“…During service experience, the most common problem that is observed is excessive wear of pins causing their diameter decrease as well as exceeding the permissible shape deviations in place of chokes mounting. Many scientific centres, including Gdynia Maritime University, deal with issues related to the turning surface of the difficult-to-machine [1,2,[4][5][6][7][8][9][10][11][12][13].

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 surface roughness parameter during turning process of stainless steel. A shaft made of 304L stainless steel was used for the research. The chemical composition of steel was measured by Solaris-ccd plus optical spectrometer. The cutting process was carried out on a universal CDS 6250 BX-1000 centre lathes. Measurement of surface roughness was carried out by T8000 profilometer. The turning process was conducted by a cutting tool with Wiper insert. During the turning, the following machining parameters were used: cutting speed Vc [m/min], feed f [mm/rev], cutting depth ap [mm] and additionally changed nose radius r [mm], and tool cutting edge angle ϰr [º]. The results of measurements of Ra parameter underwent statistic analysis. The calculations were conducted by Statistica software.

“…They found that no BUE was formed while machining the work material at a higher speed and low depth of cut. Agustina et al [21] established an experimental analysis to study the effect of cutting parameters and nose radius on cutting forces. In their experiment they machined aluminium alloy (UNS A97075) at dry condition; design of experiment 24 was used to find out the influence of cutting parameters and tool nose radius on the cutting forces.…”

Aluminium (Al) is the suitable material for aerospace and automotive industries due its light weight, corrosion resistance, weldability, non-magnetic and mechanical properties. But, machining of Al and its alloy and finding the suitable tool is really a big challenge because of its formation of BUE (Built-up Edge) and BUL (Built-up Layer). This paper presents the influence of cutting parameters (speed, feed and depth of cut) and its effect on the cutting force and the surface finish. Five different advanced cutting tool inserts (SPUN WC, SPGN WC, PCD, WC ? TiN and WC ? Ti(C, N) TiN ? Al 2 O 3 ) at different cutting speed (V c ) ranging between 300 m/min and 700 m/min and feed rate (f) of 0.045, 0.06, 0.09 and 0.125 mm/rev at a depth of cut of 0.2 mm (constant throughout the experiment) were taken for the experiment. Tool inserts were characterized by Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX) analysis. The cutting forces were measured using Kistler force dynamometer. Amongst all tools, PCD provided a better result in all aspects but surprisingly WC tool provided a better surface finish with lesser tool wear. For all cutting conditions, high speed (670 m/min) and low feed rate (0.045 mm/rev) were recommended. adhana(0123456789().,-volV)FT3 ](0123456789().,-volV)

The cutting force has a significant effect on the geometry and tolerances (e.g. circularity, deviation of circular shape or cylindricity, ovality, conical surfaces) of the workpiece (especially in the case of thin and slim parts), which are key criteria for the products. Moreover, they also affect the tool wear process. Due to the development of technology, the new tool (coatings) and workpiece materials require the exact knowledge of the cutting forces, their investigation during turning is an important field of cutting studies. In the case of turning, the kinetic conditions of which can be seen in Fig. 1, a spatial force system is generated.A new frictional model was constructed by Rusinek et al.[1] in case of orthogonal cutting that took the forces acting on the tool face as well as on the tool flank into consideration. Furthermore, the influence of the tool flank forces on system dynamics was studied.The mathematical modelling of cutting processes can be based on two methods: creating mechanical or phenomenological models. In recent years, several researchers have investigated the machinability of different types of materials, dealt with optimizing, measuring, and calculating cutting forces. The investigation of the machinability of different types of steel is still a basic field of cutting studies.Kulkarni et al.[2] carried out cutting tests on AISI304 austenite stainless steel by using AlTiCrN coated inserts. In their experimental runs, the depth of cut was held at a constant value (a p = 1 mm), the limits of the other cutting parameters were v c = 140 m/min to 320 m/min; f = 0.08 mm to 0.26 mm. The generated forces and the cutting temperature were studied. They said that regarding the force components, the effect of the feed was the most significant; however, the influence of cutting speed was negligible. In contrast, • Novel geometric parameters of the chip cross-section were introduced. Application of a Force Model Adapted for the Precise Turning of Various Metallic Materials• The main values of specific cutting forces characterizing fine turning technology were theoretically calculated.• The applicability of the equations for each material used was investigated by residuals.
