LOGISTICS OF EXPERIMENTING WITH STRENGTHENING THE SURFACE LAYERS OF MACHINE PARTS

Abstract

The authors within the scientific contribution present the logistics of laboratory experimenting with strengthening the stressed surface layers of machine parts. The project for strengthening the surface layers was conducted without the use of ultrasonic strengthening via the newly developed device with a static pressing force. Emphasis was placed on the stage of identification of samples surface layers, their microstructure, roughness and hardness after lathe turning and shot peening as well as on the wear of the used forming element after shot peening. The process of experiment results in the modelling of technological conditions and parameters of a newly-designed and verified technology with formulating the logistics steps for practical use. Logistics can be seen, in addition to a structured arrangement of relationships and activities, as a control system process able to efficiently use available resources in terms of time and value within the various activities at the lowest costs incurred.
