Abstract

PROBLEM TO BE SOLVED: To include an element allowed to be practically used as a reference element for correcting a coordinate system in a coordinate system correction command and to add the command to NC data. SOLUTION: In the case of adding a command for correcting a coordinate system due to a change in the holding of a material to NC data, a tool locus 43 of the material 4 previously prepared on the basis of the NC data is displayed on the screen of a display device 40. When an element 51 is specified in the tool locus 43 displayed on the screen, whether the specified element 51 can be used as a reference element for correcting the coordinate system or not is judged by a correction reference hole judging processing part. When the specified element 51 can be used, a coordinate system correction command generating/adding processing part generates the coordinate system correction command using the specified element 51 as a correcting reference element and adds the command to the NC data.
