Abstract

PURPOSE:To know easily a work end state and to reduce a correcting job time by processing graphically both a processing program produced by a designing/ producing device and the data on the processing form and displaying the form of an object to be processed or both the form of said object and a tool locus superposed on each other. CONSTITUTION:The finishing form data on an object to be processed which is designed by a designing/producing device CAD/CAM device 1 with aid of a computer is defined as a processing program 2 containing an EIA code. The program 2 is punched with a tape and sent to an NC device 3. While a finishing form obtained from a coordinate conversion part 7 of the device 1 is converted into the processing form data 8 of a minute segment and applied to a graphic processor 13 provided in the device 3. Then the program 2 received by the device 3 is processed by a processing program processing part 4 and a tool locus calculating part 5 and applied to a display device 6. Then the coordinate plane data 11 designated by a keyboard is read out to a coordinate calculating part 10. Then the address of the device 6 is designated through a screen address designating part 12 after a coordinate calculation. Then the form of the object to be processed and a tool locus are superposed on each other and displayed.

Reference numeral 3 denotes an NC device, 4 a carnivorous nib program processing unit that processes the carnivorous nib program 2, 5 a tool trajectory calculation unit that determines a tool trajectory from the contents processed by the carnivorous nib ρ-gram processing unit 4, and 6 a CRT screen, etc. It is a display device.

Next, the operation shown in FIG. 1 will be explained.

Processing shape data designed by the CAD/CAM device 1 is converted into a nitrogram 2, and a paper tape is perforated using an EIA hood to produce a perforated tape. The NC device 3 reads the contents of the perforated tape into which the programm has been inserted, converts it into machining shape data in the cutting nib pgram processing section 4, calculates the movement of the tool from the machining shape data in the tool trajectory calculation section 5, and calculates the movement of the tool from the machining shape data. The calculated tool trajectory is displayed on the display device 6.

As mentioned above, conventional equipment does not process the shape itself;
Since it is configured to draw the trajectory of the tool, CAD/
There were drawbacks in that it was difficult to understand the shape of the workpiece designed with the CAM device 1, and it was difficult to modify the cannibalogram 2.

[Summary of the invention]

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology, and is equipped with a function that can input and process both machining shape data and machine programs created with a CAD/CAM device into an NC device. The object of the present invention is to provide an NC device that makes it possible to graphically display the machining shape, thereby making it easier to understand the shape, and making it easier and shorter to modify the machining program. An embodiment of the present invention will be described below with reference to FIG.

Next, the operation will be explained.

The finished shape data of the workpiece designed with the CAD/CAM device 1 is the same as before, using the EIA code as a nib μgram 2.
is converted into a perforated tape and sent online or offline to the NC device 3, where it is sent to the perforated tape processing program 2 or the Ni program processing unit 4. Tool path calculation section 5
will be processed.

Separately, in the CAD/CAM system [1], the finished shape is converted by a coordinate conversion section 7 into machining shape data 8 of minute line segments on the coordinates, and transferred to the NC device 3.

In the graphic processing section 13 in the NC device 3, the machining shape data 8 is input to the data input section 9 and temporarily stored.

Next, the coordinate plane data 11 specified from the outside using the keyboard is read, and necessary data is extracted accordingly. In the next step, the coordinate calculation unit 10 calculates the coordinates, and the screen Atome designation unit 12 performs the coordinate calculation on the display device 6 consisting of the CR1 screen.
By specifying an arbitrary position on the screen and printing line segments, a graphic display of the machined shape can be realized.

In the above embodiment, it is difficult to display the machining shape, but the tool trajectory may be displayed superimposed on the machining shape so that both the machining shape and the movement of the tool can be grasped.

〔Effect of the invention〕

As described above, the present invention graphically processes the input information of both the carnivorous program created by the CAD/CAM device and the machining shape data in an NC device that inputs and processes the carnivorous program created by the CAD/CAM device. and a means for displaying the shape of the workpiece or the superimposed shape of the shape of the workpiece and the tool trajectory on the display device, so that the operator can see the completed machined shape through the display on the display device. It can be easily understood by looking at it, and it has the effect of making it easier to modify the Canadian program.
