Graphics display method for numerical control apparatus

A display method for a graphics display device of a numerical control apparatus for displaying graphic data relating to a machining apparatus and a workpiece, comprising:

• operating an input section of said numerical control apparatus to input data relating to said machining apparatus, data relating to an initial configuration of said workpiece and data relating to a final configuration of said workpiece;
• performing calculations on said data thus inputted to obtain configuration data;
• displaying said configuration data as an image of a figure on said graphics display device;
• inputting a selection number corresponding to the number of regions of said figure which are to be displayed on said graphics display device;
• inputting viewing points and scale factors for said regions, said viewing points being points geometrically predetermined from boundaries of said regions, said regions being distinct from each other as viewed in said figure;
• scaling and clipping the images of said regions in accordance with respective ones of said viewing points and scale factors;
• storing said images thus scaled and clipped in a memory section;
• and
• displaying said images stored in said memory section on said graphics display device in one of a simultaneous and sequential manner.

• displaying said configuration data as a figure on said graphics display device;
• inputting, as a selection number N, a number, greater than 1, of regions of said figure displayed on said graphics display device, said number N representing the number of regions of said figure to be subsequently separately displayed;
• inputting viewing points and scale factors for said selected regions, said viewing points being points geometrically predetermined from boundaries of said regions;
• scaling and clipping the images of said regions in accordance with respective ones of said viewing points and scale factors;
• storing said images thus scaled and clipped in a memory section;
• and
• controlling said graphics display device so as to sequentially display the images stored in said memory section.
