Abstract
The authors describe the method of calculating the magnetic induction in the working gap when
the magnetic-abrasive machining of flat surfaces of workpieces made of ferromagnetic materials
and non-magnetic inductor with permanent magnets. The magnetic system is designed in Ansys
environment, which will be carried out and the calculations presented. The picture shows the field
lines for magnetic-abrasive machining of ferromagnetic and non-magnetic blanks. Also the values
of magnetic induction in the working gap and in the whole magnetic system as a whole when the
magnetic-abrasive machining of ferromagnetic and non-magnetic blanks. In the end, calculations
showed the distribution of magnetic-abrasive powder in the working gap, depending on the material
of the workpiece. For magnetic-abrasive machining of the workpiece of ferromagnetic powder in
the working gap is concentrated under the poles of the inductor. For magnetic-abrasive machining
of the workpiece is non-magnetic powder concentrated under the magnets, and not under the poles
of the inductor.
