To solve the problems of low efficiency, poor surface quality, and short tool life in the milling of titanium alloys, this study took the micro-textured ball-end milling tool as a starting point and established a platform for friction and wear tests. Based on a new method of external friction theory, the anti-friction and anti-wear mechanisms of the micro-textured tool were analyzed. According to these mechanisms, the optimal area proportion of the micro textures in the contact area between the chip and tool was theoretically investigated considering the milling force, and the proportion was verified experimentally. This work provides a reference for improving the cutting performance of hard metal tools.

“…An inappropriate selection of micro-texture parameters can accelerate the wear on the rake face and the likelihood of the cutting edge breaking. In this study, drawing upon prior research [15], the micro-pit diameter ranged between 30 and 60 µm, the depth was between 40 and 70 µm, the spacing was between 125 and 200 µm, and the distance from the cutting edge was between 90 and 120 µm. The representative meaning of each parameter is shown in Figure 4.…”

When machining titanium alloy parts, aside from accuracy, the other key concern when evaluating their quality is the integrity of the machined surface. Residual stress can have a significant impact upon this. A certain amount of residual stress can help to strengthen the workpiece, but excessive residual stress can lead to its deformation. In this paper, we report on an experimental study of the surface integrity of titanium alloy after milling with a microtextured ball-end cutter. Tests were conducted to assess the residual stresses on the surface of titanium alloy workpieces according to the direction of feed and milling. The impact of different micro-texture parameters was also assessed; namely, the diameter, depth, spacing and distance from the cutting edge of the individual pits. Range analysis, which is an orthogonal test, was used to analyze the results of the experiments and a prediction model of surface residual stress was established for the milling of titanium alloy with micro-textured ball-end cutters. This model can provide theoretical support for the optimization of the parameters involved in future milling processes.

“…Analytic hierarchy process (AHP) is a decision analysis method to solve complex multi-objective problems, which can combine the qualitative problem with the quantitative problem [15][16][17]. The hierarchical structure model of process parameters can be divided into three levels: target layer, rule layer and schematic layer.…”

There are many process parameters involved in the deep drawing of TWBs. Each parameter has different effects on the forming quality and intercrosses each other. It is difficult to establish the relationship between the process parameters and forming quality in traditional methods. The TWBs square box part of the same material with different thickness was taking as the research object, and the common defects of the deep drawing forming part was analysed. The forming process was simulated by using finite element software DYNAFORM, considering five factors, including the thickness combination, the friction coefficient, the punch and die corner radius, the three types of variable blank holder force loading method, as well as the intercross between the variable blank holder force loading method and other factors on the forming quality of the TWBs square box part. The orthogonal test was designed to determine the important order of the various factors under different indicators, and the optimal combination of process parameters was determined by combining the AHP and grey system theory. The optimized parameters of square box part were verified by the finite element method and the deep-drawing test. The results show that the thickness distribution is reasonable, the welding seam movement is small, and there is obvious improvement in the forming quality.
