Part fabricating method and part fabricating apparatus

A part fabricating apparatus comprising:

• an object to be machined holding means for holding an object to be machined in an electrolytic solution;
• a machining electrode for subjecting machining in a surface to be machined of the object to be machined through electrochemical reaction;
• a spacing changing means for detecting and changing a spacing between the surface to be machined of the object to be machined held by the object to be machined holding means and the machining electrode;
• a potential/current control unit for controlling a potential/current on the machining electrode;
• a first electrolytic solution for effecting removal machining on the surface to be machined to fabricate a cast mold;
• a second electrolytic solution for depositing a first metal on a surface of the cast mold to form the first metal layer;
• and
• an electrolytic solution changing means for arbitrary changing a third electrolytic solution for depositing the second metal inside the cast mold to form a part.
