Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an interactive programming device that creates an NC program by specifying the product shape of a workpiece.

(Prior Art) In a typical interactive numerical control device, a machining program is created based on shape and dimensional data entered through key input from an MDI device. To help create this program, the tool trajectory of the input program can be displayed graphically on the CRT screen for checking.

In addition, when specifying the product shape of a workpiece through interactive input, the coordinate values of the start and end points of a straight line or arc input as shape data are automatically determined from the previous and subsequent shape data without having to specify the length or angle. It can also be calculated, and various simple input methods have been developed.

For example, if you specify a straight line and then specify the next arc without specifying its end point, the end point of the straight line will be automatically determined based on the calculated intersection point. However, in this case, since two coordinates of the intersection points are generally determined, it is necessary to input additional figure modification information.

(Problem to be Solved by the Invention) Such a conventional operation for selecting a figure is similarly necessary, for example, even when specifying a contour between two circular arcs. In order to specify the intersection of One of them must be selected from the list, and there is a problem in that an operator who is not familiar with the operation is likely to make an input error.

The present invention was made to solve the above problems, and
An object of the present invention is to provide an interactive programming device that can easily specify the outline of a product shape based on a figure displayed on a numerical control device having a screen display function, and can prevent operational errors.

(Means for Solving the Problems) According to the present invention, in an interactive programming device having an arithmetic function for specifying a machining shape from input shape and dimension data, , a designation means for separating and specifying a part of the displayed figure, and a program creation means for creating a machining program corresponding to the designated part of the figure. It is possible to provide an interactive programming device characterized in that when a single shape cannot be determined depending on the shape data, a part of the displayed figure is specified by the specifying means to specify the machining shape.

(Operation) In the interactive programming device of the present invention, when shape data including multiple intersections or contact points is input,
The shapes are displayed on the display means in an undetermined state, and a message is given to the operator to specify a part of the displayed shape separately, so that the machining shape can be specified interactively. ing.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

The 'si diagram is a block diagram showing the configuration of the numerical control device when it is used in the main body of the numerical control device. The processor 1 is connected to a machine tool 2 via a predetermined path line or the like, and outputs machining commands to the machine tool according to a formed machining program. The path line of the processor 1 includes a memory such as a ROM 3 for storing a control program for controlling the main body of the numerical control device, a RAM 4 for temporarily storing data input according to the interactive program function, and a plurality of menus in the machining program. Two screens, a CR7 display 5 for displaying item setting screens, input data, etc., a nonvolatile memory 6 for storing machining programs, etc. are connected. Reference numeral 7 denotes an operation panel having soft keys such as an MDI device.The operation panel 7 controls the display of the CR7 display 5, and the operator sequentially performs key operations to proceed with interaction with the screen by making necessary selections. Then, in response to a command from the operation panel 7, a screen for specifying the contour shape necessary for creating the program is displayed on the screen of the display 5.

FIG. 2 is a flow chart showing an example of a program input method in an interactive numerical control device.

This is an operation controlled by the processor 1 as part of the control program in the ROM 3, and even if it is applied to an interactive programming device, it may be an arithmetic device, a storage device, a CRT screen display device, M
If a DI key input device or the like is included, the same effect will be achieved.

When the operator inputs the predetermined product shape and dimensions,
A message to assist input is displayed on the display 5 as a program auxiliary screen (step a), and at this time, the product shape determined from the data input up to that time is graphically displayed on the CR7 screen. (Step b
), the operator inputs the data read from the drawing etc. at that point using the MDI key on the operation panel 7 (step C). ), the numerical control device uses the processor 1 to automatically calculate the coordinate values of the undetermined portion, that is, the intersection or contact point between the two shapes, from the already determined shape data before and after the shape.

When two or more intersections or tangent points are calculated, such as between a circular arc and a straight line, or between a circular arc and a circular arc, the display 5 of the numerical control device displays the information for all of the tangent points and intersections, as shown in FIG. Displaying shapes simultaneously (step e)
, in that case, the fact that it is an undetermined portion is indicated by a dotted line. Then, a predetermined message is displayed at the bottom of the screen to allow the operator to select these contact points or intersection points (step f).The operator selects one of the numbered intersection points from the graphically displayed figure and the message. Select one by pressing the corresponding soft key (step g).

In other words, the straight line and arc input by the operator are points 1 and 2.
If the arc designation is CW (clockwise) and you specify 1 with the soft key, the outline will be specified along the small circle from the intersection l, and if you specify 2, the outline will be specified along the small circle from the intersection 2. The contour is specified along the . As a result, a part of the dotted line portion changes to a solid line, and a predetermined figure is determined on the screen.

As a result, the product shape is specified and automatically calculated internally to create a product machining program (step h), which is stored in a predetermined storage area of the RAM 6.

In this way, each step az h described above is repeated until the input of all product shapes is completed (step l), and the program creation is completed. Note that if the shape data does not include any undetermined portions during this process, step 6-wg is omitted. Note that instead of displaying the undetermined portion with dotted lines, a color graphic display may be performed by changing the color of the line segment according to the intersection point, and by specifying the color, a part of the figure may be separated and specified.

As described in detail above, the present invention provides for specifying the outline of a product shape by combining shape data input by an operator in an interactive programming device that has an arithmetic function for specifying a machining shape from input shape and dimensional data. It is particularly effective in carrying out. However, although the present invention has been described herein in connection with the illustrated embodiment, modifications to the detailed parts of the structure and various modifications may be made without departing from the spirit of the invention as set forth in the claims. It is obvious that they can also be changed to a combination of them.

(Effects of the Invention) As described above, according to the present invention, it is possible to provide an interactive programming device that eliminates the difficulty of conventional operations associated with graphic modification and allows easy specification of the outline of a product shape. .
