Color display method for NC system having automatic programming function

Claim 2

A color display method for an NC system having an automatic programming function and equipped with an automatic programming unit for administering automatic programming, an NC unit for administering numerical control, an operator's panel and a color display device provided for common use by both the automatic programming unit and NC unit, and a control unit which causes the operator's panel and the color display device to operate on behalf of the one of the NC unit and automatic programming unit which corresponds to a selected mode, based on selection information, entered from a selection key provided on the operator's panel, for selecting an automatic programming mode or an NC mode, comprising the steps of: (a) storing beforehand a correlation between a display item and a display color in the NC mode; (b) informing the NC unit, via the control unit, of the name of an item for which display has been requested when a predetermined item display request key provided on the operator's panel is pressed while in the NC mode; and (c) applying color information, which corresponds to the item for which display has been requested, to the color display device, so that the color display device displays the requested item in color.

Claim 3

A color display method for an NC system according to claim 1, wherein said step (a) comprises storing the correlation in a memory incorporated within the control unit.

Claim 4

A color display method for an NC system according to claim 1, wherein said step (c) comprises applying item data corresponding to the name of the item, from the NC unit to the color display device.

Claim 5

A color display method for an NC system according to claim 3, wherein said step (c) further comprises providing the color display device with frame memories for red, blue and green, storing an item image, based on the item data, in a predetermined one of the frame memories designated by the color information, and scanning the frame memory to display the item data in color.

Claim 6

A color display method for an NC system for performing an automatic programming function during an automatic programming mode and having an NC unit for performing a numerical control function during an NC mode, comprising the steps of: (a) storing a predetermined correlation between items to be displayed and corresponding colors with which the items are to be displayed during the NC mode of operation; (b) automatically informing the NC unit of the name of an item for which display has been requested when an operator selects an item for display; (c) automatically supplying color information corresponding to the item for which display has been requested, to a color display device; (d) providing item data corresponding to the item to be displayed, from the NC unit to the color display device; and (e) displaying the requested item in color on the color display device based on the color information supplied in said step (c) and the item data provided in said step (d).

Claim 7

A color display method for an NC system for performing an automatic programming function during an automatic programming mode and having an NC unit for performing a numerical control function during an NC mode, comprising the steps of: (a) storing a predetermined correlation between items to be displayed and corresponding colors with which the items are to be displayed during the NC mode of operation; (b) automatically informing the NC unit of the name of an item for which display has been requested when an operator selects an item for display; (c) automatically supplying color information corresponding to the item for which display has been requested, to a color display device; (d) providing item data corresponding to the item to be displayed, from the NC unit to the color display device; and (e) displaying the requested item in color on the color display device based on the color information supplied in said step (c) and the item data provided in said step (d).

Claim 8

A display system for use in an NC system including an NC unit for administering numerical control and an automatic programming unit for administering automatic programming, the display system being connected between the NC unit and the automatic programming unit and comprising: an operator panel having a plurality of keys including a mode key for selecting modes including an NC mode and item display request keys for generating item display request signals; a control unit coupled to said operator panel, said automatic programming unit and said NC unit, said control unit including: means for storing a predetermined correlation between items to be displayed and corresponding display colors and for providing display color information as an output; and means for receiving one of the item display request signals from the operator panel when one of the item display request keys is actuated, for providing the name of the item corresponding to the item display request signal to the NC unit which in turn generates item data, and for causing said storing means to provide display color information corresponding to the item to be displayed; and a display device, coupled to the NC unit when the numerical control system is in the NC mode and coupled to said control unit, for receiving the item data corresponding to the item to be displayed from the NC unit and for receiving the display color information from said storing means, said display device displaying the item for which display has been requested in the color corresponding to the display color information.

Claim 9

A display system for use in an NC system including an NC unit for administering numerical control and an automatic programming unit for administering automatic programming, the display system being connected between the NC unit and the automatic programming unit and comprising: an operator panel having a plurality of keys including a mode key for selecting modes including an NC mode and item display request keys for generating item display request signals; a control unit coupled to said operator panel, said automatic programming unit and said NC unit, said control unit including: means for storing a predetermined correlation between items to be displayed and corresponding display colors and for providing display color information as an output; and means for receiving one of the item display request signals from the operator panel when one of the item display request keys is actuated, for providing the name of the item corresponding to the item display request signal to the NC unit which in turn generates item data, and for causing said storing means to provide display color information corresponding to the item to be displayed; and a display device, coupled to the NC unit when the numerical control system is in the NC mode and coupled to said control unit, for receiving the item data corresponding to the item to be displayed from the NC unit and for receiving the display color information from said storing means, said display device displaying the item for which display has been requested in the color corresponding to the display color information.

Claim 10

A system as set forth in claim 6, wherein said display device includes: a frame memory including a plurality of RAMs corresponding to the number of colors to be displayed, so that an item image is stored in the frame memory based on the item data and the corresponding display color information, said display device including means for scanning the frame memory to display the item data in color.
