With the improvement of assembly performance of platen workpiece, the roughness of outer circle of platen workpiece is required to be Ra 0.4. As the workpiece is turned on a CNC vertical lathe, the original level is about the surface roughness Ra 0.8 to Ra 1.3, which cannot meet the performance requirements. In this paper, the outer circle polishing device is developed, which is installed on the cutter tower of the finishing outer circle machine tool. After finishing the outer circle, it directly polishes the outer circle to the roughness of Ra 0.4.The workpiece after using the device structure can fully meet the accuracy requirements.

“…[18][19][20][21] Discrete phase model was used in ANSYS Fluent to analyze the wall shear, drag force and turbulent intensity generated at the inner and outer nozzle surface and it was found that the trajectories of velocity and pressure had a great influence on the outcomes by taking pressure, velocity, SOD, grain size and abrasive flow rate in AJM. 22,23 Zirconia titanate and aluminum nitride were used as target material to investigate the erosion rate by taking different simulating parameters i.e., pressure, mass flow rate of jet, jet impact angle and found that maximum erosion took place at 90 degrees of impingement angle in ASJMM 24 and AJM 25,26 using ANSYS Fluent. Wall shear stress was generated by the injected pressure and velocity at the workpiece surface in AJM.…”

The proposed research work accomplishes the experimental study and computational fluid dynamics (CFD) technique for erosive footprint prediction extent in hot abrasive jet machining (HAJMing) constraints on target surface erosion rate, surface roughness of intricately shaped tapered holes generation. The CFD-obtained footprints were in superior agreement with experimentally measured data. HAJMing process uses a relatively high speed air-hot abrasive stream to produce both high accuracy micro-channels and tapered holes. HAJM also defines itself phenomenal competence over all advanced manufacturing techniques due to its growing demands for better surface reliability with defects (mostly stress, heat) free surfaces. Zirconia is widely accepted and associated in the non-conventional machining processes and industries with the years of track on record of proven performance in a vast number of brittle materials. Most perceptible act in this research is the selection of abrasive particle to achieve the appropriate intricate shaped holes on zirconia ceramic with hot silicon carbide (SiC) abrasives. Machining of these features are done with varying the abrasive temperature. Optical microscopic view was considered for the generation of machined holes during HAJMing. All the experimental data were presented to study the effect of machining constraints on target surface erosion rate and surface roughness using HAJMing. Single impact experiments were executed to measure the target surface erosion due to impact of individual hot silicon carbide abrasive particles. An experimental setup has been designed to conduct the machining trials using Box-Behnken design of experiments. It is also shown that the generated workpiece surface contour and erosion rate are the function of machining constraints which have a negligible influence on air-abrasive flow characteristics. This research work also deals with the sustainability assessment under environmental-friendly hot abrasive-assisted machining conditions.
