Study on Accuracy o f Machined Surface in Electric Discharge Machining (1th Report)

Effect of Advanced Machining and Relationship of Roughness on Base to Side

Abstract

In the present paper, the following experiment and investigation were made. The effet which the advanced machining influence the next machining on Surface roughness, and to clear the relationship of roughness on base to side. The results were as follows.
1) finishing Surface is influence considerably the advanced machining of a work and a tool electrode on surface roughness.
2) There are the roughness limit in advanced machining surface for to obtain the suitable finishing surface, it is important to use the olectrode which have within the roughness of limit.
3) Side surface is generally smoller than base surface in machined roughness, the roughness on both surface may be improved by the Circulating treatment for working fluid.
