Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a numerical control device equipped with a graphic display device capable of displaying a tool path.

[0002]

[Prior Art]

 Since the conventional numerical control device displays all the tool paths of the machining program in the same color, when actually checking the NC machining program, it is impossible to know how much one block is. Also, as long as you look at the display, it may not be possible to distinguish between arcs and straight lines.

[0003]

[Problems to be solved by the device]

 In the conventional technique, since all tool paths of the machining program are displayed in the same color, for example, in the case of continuous blocks that are almost smooth, it is not possible to know how much one block is. Further, in the case of a circular arc having a large radius, it may be indistinguishable from a straight line. Also, it is not possible to identify how many blocks have the same sequence number.

The present invention has been made to solve the above problems, and by designating a color-coding method, one block of a tool path can be clarified. It is an object of the present invention to provide a numerical control device that can be distinguished easily and can identify blocks having the same sequence number.

[0005]

[Means for Solving the Problems]

 The above-mentioned objects are: 1-block reading means for reading the NC machining program one block at a time; color-coding designating means for designating which pattern the tool trajectory is to be color-coded; and tool trajectory data of blocks read by the 1-block reading means Tool trajectory data creating means, a color flag setting means for flagging the tool trajectory data with a color specified by the color classification designating means, and a tool with a color flag for storing the tool trajectory with a color flag This is achieved by providing a tool locus drawing means that draws a tool locus based on the color flags in the locus storage table and the tool locus storage table with color flags.

[0006]

[Action]

 The 1-block reading means reads the blocks one by one from the machining program, and the color-coding designating means specifies whether the tool loci are color-coded one block at a time, straight lines and arcs, or each sequence number. The data creating means creates tool trajectory data from the read blocks, the color flag setting means adds color information to the tool trajectory data, and the tool trajectory data with color information is stored in the tool trajectory storage table with color flags. Then, based on the tool trajectory storage table with the color flag, the tool trajectory is drawn by the tool trajectory drawing means.

【Example】

 Example 1. FIG. 1 is a diagram of a numerical controller for executing the numerical control method of the present invention. The numerical controller 1 has a microprocessor (hereinafter referred to as CPU) 2, and the CPU 2 has a ROM 3 for storing a control program and data. RAM4 used for temporary storage of data, non-volatile memory 5 for storing processing programs and parameters, reader / puncher interface 6 for punching out processing programs, printer interface 7 for printing processing programs and CRT data. , A CRT device 8, a keyboard 9, a floppy loader 11 for using a floppy disk, and an axis control circuit 10 for driving and controlling a servo motor of each axis are connected by a bus 12.

FIG. 2 shows a processing flow from color designation to tool trajectory drawing. The operation of this embodiment will be described using this flow.

When the tool locus display is activated, first, each data is initialized (step S1). Here, the initial color is set to color 1. A program for one block is retrieved from the non-volatile memory 5 (step 2), and it is determined whether or not it is a movement command (step S3). In the case of a movement command, the movement amount is calculated and tool path data is created (step S4). If it is not a move command, the next block is fetched. After creating the tool trajectory data, it is determined whether or not there is a color coding designation (step S5). If no color classification is designated, the color remains the color 1 (step S6). If there is a color-coding designation, the pattern is discriminated (step S7), and processing is performed according to the pattern. In the case of color-coding one block at a time, the color of the previously created block is determined (step S8), and if the previous block is color 1, the current color is color 2 (step S9), and the previous block is color 2. If so, the block this time is set to color 1 (step S10). In the case of color-coding with an arc and a straight line, it is determined whether the block is a circular arc block (step S11). In the case of color coding for each sequence, it is determined whether or not the sequence number is the same as that of the previous block (step S14). If the sequence number is the same, the color of the previous block is checked (step S15), and it is set as color 1 or color 2. (Steps S17 and S18). If the sequence number is different from that of the previous block, the color of the previous block is checked (step S16), and the color is made different from that of the previous block (steps S18 and S19). When the color is determined, the color flag which is the information of the color is set in the tool trajectory storage table with the color flag together with the previously created tool trajectory data. Thereafter, the drawing means draws from the color flag and the tool track data in the tool track storage table with the color flag (step S21). After drawing, it is judged whether or not the program is the last one (step S22), and if it is not the last one, the process returns to the process of taking out the program for one block (step S2), and if it is the last one, the processing is finished. Use a key input to specify whether the tool path is color-coded block by block, arc-shaped and straight-line, or color-coded by sequence. For example, if the display and keys shown in FIG. 3 are prepared and it is desired to color-code one block at a time, it is sufficient to press the key 1.

Example 2. Next, a display example when color coding is designated will be described. FIG. 4 shows a case in which color coding is designated for each block, and the display color is switched between color 1 and color 2 for each block. FIG. 5 shows a case where color coding is designated by an arc and a straight line, the straight line is displayed in color 1, and the arc is displayed in color 2. FIG. 6 shows a case in which the color coding for each sequence is designated, and P0, P1, and P2 are sequence numbers. 1, P3 and P4 are sequence numbers. 2, P5 is the sequence No. When 2, P0-P1-P2 is displayed in color 1, P3-P4 is displayed in color 2, and P 5 is displayed in color 1.
