Formation of quality indicators for flat surfaces of machine parts when running them with a reinforcing roller

Abstract

The forming of parameters of quality of parts flat surfaces during their rolling by strengthening roller is studied and it is shown that for each value of rolling force there are extremely achievable indicators of quality of the surface layer. It has been established that the spread of quality indicators values on the strengthened surface of the part is stabilized and becomes minimal after three passes of the roller. The functional dependence of the roughness parameter value of the part flat surface on it’s previous value and rolling mode is obtained, which allows solving a number of technological problem.
