“…The high cutting temperature causes the carbide to rapidly wear, so ceramic tools are well suited to machine this alloy at high cutting speed. Some research work has been done to investigate the cutting performance of ceramic tools in machining nickel alloys at high cutting speeds [6][7][8][9][10][11][12][13][14][15][16] . From these studies it can be found that one of the most severe failure modes that controls tool life in machining nickel alloy is the depth-of-cut notch wear (DOC notching).…”

“…Habeeb et al [ 15 ] studied the machinability of nickel-based alloy 242 by using different tool materials under high-speed cutting conditions and found that the main failure mode of the tool is chipping in the high-temperature shear zone. When turning pure nickel, Tan et al [ 16 ] found that a high cutting temperature is the main factor leading to the failure of cutting tools, which can lead to low efficiency in the milling process.…”

Improving the cutting efficiency is the major factor for improving the processing of nickel-based alloys. The novelty of this research is the calibrated SiAlON ceramic tool dry milling nickel-based alloy process. Firstly, the nickel-based alloy dry milling process was analyzed through the finite element method, and the required milling force and temperature were deduced. Then, several dry milling experiments were conducted with the milling temperature, and the milling force was monitored. The change in cutting speeds was from 400 m/min to 700 m/min. Experimental results verified the reduction of the dry milling force hypothesized by the simulation. The experiment also indicated that with a cut depth of 0.3 mm, cut width of 6 mm, and feed per tooth of 0.03 mm/z, when milling speed exceeded 527.52 m/min, the milling force began to decrease, and the milling temperature exceeded the nickel-based alloy softening temperature. This indicated that easy cutting could be realized under high-speed dry milling conditions. The interpolation curve about average temperature and average milling forces showed similarity to the tensile strength reduction with the rise of temperature.

“…This superalloy is a hard-to-cut material in machining for the following reasons. (1)(2)(3)(4)(5)(6) (1) Work hardenability: boundary chipping and edge wear of the cutting clearance increase over time, the cuttings are tough and difficult to break off, and case hardening occurs. (7,8) (2) Low thermal conductivity: although general steel can generate cutting heat when being cut, most of the heat is carried away by the cuttings; however, as Waspaloy has low thermal conductivity, it readily accumulates the cutting heat of the tool and machined part; moreover, it has high yielding point, tensile strength, and cutting resistance, making it easy for the cutting edge to induce high pressure and temperature, and plastic deformation of the tool.…”

Nickel-based materials are widely used in engines, housings, and compressor rotors. They are also used in other industries, such as energy, petrochemicals, and tool and die making. Nickel-based alloys have a high tolerance to high temperatures and superior anti-corrosion characteristics while maintaining good mechanical properties. Owing to the development of precision casting technology in the late 1950s, a series of highly intensive cast nickel-based superalloys with these properties have been developed. With the rapid changes in the military and civil space industries in recent years, the use of nickel-based superalloys is increasing. In this study, we mainly use Waspaloy as a nickel-based material to study cutting; we use regression analysis to find the significant factors affecting cutting force and surface accuracy and then perform an optimization experiment. A TiAlN-coated tool is mainly used in the study of cutting. We conclude that the significant factors affecting the cutting force among the experimental conditions are the cutting depth and feed rate per tooth and that the significant factors affecting the surface accuracy are the feed rate per tooth and cutting speed. When the cutting depth dp increases from 0.1 to 0.3 mm, the tool wear increases by 94.1%, and when the cutting speed V c increases from 30 to 40 m/min, the tool wear decreases by 2.17%. 1. Tool form: R200-024A32-16M. 2. Machining parameters: cutting speed V c = 40 mm/min; cutting depth dp = 0.3 mm.
