“…The increasing surface roughness at increased cutting speeds was attributed to the growing cutting tool nose wear. The impact of cutting speed on surface roughness has been confirmed in the turning of AISI 304 steel [9] and cast duplex stainless steels (ASTM A 995 Grade 4A and ASTM A 995 Grade 5A) [10].…”

The mode of application of cutting liquids in cutting processes determines the properties of the produced surface, workpiece dimensional accuracy, and tool wear, as well as the physical phenomena which occur during cutting. However, their application causes many ecological and social problems connected with environmental pollution and operator health. Their elimination or significant reduction demands a comparable machined surface quality in dry cutting conditions or with a minimized quantity of lubricant. The current paper presents results of research into the cutting process, describing the topographical surface properties obtained in dry and with minimum quantity lubrication (MQL) turning of AISI 316L steel, which have been compared with those obtained after a conventional supply of emulsion. Previous investigations performed on the impact of cutting environment on machined surface quality were usually made in dry or wet conditions. The surface texture was analysed on the basis of the surface roughness parameter Ra, neglecting other important surface features. For this reason surface hybrid roughness profile parameters and the Abbott-Firestone curve as well as the surface topography have been used in the present paper. The experimental results showed a considerable influence of the cutting zone environment and parameters on the cutting force, surface roughness, profile bearing ratio, and the occurrence of surface defects. The presented regression functions allow a calculation and prediction of surface roughness values as a function of cutting zone cooling and lubrication conditions and selected values of cutting parameters in the turning of AISI 316L steel.

“…CPT and CCT of DSS 2205 are well above (40-60 °C) than that of the ASS grades (0-20 °C). Pitting resistance equivalent number (PREN) is high (36) for DSS compared to ASS grades (20). ASS grades can be used in applications where a single property is required, but in places where a combination of properties is required, DSS is the best option [4].…”

Dual-phase structure with 1:1 ratio of austenite and ferrite is termed as "Duplex". Lower cost of duplex stainless steel (DSS) with a combination of good strength and corrosion resistance in a critical environment is captivating many applications. This research work highlights the experimental study of effect of cutting parameters such as cutting speed, feed rate, AlTiN and AlTiCrN-coated tools on response parameters, viz. tool life, surface roughness and cutting forces. Multi-objective optimization using grey relation analysis (GRA) was done to optimize quality response characteristics. High-power impulse magnetron sputtering was used to deposit AlTiN and AlTiCrN coatings on tungsten carbide substrate. Performance measures such as tool life, surface roughness and cutting forces were measured during dry turning of DSS2205 and optimized using Taguchi's GRA technique. AlTiCrN-coated tools exhibited the best results followed by AlTiN-coated tools and uncoated tools. Tool life achieved with AlTiCrN-coated tools is 7 times more than uncoated tools, in which surface roughness was found to be reduced by 67% and cutting forces by 25%. Weighted GRG grade shows that for all the tools used, a cutting speed of 100 m/ min and feed rate of 0.12 mm/rev provided optimum results for response parameters. For change in weightage to response characteristics, different optimum conditions were found for all the tools used. AlTiCrN-coated tool with 100 m/min cutting speed and 0.12 mm/rev feed rate performed better with the highest tool life, the least surface roughness and cutting forces. The results were confirmed by S/N ratio plots.

“…The effects of turning parameters on the surface roughness were investigated by several authors on different materials: duplex stainless steels [1], AISI 304 stainless steel [2], AISI 1050 steel [3], nickel based Hastelloy [4], red brass [5], and aluminum 6061 [6]. These studies included a variety of experimental values of cutting parameters, but all the processes were carried out in dry conditions.…”

This study focuses on the effects of cutting parameters such as cutting speed (Vc), feed rate (f), and depth of cut (d) on roughness induced on the surface of annealed AISI 1020 steel when machined by turning using carbide insert tools. The results indicated that surface roughness increased when feed rate increased and cutting speed decreased. Depth of cut slightly influenced roughness. Analysis of variance and multiple regression techniques were used to formulate a quantitative equation for estimating predicted values of roughness as functions of the cutting parameters. The results showed that cutting speed is the most influencing parameter on surface roughness (69.35%), followed by feed rate (30.13%), while depth of cut failed to affect the responses substantially (0.52%). The proposed model can be used to select the optimum parameters for minimum surface roughness in metal turning.
