PROBLEM TO BE SOLVED: To economically mold a full-size model with high precision dimensions so as to secure working accuracy despite deformation of a worked piece by working reaction force of a cutlery in a thin workpiece. SOLUTION: The device is provided with a workpiece fixing part in the shape of open bath, a cold/warm air generating part, and a workpiece supporting and fixing part in the workpiece fixing part. A substance reversibly variable from a fluid to a solid by temperature change is poured into a part recessed by working a single side of worked piece as a fixative member. After the solidification, the substance is closely fixed in the workpiece supporting and fixing part, which enables cutting work at a temperature state at which the fixative member is solidified. By so doing, the fixative member is poured into the workpiece fixing part so as to eliminate temperature change until solidifying the fixative member, which leads to saving of time for solidifying a fixative member.
