Effects of Working Conditions on Deformed Layer of STD11 in Wire-cut EDM
Abstract
본 연구에는 열처리된 금형강(STD11)을 사용하여 가공조건으로 가공전류, 와이어장력, 이송속도 등을 변화시켜 변질층 깊이와 경도를 현미경 조직사진을 통한 조직변화의 고찰과 경도시험을 하여 검토하였다. 그 결과 다음과 같은 결론을 얻었다. (1) 변질층의 경도는 가공전류 3A, 와이어장력 1500gf 및 이송속도 80%일 때 Hv685(HRC59.5)로 가장 높았다. (2) 변질층의 깊이는 가공전류 3A이며 와이어장렬 1500gf이고, 이송속도 80%일 때 약 6㎛로서 가장 낮았다.
In this study, deformed layer thickness, hardness and microstrucre of deformed layer were investigated with the variations of peak current, wire tension and feed rate, and the material is heat-treated STD11.

The results have shown that (1) deformed layer thickness is minimum at 3A, 1500gf, and 80% and (2) hardness is the highest at peak current 3A, wire tension 1500gf and feed rate 80%.
