“…Cryogenic cooling in machining is categorized into several methods, including pre-cooling the workpiece, cooling the chip, indirect cooling, and jet cooling with ultra-fine nozzles. These techniques aim to harden the material by reducing its temperature, which makes ductile chips brittle and enhances the machining efficiency [16][17][18][19][20][21][22][23][24]. Research has explored the impact of cryogenic temperatures on various materials, including stainless steel, low-carbon steels, high-carbon steel, bearing steel, titanium alloy, and cast aluminum alloy, to understand how they respond to such extreme cooling conditions [25][26][27][28][29][30].…”

Friction between the tool and the workpiece during machining operations always increases the tool wear rate. Removing this problem by using fluids and cooling the tools is essential. In this research, the effects of two cooling conditions: Water Soluble Cutting Oil (WSCO) fluid and R410a coolant, on the tool wear rate, dimensional deviation and surface roughness of AISI 1045 steel (CK45) in turning with a high-speed steel (HSS) tool were investigated. The selected parameters were cutting speeds of 15, 25, 40 and 55 m/min, cutting depths of 0.5, 1 and 1.5 mm and feed rates of 0.05, 0.12 and 0.2 mm/rev. The results show that cooling by R410a coolant reduces the tool wear rate due to its high cooling power and better temperature control at the cutting zone compared to WSCO fluid. Based on the minimums of tool wear, dimensional deviation and surface roughness in different conditions, using R410a coolant can increase the cutting speed by 60% from 25 to 40 m/min. Also, in the optimal condition at a cutting speed of 40 m/min, cutting depth of 1 mm and feed rate of 0.05 mm/rev., tool wear, dimensional deviation and surface roughness are reduced by up to 20, 6 and 10 times respectively. In the optimal condition, the dimensional deviation based on the diameter difference along 300 mm is reduced to 14 µm and also the tool wear rate and surface roughness after 60 min. of turning are reduced to 20 and 3.1 µm respectively. The effect of each input variable on tool wear, dimensional deviation and surface roughness was calculated by statistical analysis and was validated by ANOVA.

Generally, coated cutting tools are preferred in machining of stainless steel. Especially, CVD coated cutting tools come to the forefront owing to its multilayer structure in the industry. In this study, the effects of CVD and PVD coated cutting tools on machinability were investigated in dry turning of 17-4 PH stainless steel. The cutting tools have exactly the same tool geometry. Based on the Taguchi L16 experimental design, experiments were performed for each coating type at different cutting speeds, feed rates and cutting depths. The evaluation parameters were selected as cutting force, surface roughness, tool life and chip formation. The effect ratio of input parameters to output parameters was evaluated with ANOVA and optimum cutting parameters were determined for each coating type with regression analysis. As a result of this study, PVD coated cutting tools showed superior performance than CVD coated cutting tools. It can be said that PVD coated cutting tools are a great alternative to CVD coated cutting tools in machining of 17-4 PH stainless steel.
