(Problem to be Solved by the Invention) The NC device of the conventional wire-cut electrical discharge machining device as described above performs a variety of machining operations, as shown in FIG.
As shown in a) to (d) and FIG. 6, since the items displayed on the screen were fixed, generally necessary items were associated as much as possible and displayed on the same screen.

Also, when displaying coordinate values, they must be displayed larger than other items so that they can be seen from a distance, so the screen used to display coordinate values inevitably has fewer other items. .

However, machining varies widely depending on the user. For example, workpiece offset coordinate values that are necessary for one user may be unnecessary for another user. There was a mix of useful and unnecessary items, making it difficult to see and understand. Furthermore, when a necessary item is not on the screen being displayed, the screen must be changed, which is inconvenient.

This invention was made to solve the above-mentioned problems, and can provide only the necessary items to the user, and
To provide a control device for an industrial machine that allows a user to select, set and display an item that a user wants to see at that time without switching the screen or changing other display items as necessary.
