Multiparameter Modeling and Analysis of Mechanical Cutting Process of Grain-Oriented Silicon Steel

Ideally, the process of mechanical cutting of magnetic materials should result in high efficiency, absence of thermal stress, and the ability to shape materials with long cuts. Published models describe control of the mechanical cutting process in terms of the quality of the cut surface. However, there is a lack of data on mechanical cutting of grain-oriented silicon electrical sheets in terms of the quality of the cut surface and the magnetic properties of the workpiece. This letter presents a solution to the gradient optimization problem, combining structural and magnetic analyses. It is shown that it is possible to control the cutting process to obtain high cut surface quality with minimal deterioration of magnetic properties.
