surface of grinding wheel, workpiece velocity, feed rate, and cutting depth. Four output parameters that were measured for each experimental were the machining surface roughness, the system vibrations in the three directions (X, Y, Z). The

    The results show that grinding method has insignificant effect on the microstructure and the high hardness value of the completely hardened region at different locations alone the direction of length. The completely hardened region is composed of fine acicular martensites, residual austenites and a little carbides, and the high hardness value is between 760-820HV. As the changing of grinding method, the uniformity and depth of the hardened layer changed accordingly. The quality of grinding

  • Vortex grinding for mechanochemistry: application for

    Abstract. An automated grinding method based on a vortex mixer has been developed. The method enables simultaneous grinding and UV-irradiation, as well as in situ monitoring of solid-state reactivity. The method has been applied to a cocrystallization, supramolecular catalysis, and the preparation of a metal–organic framework.

  • Inventions Special Issue : Modern Grinding Technology

    Standard post-processing methods such as grinding and linishing often meet with major challenges in finishing parts of complex shape. This paper reports on research that demonstrated that mass finishing (MF) processes are able to deliver high-quality surface finishes (Ra and Sa) on AM-generated parts of a relatively complex geometry (both internal features and external facets) under select conditions. Four
