Automatic programming apparatus and automatic programming method

An automatic programming apparatus that generates control command data, based on processed unit data for partial processing to apply partial processing to a material shape, comprising:

• a material shape data input unit that receives an input of data of the material shape;
• a processing program storage unit that stores therein the data of the material shape and processed unit data;
• a processed unit data input part that receives an input of other-processed-unit-reference-type processed unit data referencing processed region shape data contained in the processed unit data stored in the processing program storage unit and that outputs the other-processed-unit-reference-type processed unit data to the processing program storage unit;
• a processed region shape generating unit that generates processed region shape data in the processed unit data for the partial processing, based on the data of the material shape and the processed region shape data referenced by the other-processed-unit-reference-type processed unit data;
• and
• a control command generating unit that generates the control command data, based on the processed unit data for the partial processing containing the processed region shape data.
