Abstract

PURPOSE:To shorten the drawing time and to easily recognize the display contents by drawing the NC data after thinning it with the designated value. CONSTITUTION:An NC data file name, the thinning value, a display speed, a display range, etc., are stored in a display condition data memory 5. When the display of data is started, the designated one of NC data to be stored in an NC data memory 2 is called out and sent to a display data extracting part 6. This NC data is divided into the scan parts (a) and the pick parts (b) and sent to a thinning process part 7. If the thinning value is designated as '2', for example, the part 7 thins two parts (a) for each new part (b) after one part (a) is through and sends the NC data to a display control part 8. The part 8 controls the received NC data according to the designated display speed and display range and sends it to a locus data display part 9. Then the part 8 displays an animation on the screen of a CRT 10 and then displays a locus. Consequently, the drawing time is shortened and the display contents are easily recognized.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for graphically drawing NC data.

Conventional technology Conventionally, when performing a trajectory check by drawing graphics on NC data created based on screen information or model data by an automatic programming system, etc., the data stored in the NC data memory is designated and the contents are A method of sequentially drawing graphics while reading the data is being used.

Problems to be Solved by the Invention The drawing method described in the conventional technology requires a large amount of time to draw when a huge amount of NC data is generated, such as NC data created for mold processing. There are some problems, and like the NC data for finishing, the pick (41
If the pitch is fine (1 pitch), the separation of lines on the screen becomes unclear, making it difficult to grasp the content of the trajectory. Furthermore, if the area is divided and enlarged to make it easier to understand the content, a problem arises in that a large amount of drawing time must be spent to see the whole thing.

The present invention has been developed in view of these problems of the conventional technology, and its purpose is to shorten the drawing time and understand the displayed content by thinning out the NC data by a specified amount and drawing it. The purpose of this invention is to provide a method for displaying NC data that is easy to use.

Means for Solving the Problems In order to achieve the above object, the NC data display method of the present invention thins out and displays NC data created by computer processing from drawing information or model data according to externally input conditions. It draws graphics while controlling it.

Further, the thinning process can also be such that the NC data is divided into a scan section and a pick section, and the NC data is thinned out until a specified thinning amount is reached each time the pick section comes.

Input conditions such as effect thinning amount 9 display speed 9 display range externally,
The NC data is called up and distinguished into the scan part and the pick part, and each time the pick part comes, the NC data is thinned out by the specified thinning amount, and this thinned data is processed under conditions such as display speed 9 display range. The trajectory is displayed while

Embodiment An embodiment will be explained with reference to FIGS. 1 to 3. In the block diagram of FIG. 1, an NC data input section 1 is a section for inputting NC data created by an automatic program, etc., and an NC data memory 2 is a section for storing this input data. Keyboard 3 enters N in display condition input section 4.
File name of NC data stored in C data memory 2.

The display conditions such as thinning amount 3 display speed 2 display range are input.The display condition data memory 5 is the part that stores this input data. According to the NC data file name specified, the specified NC data stored in the NC data memory 2 is called up, and the scan part (processing data in the scanning direction) a and the pick part (scanning interval) are retrieved.
The thinning processing unit 7 in the part distinguished from b is the part that performs the thinning processing of the scanning part by the specified thinning amount.The 0 display control unit 8
is the display speed of thinned data.

This is the part that sends data to the trajectory data display section 9 while controlling according to specified conditions such as the display range, and the trajectory data section is the part that displays the trajectory as an animation on the screen of the CRTIO using this data.

Next, the operation of this embodiment will be explained. keyboard 3
NC data file name 1 thinning amount.

Display Daruma 1 When display condition data such as the display range is input, the specified conditions are stored in the display condition data memory 5 via the display condition manual section 4.0 Next, when data display starts, the NC
Specified data is called out from among the NC data stored in the data memory 2 and sent to the display data retrieval section 6.The 0 display data retrieval section 6 sorts the sent NC data into a scan section and a pick section. Separately, 0 is sent to the thinning processing section 7. In the thinning processing section 7, if the thinning amount is specified as 2, for example, each time one of the scanning sections a is finished and the pick section comes, two scanning sections a are thinned out and displayed. M
? Send NC data to Tj unit 8. The display control section 8 sends the thinned out data to the trajectory data display section 9 while controlling it according to the specified display speed and display range.
The output signal from the trajectory data display unit 9 is used to display the trajectory on the screen of the CRTIO as an animation. Therefore, the trajectory displayed on both sides of the CRT is normally displayed as shown in Figure 2, but the trajectory is thinned out. When the amount is 2, the trajectory is displayed as shown in FIG.

In Figures 2 and 3, in order to make it easier to understand the state of the thinning display, the picks are displayed as coarser picks than in reality. The content of the locus is easy to see in the diagram, and Figure 3 is easy to read.

Effects of the Invention Since the present invention is configured as described above, it produces the following effects.

Since the NC data is thinned out according to the input conditions and drawn on the graphic, it is possible to shorten the time required for one stroke, and the display is easier to see, making it easier to understand the trajectory contents. Since the operator can input designations of display conditions such as quantity 1 display speed, efficient work is possible.
