Opis:: One of the greatest problems of modern production techniques is the achievement of an appropriate quality at minimal costs and accompanied by the production efficiency increase. Therefore, while designing the production process, the technology used should have a considerable influence on the durability and reliability of machine parts to be produced. During finish treatment, the final dimensions as well as functional properties are imparted to a given element by application of proper treatment type. The engineer has a range of production techniques to choose for the proper surface layer formation. It is crucial to find a suitable solution which will meet the requirements as well as the work conditions of a given machine part. The article presents the results of influence of treatment conditions during turning of shafts on the cutting forces and surface roughness parameter. A roller made of S235JR steel was used for the research. The cutting process was carried out on a universal CDS 6250 BX-1000 and CU500MRD centre lathes. Measurement of cutting forces during lathing process used DKM 2010 and Kistler turning dynamometers. The turning process was conducted by a cutting tool with CCMT09T304 PF removable plate. During the turning, the following machining parameters were used: cutting speed Vc = 150 m/min, feed f=0.106 mm/rev and cutting depth ap = 0.5, 0.75, 1.0, 1.25, 1.5, 1.75 mm. The surface roughness was measured by T8000 profilometer.

Opis:: The paper presents the research results of relationship between surface roughness reduction index KRa and three input parameters: burnishing speed Vn, feed fn and burnishing force Fn., and all combinations of levels of yields N measured for 48 points of experiment. The experiment was repeated 3 times. In order to select the model describing the results of tests, the stepping approximation analysis was performed. It relayed at incorporated into the model in following steps approximation elements function, giving the biggest decrease of the sum of squared deviations. The first approximation was based on the ternary monomial of the powers from 0 to 3 for each input value. This approximation aim was to show, that the index of surface roughness reduction does not depend on the burnishing speed in the made in the area of research. The reduced input parameters to two, i.e. fn and Fn. The plan of the experiment was brought to N = 12 and M = 12. The best approximation of test results obtained in the case of Laurent polynomial with stepping selection of elements. The biggest contribution to the decrease in the sum of squared deviations was element −1 ∙ 3 , and then fn 2. The article shows that in the range fn {0.6:1.2} there was not information on the successful model and the lack of influence of f and Fn on the results of the experiment. It is postulated to retry the experiment for the feed f <0.6.

Opis:: Angular momentum pumps are frequently applied on board ships. As the pumps are working in hard conditions they are made from materials resistant to cavitation wear and electrochemical corrosion. The most popular damage of pump shaft is neck wear in place where seals are mounted. Burnishing, as modern finish plastic tooling method, makes it possible to get high technological quality of elements. The proposed process of burnishing shaft pins is designed to increase the service life of marine seawater pump shaft installations, which should enhance the economic effect. Thanks to its numerous advantages burnishing was proposed to angular momentum pumps shafts tooling instead of finish machining (finish turning, grinding, lapping). The goal was to estimate optimal burnishing parameters which enable receiving biggest strengthening and lowest roughness factor of angular momentum pumps shafts. The tool used was one-roll burnishing tool SRMD type produced by Yamato. The aim of this study was to determine the internat stresses occurring in the subsurface layer after machining carried out, and after burnishing the surface of marine pump shaft pins made of X5CrNH810 stainless steel.

Opis:: The paper presents the research results of the possibilities of applying burnishing as steel finishing treatment for marine pumps shafts. X5CrNil810 (AISI304 L) corrosion resistant steel in the form of a roller 40 mm m diameter was used for the research. The burnishing process was carried out by SRMD single roll burnish by Yamato. During the process of burnishing various parameters of the technological process were used, that is burnishing force, speed and feed. Within the research, the optimization of burnishing technological parameters was conducted on account of the minimalization of Ra coefficient as we 11 as the maximalization of Su. The Slt coefficients values determining the degree of relative hardness of surface layer varied depending on the burnishing parameters applied and fluctuated around l% to 18%. However, the values of KRa coefficients defining the surface roughness reduction index were in the range of l to 15 as a result of burnishing. The object of the paper was to determine the optima! burnishing parameters in order to achieve the highest level of surface layer relative hardness and to decrease the surface roughness of marine pumps shaft pins made of stainless steel. The multi-criteria optimization conducted with the use of min-max method demonstrated that with regard to maximum surface hardness level, burnishing should be carried out at the following parameters of the technological process: burnishing force 1.1 kN, burnishing speed 35 m/min and feed 0.13 mm/rev.

