AbstractAn analysis of existing technological processes used in the manufacture of parts made of soft magnetic materials establishing a significant impact not only on the magnetic properties, but also qualitative indicators (roughness, microhardness, residual stresses) was made. The influence of technological factors on surface roughness in the processing of 50H permalloy was determined. The mathematical model of the influence of cutting conditions and wear and tear on the roughness value was built. A correlation analysis was made and equations to calculate the altitude and the step roughness parameters were built. These dependencies could be used in the calculation of depreciation, the contact stiffness, fatigue strength. To simplify the usage of the mathematical model in a production environment,
constructed a nomogram, which allows to find the value of roughness depending on the given process.
