Part fabricating method and part fabricating apparatus

摘要

A machining solution for removal-machining an object to be machined 103 is introduced to an inside of a machining solution container 101, and a predetermined voltage is applied to between the machining electrode 104 and the object to be machined 103 to cause electrochemical reaction thereby fabricating a part cast mold. Then the machining solution is changed to a machining solution for metal layer formation to effect additional machining on a surface of the cast mold, forming a metal layer. Then the machining solution is changed to a machining solution for part formation to effect additional machining inside the cast mold, forming a part. Finally the machining solution is changed to a machining solution for dissolving metal layer to dissolve the metal layer to taking out the inside part, fabricating a part.
