Abstract
Abstract A method for displaying the configuration of a workpiece and the machining device of a numerical control machining apparatus in which it is possible to individually and simultaneously display enlarged images of selected portions. An input section of the numerical control apparatus is operated to input data indicative of the machining apparatus, the initial configuration of the workpiece, and the desired final configuration of the workpiece. This data is operated upon to obtain configuration data for display on the graphics display device. A selection number is then inputted for selecting the regions from the figure to be displayed. Viewing points representing centers of the various figures and images and scale factors for the plurality of regions to be displayed are then inputted. The images of the regions to be displayed are next scaled and clipped accordingly. The image data is then stored in the memory section for ultimate display on the graphics display device.

Claim 1
Independent Claim
216 words
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 on said graphics display device in the form of an image of a figure; selecting a number N of regions of said figure which are desired to be subsequently displayed on said graphics display device; inputting said number N as a display division selection number; dividing the display area of said graphics display device into N portions; 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 simultaneously displaying said images stored in said memory section on said graphics display device with one of said images being displayed within each one of said N portions.
Claim 2
Dependent Claim
216 words
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 on said graphics display device in the form of an image of a figure; selecting a number N of regions of said figure which are desired to be subsequently displayed on said graphics display device; inputting said number N as a display division selection number; dividing the display area of said graphics display device into N portions; 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 simultaneously displaying said images stored in said memory section on said graphics display device with one of said images being displayed within each one of said N portions.
Claim 3
Dependent Claim
