“…Before analyzing the damage mechanism of cemented carbide tool, the initial and critical damage values of tool material must be determined, which represents the damage state of the tool in the initial state and the limit state [30]. According to the existing researches, it can be known that the initial and the critical damage values are the inherent properties of tool material, in other words, these two values are independent of all external conditions.…”

Aiming at the breakage of tool and low precision of the machined surface in the high-speed milling process of titanium alloy, damage mechanics is used to reveal the formation mechanism of tool fatigue breakage during the milling and determine the critical condition of tool breakage. Cutting edge chipping caused by random impact fracture during the evolution of tool damage is the main failure form of tool fatigue breakage. Based on continuous damage mechanics, fatigue crack growth theory and sliding crack energy balance equation, the crack growth law of tool material is studied under different cutting impact, and the initial damage value and critical damage value of tool material fracture based on the interval method are obtained. And the impact fracture limit conditions of the end mill edge are established including cutting parameters, material hardness, tool damage, tool wear, and cutting impact, which provide a theoretical basis for determining the cutting parameters. A titanium alloy milling experiment is carried out to define the impact damage morphology of the tool in different states after the tool is damaged. The obtained tool safety area range is verified, and the research results provide parameter optimization for the high-speed and high-efficiency milling titanium alloy process.

“…Cui et al, computationally and analytically investigated the impact of feed rate and depth of cut on cutting temperature in face milling and identified that heat flux reduces as the tool-chip contact area increase by increasing the uncut chip thickness [37]. Karaguzel et al developed a model for cutting temperature in face milling using Green's function and assuming that all the energy used for cutting is transformed into heat at the cutting zone [38].…”

“…In the analytical prediction of cutting temperature, Aneiro et al [22] conducted experiments on hardened steel with multilayer coated carbide tools and studied the influencing factors of tool temperature, tool wear, cutting force, and surface roughness. Under conditions of fixed cutting speed and metal removal rate, Cui et al [23] studied dependencies of the average instantaneous temperature of the tool on the radial depth of cut and the feed rate when the AISI H13 tool steel was face-milled with an uncoated cemented carbide tool. Zhou [24] proposed an analytical model for predicting workpiece temperature in a torus end mill with 4-axis milling and verified the validity of the model.…”

Excessively high temperature during milling will shorten the life of the milling tools, reduce the surface quality of the workpiece, and increase production costs. In this paper, a novel cutting temperature prediction model for milling Al7050 is proposed, which considers both tool geometry parameters and milling parameters. The aim is to adjust the milling conditions in advance according to the predicted temperature, thereby prolonging the tool life and improving the machining quality. Through single-factor experiments, it is found that there is a polynomial relationship between tool geometric parameters and cutting temperature. Based on the empirical formula of cutting temperature, an improved mathematical model of cutting temperature is proposed. In this model, eight variables including tool geometry parameters and milling parameters are considered. The coefficients of the mathematical model are determined by the cyclic fitting method. The simulation data and experimental data show that compared with the temperature prediction model considering only milling parameters, this model has better prediction accuracy. This idea can also be used to establish the cutting temperature prediction model of other materials.
