Wpływ zmiany kąta przystawienia noża tokarskiego typu wiper na wartość parametrów chropowatości powierzchni czopów wykonanych ze stali austenitycznej

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 process 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 research results the influence of changing the side angle of the cutting tool by wiper technology on the value of surface roughness parameters during lathing process. The research was performed on a roller 60 mm in diameter made of X5CrNi18-10 steel. The finish tooling of pump shaft pins was carried out on a universal CDS 6250 BX-1000 centre lathe. In the research of lathing process used inserts with Wiper technology. During the lathing the optimal cutting parameters were used for inserts: CCMT09T302WF, CCMT09T304WF and CCMT09T308WF with nose radius 0,2, 0,4 and 0,8 mm. The cutting process was performed at side angle of 90° ±3°. The process of lathing used cutting tool dynamometer DKM 2010.
