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.

In order to study the influence of double-slotted cutter on chip forming, this paper uses the general finite element simulation software ABAQUS, and builds a finite element model based on Johson-cook material model and Johson-cook fracture criterion. This paper analyzes the changes in cutting force and cutting temperature obtained when cutting titanium alloys with three different double-slot structures. This paper draws the cutting force and cutting temperature change curve at the tool tip, and analyzes and compares the post-processing results of the three geometries. The test results show that the double concave arc groove cutter has less cutting force and cutting temperature during cutting, and the cutting process is relatively stable, which is more suitable for cutting than other groove types.
