Description

TECHNICAL FIELD The present invention relates to a method for displaying tool trajectories, and more particularly, to a method for displaying tool trajectories for numerical control devices on a CRT screen that allows easy confirmation of the results of the trajectories.

Conventional technology Traditionally, automatic programming devices and CAD/CAM
A tool trajectory for machining the object is calculated by the device. Various methods have been proposed for checking the trajectory by displaying the calculated results on the screen of a display device. "Calculation result display method" shows an intersection calculation method that displays the line segments input to find the intersection, gives a name to the obtained intersection, and displays its numerical data so that it does not overlap with the figure. ing. Furthermore, in the "Drawing Method for Numerical Control Devices" disclosed in Japanese Unexamined Patent Publication No. 62-198908, it is necessary to provide color-specific data for the type of tool path (cutting path or idle feed path) and display paths of specified colors. R for 1 display
AM is realized with small capacity. Also, JP-A-62-22
In the ffNc machining data drawing check device disclosed in Japanese Patent No. 8353, each tool is displayed in a color so as to be suitable for drawing checks such as cycle machining. Furthermore, JP-A-62
Publication No. 121511 states, "The numerical control device J flickers the tool trajectory position and displays its data. In this case, the type of interpolation operation of the tool is determined from the shape and character data. Therefore, the direction of movement of the tool path can be determined easily.

In this way, conventionally, in order to indicate the position of the displayed tool trajectory,
Mark display by marking means and flashing display by flicker means are used, but the shape becomes complicated and
Furthermore, since minute parts become unclear, it is difficult to clearly determine the locus position of the target tool.

Purpose The purpose of the present invention is to solve such conventional problems, and when displaying the calculation result of the tool trajectory on a CRT screen, it is easy to judge and identify and check, and the tool trajectory and interpolation operation of the tool can be clearly defined. The object of the present invention is to provide a method of displaying a tool trajectory that can be grasped.

Configuration In order to achieve the above object, a tool trajectory display method according to the present invention displays a tool trajectory shape in a first area of a display screen based on tool trajectory data read from a storage medium, and displays the tool trajectory shape in a first area of a display screen. When one of the tool path elements constituting the tool path shape is specified in the order of the path, the specified element in the tool path shape is displayed in different colors for linear interpolation elements and circular interpolation elements, and the configuration data of the specified element is displayed. is displayed in characters in the second area of the display screen, the elements passed through to reach the specified element are displayed in other different colors, and the tool path element displayed in the first area and the above are displayed. The feature is that the configuration data displayed in characters in the second area is sequentially displayed in the third area in an interactive manner.

Further, when the tool trajectory shape displayed in the first area is composed of a plurality of blocks, a different designated color is used for each block.

Hereinafter, the configuration of the present invention will be explained in detail by way of examples.

FIG. 2 is a block diagram of a numerically controlled tool locus display system showing an embodiment of the present invention.

The display system according to the present invention includes a control unit 11 that executes 1-display processing, a memory 13 that stores tool trajectories generated by the control unit 11, a keyboard 12 that inputs operation information from an operator, and a 1-display control unit 15. It is composed of a single screen display section 14. The double-sided display section 14 is a CRT display that displays various messages from the control section 11 to the operator as well as the tool trajectory shape and its configuration data, and is controlled by the display control section 15.

The system and the operator can interact with each other through the screen display 14, and the operator can visually check the tool trajectory data.

FIG. 1 is a flowchart of tool trajectory display processing showing one embodiment of the present invention.

The program for tool trajectory display processing is executed by the control unit 11 shown in FIG. First, by specifying and inputting tool trajectory data to be processed from the keyboard 12, the control section 11 reads the specified tool trajectory data from the memory 13 (step 1), and displays this tool trajectory data on the screen display section 14. (Step 2). Next, control section 1
Step 1 is to specify the elements that make up the tool path data (Step 3).

Performs three processes for each specified element. One is to display passed tool path elements in different colors (step 4), and the other is to distinguish the type of tool path elements and display them in different colors for each type. Yes (step 5), the last one is to display configuration data of tool path elements (step 6).

In this way, when creating tool path data for numerical control and displaying the results, the present invention not only displays the shape but also (a) changes the color of arbitrarily specified tool path elements for each interpolation element. By displaying (b) displaying passed elements of the tool path in different colors, and (c) displaying numerical data such as coordinate values near the shape, it is possible to easily check the results of the tool path. That's what I do.

FIG. 4 is a layout diagram of areas displayed on the screen of the screen display section in FIG. 2.

In the left half of the screen, there is a tool path shape display area 2°1, in which the tool path shape is displayed. Further, in the upper right of the screen, there is a configuration data display area 202 of the tool trajectory shape element, in which numerical data such as coordinate values are displayed. Furthermore, at the bottom right of the screen, there is a progress instruction area 20 for tool path elements.
3, and here, as shown in the detailed diagram to the right, the total number of elements (lOO), the number of elements to advance (n), and the number of remaining elements (80) are displayed. Interactive operations with the operator are performed using the advance instruction area 2.03 of the tool path element and the keyboard 12. Advance instructions for tool path elements are
The tool path elements are specified sequentially in the order of path progression from the starting point.In this case, there are two methods: one method to advance one step at a time, and one method to specify and input the number of steps to advance and advance by the specified number. The tool trajectory element progress instruction area 203 displays the total number of tool trajectory elements and the remaining number of elements after subtracting the number of displayed elements. The number of elements to be advanced n is the number of elements to be advanced by the specified number described above.