Na statkach bardzo często wykorzystuje się pompy krętne. Ze względu na trudne warunki ich pracy do budowy tego rodzaju pomp stosuje się materiały odporne na zużycie kawitacyjne oraz korozję elektrochemiczną wywołaną przez wodę morską. W przypadku wałów pomp najczęstszą niesprawnością jest zużycie czopów (korozyjne, cierne i zmęczenie stykowe) w miejscu montażu uszczelnień (dławic). Obróbka nagniataniem jako metoda wykańczająca obróbki plastycznej umożliwia uzyskanie elementów maszyn o odpowiedniej jakości technologicznej. W związku z licznymi korzyściami stosowania obróbki nagniataniem proponuje się jej zastosowanie w zamian za wykańczającą obróbkę skrawaniem (toczenie wykańczające, szlifowanie, polerowanie) do wałów okrętowych pomp krętnych. Proces nagniatania przeprowadzono nagniatakiem jednorolkowym SRMD firmy Yamato. Podczas procesu technologicznego zastosowano zoptymalizowane parametry nagniatania, umożliwiające uzyskanie największego stopnia względnego umocnienia warstwy wierzchniej i zmniejszenia chropowatości powierzchni czopów wałów okrętowych pomp krętnych wykonanych ze stali nierdzewnej X5Cr Nil 8 10. Celem pracy było określenie wpływu liczby przejść nagniataka na poprawę twardości i chropowatości czopów wałów pomp okrętowych.

Angular momentum pumps are very often used on ships. Because the pumps are work in hard conditions they are made from erosion wear proof and electrochemical corrosion resistant materials. The most popular damage of pump shaft is neck wear in places where seals are installed. During the technological process, optimum burnishing parameters were applied in order to ensure high degree of surface layer relative hardness and to decrease surface roughness of angular momentum pumps shafts made of stainless steel X5CrNi1810. The objective of the investigation is to determine the effect of burnishing on operating properties, which include: research electrochemical corrosion, friction and fatigue wear pin. The paper will present the results of plastic strain resistance.

Opis:: Angular momentum pumps are applied very often on ships. Because the pumps are working in hard conditions they are made from cavitation wear proof and electrochemical corrosion proof materials. The most popular damage of pump shaft is neck wear in place where seals are mounted. Burnishing as modern finish plastic tooling method makes possible getting high technological quality of elements. Because of many burnishing advantages it was proposed to shafts angular momentum pumps working instead of finish machining (finish turning, grinding, lapping). The goal was to estimate optimal burnishing parameters, which enable to receive biggest strengthening, and lowest roughness factor of angular momentum pumps shafts. The shaft necks are made from stainless steel X5CrNi1810. The tool, one - roller burnishing tool SRMD type produced by Yamato. Its axis is parallel to working shaft axis. During working technological parameters like force, velocity and feed were changed.
Na statkach bardzo często wykorzystuje się pompy krętne. Ze względu na trudne warunki ich pracy do budowy tego rodzaju pomp stosuje się materiały odporne na zużycie kawitacyjne oraz korozję elektrochemiczną wywołaną przez wodę morską. W przypadku wałów pomp najczęstszą niesprawnością jest zużycie czopów (korozyjne, cierne i zmęczenie stykowe) w miejscu montażu uszczelnień (dławic). Obróbka nagniataniem jako nowoczesna metoda wykańczająca obróbki plastycznej umożliwia uzyskanie elementów maszyn o odpowiedniej jakości technologicznej. W związku z licznymi korzyściami stosowania obróbki nagniataniem proponuje się jej zastosowanie w zamian za wykańczającą obróbkę skrawaniem (toczenie wykańczające, szlifowanie, polerowanie) do wałów okrętowych pomp krętnych. Celem pracy było wyznaczenie optymalnych parametrów nagniatania dla uzyskania największego stopienia względnego umocnienia warstwy wierzchniej i zmniejszenia chropowatości powierzchni czopów wałów okrętowych pomp krętnych wykonanych ze stali nierdzewnej X5CrNi1810. Proces nagniatania przeprowadzono nagniatakiem jednorolkowym SRMD firmy Yamato, który charakteryzuje się równoległością osi części roboczej do osi obrabianego czopu. Podczas nagniatania zastosowano zróżnicowane parametry procesu technologicznego takie jak: siła nagniatania, prędkość nagniatania oraz posuw.
