“…Figure 19 is a schematic diagram of the relationship between the main components of the experimental system. Different from other commonly used methods such as pneumatic grinding wheel, chemical mechanical grinding, and so on, 8,29 in this system, the main control computer is the core component, the robot is the actuator, the rotating platform and the blade positioner are the auxiliary parts, and the grinding tool is fitted.

Through numerical calculations, it could be found that when the blade surface quality reaches a certain level, the surface quality of the blade was continuously improved, and the guarantee effect on its performance would be weakened. Under this circumstance, continuing to improve the surface quality of the blade had no positive effect on the performance of the blade. Studies had shown that when the blade surface equivalent grit roughness Ks reaches 4.96 (about R a = 0.8 µm), the blade performance was close to the smooth surface of the blade, and no further processing was required to improve the surface roughness. When the surface equivalent grit Ks was greater than 4.96 µm, the surface roughness had a great influence on the blade performance. When Ks was larger than 40 µm, the negative effect is significantly increased. For the different characteristics of the blade and different processing conditions, four kinds of robot-based blade surface grinding schemes were proposed, of which the core content was the robot layout. Based on the robot group’s fitting to the spatial surface and the path planning, the experimental verification was carried out.

An efficient method for processing superhydrophobic surface is presented in this paper, which can realise the microstructure machining on a large area. First, the microgroove arrays were processed by high speed precision micromilling machine on the surface of the aluminium alloy. Then, the surface of the microgroove was ground by 1000 # electrostatic sand alumina water resistant abrasive belt. The machined surface topography was observed by SEM, which showed that the microgroove arrays were uniform. The contact angles of the water on the microgroove arrays were measured in different directions. In the parallel direction, the contact angle of microgroove arrays is 142¡0?5u, whereas in the vertical direction, it arrives 160¡0?6u. The above values of contact angle mean that a stable superhydrophobic metallic surface was prepared by the micromilling and grinding.

“…To improve the surface quality and processing efficiency, the EDM process must be combined with subsequent finishing technology. 4 Abrasive flow machining is a nontraditional process to improve surface integrity by honing the workpiece surface with a flowing abrasive medium driven by an extrusion piston. It has been found that EDM surface roughness can be effectively reduced with AFM because the recast layer can be removed by hard abrasive particles in the abrasive medium.…”

Abrasive flow machining (AFM) is increasingly preferred to finish closed complicated flow channels machined by electrical discharge machining (EDM) owing to its high machining accessibility, surface integrity, and efficiency. The machining accuracy of closed complicated flow channels by AFM is dependent on the uniformity of material removal distribution (named as finishing nonuniformity here), but few studies on the finishing nonuniformity have been done so far. Firstly the finishing nonuniformity for EDM machined complicated flow channel by AFM was modeled and analyzed theoretically. Then three blisk with EDM surface roughness of Ra 1.5 μm, Ra 2.0 μm, and Ra 3.0 μm were finished by AFM to Ra 0.8 μm, and their finishing nonuniformity was compared. Finally, AFM flow simulation was carried out, and the simulation results were compared with that from the experiments. Theoretical results showed that finishing nonuniformity is resulted from the non-uniform flow field of the abrasive medium, and it increases with increasing EDM surface roughness and decreasing AFM surface roughness. This is verified by the AFM experiments and flow simulations. On this basis, the guideline for parameter optimization in the combined EDM + AFM process was discussed.
