When applied to blisk blade profile polishing of aero-engines, “five-axis NC + flexible grinding head + elastic grindstone” polishing technological equipment has advantages of high precision, minor interference, favorable adaptivity, etc. In order to improve the polishing quality and polishing efficiency, a mathematical calculation formula of polishing efficiency was established according to the polishing principles of elastic grindstone (sanding wheel). The optimized combination of technological parameters ( ω = 6000 r/min, ap = 0.9 mm, vf = 320 mm/min) was obtained through the range method of orthogonal test results with double optimization objectives—surface roughness and polishing efficiency. Based on the relationship between number of polishing times and surface roughness, a technological program was put forward, that is, polishing is firstly conducted using 320# sanding wheel for 6 times and then 400# sanding wheel for 9 times (totally 15 times) under the optimized combination of technological parameters, then surface roughness less 0.4 μm can be achieved. Blade polishing test results indicate that: efficiency-optimized technological parameters can not only significantly shorten polishing time but also acquire qualified blade surface roughness less 0.4 μm, thus verifying reliability of the optimization method and results.

“…Its overall performance largely depends on the processing quality of the blades [1], therefore, the manufacture of blades with high geometric precision and good surface quality is the key link in the manufacture of advanced aircraft engines. At present, the use of a multi-axis linkage milling process in China has been enough to fulfill the processing requirements of the whole blisk blade [2]. However, because the overall blade milled is a freeform surface in space, and the surface has a significant milling residual height and the resulting peaks and troughs [3], the surface roughness is large.…”

As for the efficient and high-precision grinding of blades, it was studied that a flexible grinding path planning method of the abrasive cloth wheel of the blades. In the paper, based on modified Preston equation, the radial material removal depth model is supplemented, which provides theoretical support for the establishment of the flexible grinding path of the abrasive cloth wheel. After obtaining the abrasive cloth wheel envelope surface by the double parameter sphere family method, the deformation amount of the abrasive cloth wheel is used as the directed distance from the point of the designed surface to the envelope. The sequential linear optimization algorithm is used to optimize the directed distance. Then, the flexible grinding path for constant material removal is obtained. The results of the simulation show that the profile error of the blade processing is improved under the requirements of surface roughness.

“…However, due to their complex curvature and poor rigidity, LTE areas are also the most di cult areas to machine. Researchers have conducted studies from the perspective of contact force control [19], process parameter adjustment [20], and trajectory parameter optimization [21,22] to improve LTE machining accuracy. However, the in uence of tool-path planning on the machining of the LTEs of blades is rarely discussed.…”

Planning tool-paths on free-form surfaces is a widely discussed issue. However, traditional methods of generating paths capable of meeting all the requirements of blade machining remain challenging. In this study, a new iso-parametric path-planning strategy based on a novel parameterization method combined with the conformal transformation theory was proposed. The proposed method could adapt to the curvature characteristics of the blade surface, improving the kinematic performance of the machining process, reducing multi-axis coordinated motion control complexity, and improving machining quality. The proposed method was then compared with three traditional methods. The influence of the tool-path on the kinematic performance of the machine tool was quantitatively examined based on the kinematics models of two different machine tools. A large cutting depth milling experiment was conducted to verify that kinematics optimization could improve machining quality. The proposed method provides a more reasonable path-planning approach for blade machining on a five-axis machine tool, which is of great significance in reducing the cost of blade machining and the risks of blade failure. Moreover, it is of great significance for the large-scale automated production of blades.
