Common mining methods in underground metal mines are divided into three categories—namely, the open stope method, the caving method, and the filling method—depending on the methods of excavation and support. Among these, the filling method incurs the highest cost. An applicable method is decided for each mine, largely …

The hierarchical relationship between three broad kinds of grinding models for a spatially homogeneous, linear, time-invariant batch grinding system are first established. Limiting and asymptotic arguments for arriving at approximate but simpler models are employed in all three cases. These parsimonious models provide alternate and, in some respects, …

Kruszynski et al. (1998) found that grinding forces varied greatly during the process of generating gear tooth, and the maximum tangential force was twice the minimum tangential force due to the complex kinematics. Thus, they proposed the models for normal and tangential grinding forces considering the factors including wheel rotation speed and ...

Abstract. Some aspects are considered of the role of control and related 'theory' in mining, mineral and metal processing. The paper should not be regarded as an exhaustive survey of theoretical techniques but rather as an attempt to place in perspective the types of problems which could, at present and in the future, benefit from …

Grinding is one of the essential manufacturing processes for producing brittle or hard materials-based precision parts (e.g., optical lenses). In grinding, a grinding wheel removes the desired amount of material by passing the same area on the workpiece surface multiple times. How the topography of a workpiece surface evolves with these passes is …

Grinding chatter is a kind of self-excited vibration in which the grinding system continuously absorbs energy from the grinding machine, increasing the mechanical energy of the system. Grinding chatter can damage the surface of the workpiece and accelerate the abrasion of the grinding wheel. The theoretical analysis of the grinding …
