| Research Abstract |
In order to put "Super-precision machining using of activate surface phenomenon on the very small electric field" to practical use, following two stage research has been carried out.
(1)Condition optimization of super-precision machining using of activate surface phenomenon on the very small electric field The phenomena in grinding machining are interacted by the tool condition, workpiece condition, relative movement condition, interference condition between workpiece and wheel, machining condition and cooling condition. In the case of super-precision grinding machining using of activate surface phenomenon on the very small electric field, the phenomena are interacted by the intensity of very small electric field and the maximum of cutting depth. Then in this approach the condition optimization of super-precision machining using of activate surface phenomenon on the very small electric field are searched by the objectively evaluation of surface roughness, machining accuracy of workpiece and alteration layer of workpiece.
(2) Experimental and theoretical research of super-precision machining using of activate surface phenomenon on the very small electric field
From the research results the grinding surface of the super-precision machining using of activate surface phenomenon on the very small electric field are generated by the huge group of cutting grooves, but the depth are constant by the intensity of very small electric field, so on the surface finish of workpiece is carried out as good condition.
