According to an aspect of the disclosed invention, characteristic portions of graphic images to be used for machining in the form of profiles of a plurality of templates are first registered in advance along with machining design data corresponding to the respective profiles of the templates and including machining methods adapted to the respective profiles of the templates in the form of template machinings. Then, a specific characteristic portion is extracted out of the graph image given for a machining operation and the extracted characteristic portion is collated with each of the registered template profiles. Thereafter, the template machinings for the template profile recognized to be corresponding to the extracted characteristic portion as a result of the collation are read out from the registered data. Finally, the related machining design data is assigned to the extracted characteristic portion according to the read out template machinings to automatically prepare a machining program for a punch press.
