A Study on Development of Spin-Casting Process with CNC Machining

CNC 머시닝을 이용한 Spin-Casting 공정개발에 관한 연구

Spin casting is one of useful methods to manufacture metal parts with low mold cost and short delivery time. But the silicon rubber based conventional method has several problems such as poor dimensional accuracy, limitation in casting materials and its dependency on speciality in meld making process. To solve those problems, this paper suggests a steel based mold making method using direct CNC machining and the experimental results shows that the parts from the developed method has better dimensional accuracy and surface roughness than those from the conventional method.
