Abstract

La présente invention concerne un dispositif de commande de valeur numérique (1a) qui est caractérisé en ce qu'il est pourvu : d'une unité d'affichage de systèmes de coordonnées (11a) affichant une pluralité de systèmes de coordonnées qui servent de références pour des instructions d'opération ; et d'une unité d'affichage de relation (12a) qui, lorsque les systèmes de coordonnées comprennent un premier système de coordonnées et un second système de coordonnées défini sur la base du premier système de coordonnées, affiche des informations de relation indiquant que le second système de coordonnées est défini en utilisant le premier système de coordonnées comme référence, sur un écran sur lequel les systèmes de coordonnées sont affichés.
