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.
