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 change of cutting parameters on temperature and cutting forces during turning process of stainless steel. A shaft made of 304L stainless steel was used for the research. The cutting process was carried out on a universal CDS 6250 BX-1000 centre lathes. Measurement of cutting forces during turning process used DKM 2010 turning dynamometer. A cutting tool conducted the turning process with CCET09T302R-MF insert by DIJET. During the turning, the following machining parameters were used: cutting speed Vc = 226 m/min, feed f = 0.044; 0.062; 0.083; 0.106 mm/rev and cutting depth ap = 0.375; 0.625; 0.875 mm.

Jednym z najważniejszych problemów współczesnych technik wytwarzania jest zapewnienie odpowiedniej jakości wyrobu, przy minimalizacji kosztów i jednoczesnym wzroście wydajności produkcji. W związku z tym podczas projektowania procesów wytwarzania powinno się zastosować technologię, która ma istotny wpływ na trwałość i niezawodność części maszyn. Podczas obróbki wykończeniowej nadawane są ostateczne wymiary i właściwości użytkowe danego elementu. Osiąga się to poprzez zastosowanie odpowiedniego rodzaju obróbki oraz dobór właściwych parametrów danego procesu. Technolog projektujący proces kształtowania warstwy wierzchniej ma do dyspozycji różne techniki wytwarzania. Konieczne jest znalezienie określonego rozwiązania, które będzie odpowiadać wymaganiom i warunkom pracy danej części maszyny. W artykule przedstawiono wyniki badań wpływu zmiany kąta przystawienia noża tokarskiego typu Wiper podczas toczenia czopów wału na parametry chropowatości powierzchni.
