“…The material contains Mo, Ti, Ni, Nb, Cr, and other elements with stable atomic structure, which has a high melting point and high activation energy, resulting in poor relative machinability (Attanasio et al, 2020). As the material of hydraulic parts, aircraft engines, and downhole intelligent tools, it has the characteristics of large cutting deformation, severe work hardening, and low thermal conductivity in deep hole machining (Paturi et al, 2021), which will lead to problems of poor straightness of deep hole and low qualified rate (Ahmed et al, 2019). These parts are expensive.…”

Nickel-based superalloys also have super high strength at high temperatures, which are typically difficult to be processed. As the material of hydraulic parts, aircraft engines, and downhole intelligent tools, it has the characteristics of large cutting deformation, severe work hardening, and low thermal conductivity in deep hole machining, which will lead to the problem of poor straightness of the deep hole. In order to solve the problem of poor straightness of the deep hole in machining nickel-based superalloys, a three-dimensional finite element model of BTA deep hole drilling based on thermal-mechanical coupling is established, and the influence of different blade angles, rotation speeds, and feed rates on drilling force is calculated. The prediction model of drilling force is obtained based on the response surface regression analysis method, and the multi-objective optimization of blade angle, rotation speed, and feed rate are carried out by using the random direction search method. The BTA deep hole drilling experiments are carried out by using the optimized tool and process parameters, and the effects of different process parameters on the straightness of the deep hole of nickel-based superalloys are analyzed. The results of the research show that: Different rotation speeds and feed rates will lead to different degrees of strain hardening and thermal softening. This will lead to a significant difference in the value of the drilling force on the tool. The straightness deviation of the deep hole in nickel-based superalloys can be controlled by optimizing the tool structure and process parameters. The research work in this paper can provide a basis for the structural design of the BTA tool and optimization of process parameters.

Inconel 718 alloy has high strength and generates high temperature during cutting. The impact of chipbreaker dimensions on the cutting temperature when cutting Inconel 718 alloy was investigated. Based on the finite element software Abaqus, a kernel script program is written to develop a cutting simulation plug-in that can quickly change parameters so that users can select tools with different chipbreaker structures, and quickly set tool and cutting parameters to complete a series of pre-processing operations such as modeling, assembly, and meshing. The impact of chipbreaker channel characteristics on the cutting temperature of Inconel 718 alloy is also analyzed by example to verify the effectiveness of the developed plug-in. It provides a convenient tool for subsequent control and optimization of cutting temperature.

“…26 Finite element simulation using Deform-3D software has been used to study the turning process of cutting tools. 27,28 However, for B 4 C-based ceramic cutting tools, this technology has rarely been reported because of the lack of ceramic cutting tool models and related data in the material library of this software. In our previous study, 17 we established a B 4 C-TiB 2 composite ceramic material in the Deform-3D material library, which provides a basis for the further study of B 4 C-TiB 2 -SiC ceramic cutting tools via finite element simulation by Deform-3D software.…”

Here, cutting properties and wear mechanism of the home‐made B4C‐TiB2‐SiC ceramic cutting tools in turning of AISI 4340 steel workpieces were studied through a combination of finite element simulation using Deform‐3D software and turning experiments. Simulation results show that cutting parameters have significant effects on the main cutting force and tool temperature of the B4C‐TiB2‐SiC cutting tool. The optimal cutting parameters for the ceramic cutting tool are cutting speed of 300 m/min, depth of cut of .3 mm, and feed rate of .1 mm/r. Experimental results show the cutting length of the B4C‐TiB2‐SiC cutting tool is about 101 m, which is 21.0% and 32.9% larger than that of the home‐made B4C‐TiB2 ceramic cutting tool and commercially available tungsten carbide tool, indicating that the B4C‐TiB2‐SiC cutting tool has a desired service life. The surface roughness of the workpieces processed by the B4C‐TiB2‐SiC cutting tool is 2.43 µm, which is 29.4% lower than that of the workpieces processed by the B4C‐TiB2 cutting tool, indicating that the B4C‐TiB2‐SiC cutting tool has a satisfying machining accuracy. Wear forms of the B4C‐TiB2‐SiC ceramic cutting tool involve craters, chipping, and flank wear, and the main wear mechanisms are abrasive, adhesive, oxidative, and diffusion wear.
