Finite element solution for metal cutting simulation

cutting simulation technology is to study and analyze the physical phenomena in the cutting process, and obtain the cutting force, strain, strain rate, chip, tool temperature and other values in the cutting process through numerical simulation. This is to ensure the stability of process conditions, do research and tool wear research on cutting parameters and tools, and based on cutting force Temperature and other simulation values optimize the NC program. Third wave systems, founded in 1993, is mainly engaged in developing and selling finite element cutting simulation software, which responds to the needs of the processing market. Its product advantedgetm FEM adopts the finite element method to simulate the cutting process; Another product, production moduletm, is good at process analysis and optimizes NC programs based on simulation values such as cutting force and temperature

advantedgetm FEM software

principle and characteristics advantedgetm FEM adopts the finite element method to conduct the physical simulation of the cutting process, and the contents as the input of cutting conditions include: workpiece material characteristics, tool geometry, tool material characteristics, cutting speed, coolant parameters, tool vibration parameters, cutting parameters, etc. After finite element analysis, the software obtains the output results of physical characteristics such as cutting force, chip coiling, chip formation, chip fracture, heat flow, temperature distribution, stress distribution, strain distribution, residual stress distribution on the tool workpiece and chip in the cutting process. Figure 1 shows the cutting simulation and cutting force comparison of three kinds of tools; Figure 2 shows the chip formation and temperature distribution of different cutting parameters

advantedgetm FEM has a rich material library, including 120 kinds of workpiece materials from cast iron to titanium alloy, 100 kinds of tool materials from carbide, diamond to high-speed steel, and tin, tic, Al2O3, TiAlN coating materials; Rich process analysis can be carried out, such as turning, milling (including plunge milling), drilling, boring, broaching, coolant intrusion, spray and other methods. The tool wear simulation mainly adopts the Usui algorithm of Japan; At the same time, it has the parameters of cutting speed, feed rate, rake angle and cutting edge arc radius DOE research; Research on cutting speed, feed rate and DOE of changing tool; It has rich post-processing functions

benefit analysis in the design and development of cutting tools, advantedgetm FEM software can be used to study the coating, shape and material of cutting tools, and recommend cutting parameters for cutting tools. The transformation of the coal-fired furnace of the plastic granulator system has become an important issue to be solved urgently. In the actual cutting process, the best cutting tools and cutting parameters can be selected on the basis of software analysis without copying the recommended cutting conditions provided by the tool factory. Through simulation analysis, improve the removal rate of materials, optimize the cutting force and temperature, chip formation, reduce the distortion and deformation of the workpiece in metal cutting, reduce the residual stress, improve the quality of parts and tool performance, and reduce the test times and costs of on-site trial cutting. Simulation technology helps enterprises improve product quality, extend tool life, improve processing technology, and significantly reduce product manufacturing costs

production moduletm software

principle and characteristics production moduletm software is a process analysis software. Through the comprehensive analysis of workpiece, tool, material data and NC program, the cutting force, temperature and other data in the whole machining process can be obtained. Then, the cutting force, temperature and other parameters in the machining process are optimized by optimizing the feed and cutting speed in the NC program. As shown in Figure 3

after the optimization analysis of production moduletm, the cutting force and temperature in the machining process can be improved, the load balance can be realized, the vibration can be reduced, and the machining cycle can be shortened. The optimized NC program can be processed directly

benefit analysis the databases in production moduletm software are obtained through experiments or advantedgetm analysis. Input the workpiece, workpiece material characteristics, tool parameters, G code/apt code, machine tool control file, and analyze the titanium dioxide process capacity of these parameters, so as to obtain the cutting force, temperature, power and other results in the whole processing process. Then, by automatically optimizing the CNC process 1, ensure the sequence function of the key curve tester on a stable and fixed workbench or horizontal plane, or optimize the parameters of feed and cutting speed, and optimize the cutting force, temperature and processing cycle, so as to improve the production efficiency. The comparison of cutting force and machining cycle before and after NC program optimization is shown in Figure 4

with the continuous development of numerical computing technology, numerical simulation has developed in a multidisciplinary direction, the application of digital simulation technology in various industries has also continued to develop in depth, and the application of product cutting simulation technology in tool design, aerospace and automotive industries has also gradually deepened. In order to meet the needs of domestic enterprises for the application of metal cutting finite element simulation technology and introduce foreign advanced technology, KONE Co., Ltd. has been acting as an agent for the metal cutting simulation software of third wave systems in the United States since 2006, and is committed to providing metal cutting simulation finite element solutions for the domestic manufacturing industry