FIG. 3 is a flowchart 1 of the detailed operation of FIG. 1.

First, by inputting the specified tool path data to be processed from the keyboard 12 (step 101), the specified tool path data stored in the memory 13 is read (
Step 102). Next, the display control unit displays the tool trajectory shape on the CRT screen in the first specified color (step 103). For example, let the first designated color be light blue.

Next, by specifying a tool path display element (step 104), when the progress is made as specified, the display of the passed tool path element is changed to a second specified color (step 105). For example, let the second specified color be yellow. Through this process, the tool path progression order and current position can be easily determined at the boundary between white and yellow. Next, it is determined whether the tool path element at the current position specified by the tool path instruction (step 104) is a linear interpolation element or a circular interpolation element (step 106), and if it is a linear interpolation element, a third specified color is displayed. The display is changed to (step 107). In addition, when it is a 1-circular interpolation element, the display is changed to the fourth designated color (step 1o8
). For example, green is designated as the third designated color, and purple is designated as the fourth designated color.

The specified tool trajectory element is displayed in a specified color, and its numerical configuration data is displayed in the configuration data display area 202 of the screen of the screen display unit 14.

When it is a linear interpolation element, the X and Y coordinate values of its start and end points are displayed, and when it is a circular interpolation element, the XY coordinate values of the start and end points of the arc and the arc element data are displayed.

FIG. 5 is a diagram showing a display example of the tool trajectory shape and tool trajectory data displayed on the screen display section of FIG. 2. FIG. Figure 5 (

In (a), “S” is displayed in the tool path shape display area 201.
The configuration data display area 202 shows the configuration data of the element, including the data name (IS6), the starting point XY coordinate values (17, 131, 6, 103), and the ending point xYP! The floating value (17,131,1,713) is also in the progress instruction area 2.
03 indicates that the number of remaining data is 28 out of 30, that is, the position of the thick line in S is currently specified. On the other hand, in (b), the shape of Ir5j is displayed in the tool path shape display area 201, and the XY coordinates (17,
131, 1, 713), the input tangent angle at the start point (A329, 06), and the output tangent angle at the end point (A329, 06) as arc element data.
8,80), the size of the radius (11,479), and the rotation method of the arc (clockwise or counterclockwise, here counterclockwise L
) and the XY coordinates (24,789,0,214) of the end point are displayed. Further, in the progress instruction area 203, the remaining data number 27 out of the data number 30, that is, the current S
It is displayed that the arc position of the thick line has been specified.

In addition, as another data display method, the xy of the center of one circular arc
It is also possible to display coordinates, starting point angle, ending point angle, etc. In addition, although numerical data is displayed in the example,
It is also possible to display block data of an NG program. For example, in the case of linear interpolation elements, GOIXlo

Specifying tool path display elements in Fig. 3 (Step 10)
By repeating step 4), you can find out the numerical data of the element you want to check.

As described above, in this embodiment, by displaying the entire tool trajectory shape in a designated color for each linear interpolation or circular interpolation element, it is possible to visually understand the interpolation operation of the tool. In addition, the tool path data editing system
By applying the present invention, correspondence with the program list can be easily changed without error.

FIG. 6 is an organized diagram of color display in FIG. 1. When actually displaying, the first color, second color, and third color alone are insufficient, so coloring can be performed as follows.

Initially, the tool path shape is displayed in white, then the target path is displayed in light blue (first color), and among the target interpolations,
The straight line part is displayed in green (second color), the arc part is displayed in purple (third color), and the completed interpolation is displayed in yellow (fourth color) until the target trajectory is reached. The trajectory that passed through is displayed in red.

FIG. 7 is a diagram of a display screen showing another embodiment of the present invention.

In FIG. 7, the specified color is changed and displayed for each block (island). Here, [rSJ] shown in Fig. 7 and “
An independently continuous tool trajectory, such as the character trajectory "0", is called an island.To specify a tool trajectory display element from the keyboard 12, a block name is attached, and as shown in FIG.
! Initially displayed in white, only the part of the target locus is changed to light blue (first specified color), completed interpolation is changed to yellow (second specified color), and straight line interpolation is changed to green (second specified color). 3 (specified color)) and 1-circular interpolation is made purple (4th specified color), and the trajectory portions that have passed are made different colors such as red, orange, pink, etc. depending on the block. In other words, when passing the first block (island) it turns red, when passing the second block (island) it turns orange, when passing the third block (island) it turns pink, and when passing the fourth block (island) it turns red. When it passes through the th block, it changes color to yellow ocher, and so on, changing the color for each block. This makes it clear which blocks have been completed and which blocks are still in progress, as well as which blocks are currently being targeted. In addition to changing the color of the blocks that have been passed, it is also possible to use different colors for the target trajectory for each block.

In this way, in this embodiment, a tool trajectory for numerical control is created and the results are displayed.

In addition to displaying the shape, optionally specified tool path elements are displayed in different colors for each interpolation element, and when multiple blocks are displayed on one screen, each block is displayed in a different color, and the Since numerical data such as coordinate values is also displayed, it is possible to easily confirm the results of the tool trajectory.

Effects As explained above, according to the present invention, the calculation results of the tool path are displayed on the CRT display.

The tool path shape is displayed in a different color for each interpolated element, and its numerical data is displayed for each element in a separate area from the path display area, making it easy to identify and check the tool path. At the same time as designation, elements that have passed the designation are also displayed in a different color, which has the advantage of allowing one to intuitively grasp the tool trajectory order and tool interpolation motion.
