Modeling of the Magnetic Abrasive Machining Process of Flat Surface Workpieces on Numerically Controlled Machine Tools

摘要

The article describes a mathematical model of the circular motion trajectory of a magnetic abrasive powder portion which participates in the magnetic abrasive machining process of flat surface workpieces. The motion trajectory of a magnetic abrasive powder portion is observed. The main formulas, assumptions and recommendations on the implementation of the mathematical model are introduced. Taking into account the feed rate of the machine table, rotational speed and the radius of the cylindrical magnetic inductor, the model allows determining an optimal amount of the magnetic abrasive powder portion which can provide the required efficiency of the finishing process. The magnetic abrasive machining process does not have any fixed standard cutting parameters, so they have to be readjusted every time. The given model can be used to predict the parameters of the finishing process of sophisticated flat surface workpieces.
