This paper presents the process of a 3-step machining process involving pre-treatment, smoothing and polishing, placing the workpiece in different energy levels of the working load in a rotary-cascade container smoother, by moving it towards the radial direction of the working chamber of the smoother. Studies show the ability to control the course of pre-treatment, smoothing and finishing intensity, both in terms of process parameters and treatment time. Such a structure of the machining process, it also allows you to influence the structure geometry of the machined surfaces in successive stages of machining, and consequently on the final quality. The proposed organization and structure of the process allows for the creation of a new one surface treatment strategy.

The article describes the result of experiments which were intended to compare the results of different workpieces orientation in disc centrifugal machine. During experimental investigations, particular attention was paid to the optimal orientation the workpiece inworking charge. The results of the research presented in this article confirm the benefit of horizontal orientation of the workpiece to the motion of the media in the working charge

The aim of this paper is to answer the question of the distribution of welding distortions. The MIG method was used to make 31 butt welds of 0H18N9 sheet metal, of 6 mm thickness and dimensions 150x350 mm. All joints are made with constant parameters of the welding process. Statistical analysis of the distribution and Kolomogorov-Smirnov test were used in this paper. On the grounds of the analysis it was proved that the distribution of welding deformations is a normal distribution. This justifies the use of experiment planning methods and the use of average values. The relatively high value of the standard deviation makes it necessary to take into account the geometrical parameters of the joint.

Niniejsza praca ma na celu odpowiedź na pytanie, jakim rozkładem opisane są odkształcenia spawalnicze. Metodą MIG wykonano 31 złączy doczołowych z blachy 0H18N9 o grubości 6 mm i wymiarach 150x350 mm. Wszystkie złącza wykonano przy stałych parametrach procesu spawania. W pracy wykorzystano analizę statystyczną rozkładu oraz test Kolomogorowa-Smirnowa. Na podstawie analizy udowodniono, że rozkład odkształceń spawalniczych jest rozkładem normalnym. Uzasadnia to stosowanie metod planowania eksperymentu oraz posługiwania się wartościami średnimi. Stosunkowo duża wartość odchylenia standardowego, stwarza konieczność uwzględnienia parametrów geometrycznych złącza.
