  • "Modeling and simulation of grinding processes based on a

    Grinding is a complex material removal process with a large number of parameters influencing each other. In the process the grinding wheel surface contacts the workpiece at high speed and under high pressure. The complexity of the process lies in the multiple microscopic interaction modes in the wheel-workpiece contact zone including cutting plowing sliding chip/workpiece friction chip

  • Dynamic Modeling and Simulation of SAG Mill Circuits with

    Grinding is one of the most energy-consuming processes in the mining industry. As a critical part of the comminution process autogenous grinding (AG) or semi-autogenous grinding (SAG) mills are often used for primary grinding. However the breakage mechanism of an AG/SAG mill is inefficient in grinding particles of a certain size typically in the range of 25-55 mm i.e. pebbles.

    In this work we focus on the computational bridging between the meso- and macro-scale in the context of the hybrid modelling of Internal Traverse Grinding with electro-plated cBN wheels. This grinding process satisfies the manufacturing industry demands for a high rate of material removal along with a high surface quality while minimising the number of manufacturing processes invoked.
