Abstract Although Inconel 718 is an important material for modern aircraft and aerospace, it is a kind material, which is known to have low machinability. Especially, while these types of materials are machined, high cutting temperatures, BUE on cutting tool, high cutting forces and work hardening occur. Therefore, in recent years, instead of producing new cutting tools that can withstand these difficult conditions, cryogenic process, which is a heat treatment method to increase the wear resistance and hardness of the cutting tool, has been applied. In this experimental study, feed force, surface roughness, vibration, cutting tool wear, hardness and abrasive wear values that occurred as a result of milling of Inconel 718 material by means of cryogenically treated and untreated cutting tools were investigated. Three different cutting speeds (35-45-55 m/min) and three different feed rates (0.02-0.03-0.04 mm/tooth) at constant depth of cut (0.2 mm) were used as cutting parameters in the experiments. As a result of the experiments, lower feed forces, surface roughness, vibration and cutting tool wear were obtained with cryogenically treated cutting tools. As the feed rate and cutting speed were increased, it was seen that surface roughness, vibration and feed force values increased. At the end of the experiments, it was established that there was a significant relation between vibration and surface roughness. However, there appeared an inverse proportion between abrasive wear and hardness values. While BUE did not occur during cryogenically treated cutting tools, it was observed that BUE occurred in cutting tools which were not cryogenically treated.

Stainless steels with unique corrosion resistance are used in applications with a wide range of fields, especially in the medical, food, and chemical sectors, to maritime and nuclear power plants. The low heat conduction coefficient and the high mechanical properties make the workability of stainless steel materials difficult and cause these materials to be in the class of hard-to-process materials. In this study, suitable cutting tools and cutting parameters were determined by the Taguchi method taking surface roughness and cutting tool wear into milling of Custom 450 martensitic stainless steel. Four different carbide cutting tools, with 40, 80, 120, and 160 m/min cutting speeds and 0.05, 0.1, 0.15, and 0.2 mm/rev feed rates, were selected as cutting parameters for the experiments. Surface roughness values and cutting tool wear amount were determined as a result of the empirical studies. ANOVA was performed to determine the significance levels of the cutting parameters on the measured values. According to ANOVA, while the most effective cutting parameter on surface roughness was the feed rate (% 50.38), the cutting speed (% 81.15) for tool wear was calculated.

Cutting Tool Wear

As the main method of high efficiency cutting Ni-based superalloy, high-speed cutting can not but intensify the cutting-tool wear for the high cutting force and cutting temperature. So, it is very necessary to study the process of cutting-tool wear and wear mechanism, especially, the effect of cutting-tool wear on the cutting force, cutting temperature and surface roughness of machined workpiece. In this paper, investigation of tool wear in high-speed cutting is proposed, the PCDTiAlN carbide insert is used in the experiment, the cutting-tool wear and the corresponding cutting force, cutting temperature and surface roughness of machined workpiece is detected. It indicates that the cutting force, cutting temperature and surface roughness of machined workpiece is changed corresponding the cutting-tool wear,the wear process of coated tool include the coated material wears and base material wears,the wear mechanism is complex.

Cutting Tool Wear

As the main method of high efficiency machining Ni-based superalloy, high-speed cutting can not but intensify the cutting-tool wear. So, it is very necessary to find the rule of cutting-tool wear in high-speed cutting superalloy, especially, the effect of cutting-tool wear on the cutting force, cutting temperature and surface roughness of machined workpiece. In this paper, the PCDTiAlN cemented carbide insert is used in the experiment, the value of cutting-tool wear and the corresponding cutting force, cutting temperature and surface roughness of machined workpiece is measured. It indicates that the cutting force, cutting temperature and surface roughness of machined workpiece is changed corresponding the cutting-tool wear changes, and cutting-tool is serious, for example, the crater wear expands quickly; the boundary wear is obvious.
