| Research Abstract |
It is well recognized that liquid waste disposal in machining process is the one of environment concern during the last decade. In this study, the electric rust preventive machining method was developed with using water as substitution for grinding fluid, and applied for conventional grinding techniques such as cylindrical, surface, internal grinding. The grinding performances were evaluated with respected to grinding force, surface roughness, and surface quality. Further, the storage system based the electric rust preventive machining method was constructed and rust preventive effect was investigated by observation of the workpieces. The obtained results were summarized as follows ;
The electric rust preventive machining method was applied for cylindrical grinding, and investigated grinding performance in comparison with the case of grinding fluid. Rust preventive effect was confirmed with attaching of the skirt type nozzle and the insulation center. The rust preventive machining was possible for 1hour at electric power of 0.21W and the grinding performance exhibited 71.5% against grinding fluid.
The pool electrode which enables workpiece to soak in water was developed for surface grinding. The rust preventive machining became possible for 1hour at electric current of 1.0x10^<-3> and the grinding performance exhibited 88% against grinding fluid. In addition, The pool electrode prevent adhesion of contaminations on workpiece due to consecutive electric current supp electric current supply.
In case of internal grinding, the rust preventive machining became possible for 1hour and the grinding performance exhibited 76% against grinding fluid from the results of grinding force and surface roughness. Moreover, the storage without rust succeeded with using system based the electric rust preventive machining method for 72 hours at the dissipation power of 0.03W
