Поверхностная деформация и наклеп при обработке стальных заготовок иглофрезированием

Abstract

The executed researches allowed determining the main consistent patterns of formation and hardening of details at discrete contact with the tool. The revealed regularities, formations of properties of a blanket of a material of details of cars, allowed carrying out optimization and management of the specified process of processing for providing demanded operational characteristics of details of cars. It is established that technological heredity has impact on change of parameters of quality. At certain modes of process of an needle milling there is not a cutting micro- and macroroughnesses on a processed detail, and their crumbling, burnishing, in other words – process of cold plastic deformation which in turn leads to srface hardening, or a mechanical hardening. Results of the solution of a compromise task allow providing at the expense of a combination of technology factors of an needle milling the maximum productivity with a set height of microroughnesses of surface and macroroughness with a set depth of the strengthened layer
