Another object of the present invention is to provide an interactive numerical control apparatus which allows an operator who is not familiar with the operation to retrieve and edit desired shape element data in a short time.

[0009]

According to the present invention, in order to solve the above problems, a dialogue program is created in a dialogue numerical control apparatus for creating and editing a machining program based on the shape data and the machining condition data input in the dialogue format. Storage means for storing the shape data and the processing condition data input in the format,
The shape data stored in the storage means and the shape element data forming the shape data are displayed on the field portion of the display screen by the field display means, and processed by the processing program corresponding to the shape data and the processing condition data. Window display means for displaying the subsequent product shape in the window portion of the display screen, and first for specifying the shape element data displayed by the field display means
There is provided an interactive numerical control device, characterized by comprising: a cursor means and a link means for linking a second cursor for specifying the shape element data displayed by the window display means.

[0010]

By using the interactive program input function, the shape data and the processing condition data input by the operator are stored in the storage means.

The shape data stored by the storage means and the shape element data forming the shape data are displayed on the field portion of the display screen by the field display means. Also, the product shape after being processed by the processing program corresponding to the shape data etc. is displayed in the window portion of the display screen by the window display means.

The first cursor for specifying the shape element data displayed by the field display means and the second cursor for specifying the shape element data displayed by the window display means are mutually linked by the link means. It is linked. Therefore, the operator specifies the desired shape element data with one of the first cursor and the second cursor and edits it using the editing function.
