Abstract

PURPOSE:To produce an NC part program by supplying only the desired data in an interactive way after giving the real numbers successively and in an interactive way to the variables included in the pictures displayed on a screen. CONSTITUTION:A screen picture for producing a graphic definition sentence is produced with use of the variable symbols for expression of the form elements of a parts. While another screen picture is produced with use of the variable symbols for expression of the numerical values needed for production of a movement definition sentence. These two screen pictures are registered together with each memory number. Then a processor reads a screen picture 11 of a designated picture number out of a memory and displays it on a display screen DSP together with its setting sentence 12a. An operator gives the real numbers successively to the variables included in the picture 11 through a keyboard in an interactive way. These given real numbers are stored in the memory and at the same time the variable symbols displayed on the DSP are replaced with those supplied real numbers. These operations are repeated for production of an NC part program using an automatic programming language.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a method for creating an NC part program in an automatic programming language interactively using a display screen. Concerning how to create a program.

<Prior art> As a method for creating NC data, [1] APT (Automatically Pr

A method for creating N-equivalent C device decoding 11-function C data such as O code (referred to as the first method); (2) inputting data necessary for creating NC data interactively using a graphic display screen (7. There is a method (referred to as a second method) of creating NC data that can be read by an NC device using the input data.

In the first method, the points, straight lines, and arcs that make up the part shape are defined using an automatic programming language (shape definition),
Next, define the tool path using an automatic programming language using defined points, straight lines, and circular arcs (define the moving vehicle),
Then, using an NC part program written in an automatic programming language created by the program, it is converted into NC data that can be read by the NC device, such as EIA code or ISO code. For example, when creating NC data for moving a tool along the outline OLC of a rectangle RT shown in Fig. 3, first the four corner points Pi of the rectangle RT are -1°2
# 3 # 4) as P1 = 10.10 P2 = 90.10 P3 = 90.50 P4 = 10,50 (shape definition), then using these defined points, FROM, P (0 , O), 02 -- ・(al

Convert to data. In addition, (al is data that specifies the machining start point, p (o, o) is the coordinate value of the machining start point on the X-Y plane, and the number before the alphabet Z is the Z direction coordinate value of the machining start point. Further, (b) is data specifying that the F code (feed rate code) is 100, (C) is data specifying the machining end point, and (d) is data indicating the program end.

On the other hand, in the second method of creating NC data in an interactive format, the relevant information at the time is displayed on the display screen, and sentences are displayed for questions in everyday language. By sequentially inputting various data such as part dimensions and processing process data, all data necessary for creating NC data will be automatically input, and finally NC data that can be read by the NC device will be automatically created.

<Problems to be solved by the invention> In the first method, only necessary data is input! However, the process of creating an NC part program using an automatic programming language is complex and requires a considerable amount of programming time, and the operator is required to understand the automatic programming language and requires considerable skill. There is a problem that.

Furthermore, in the second method, data can be input interactively using a display screen and a keyboard, so there is an advantage that the necessary data can be input sequentially according to the questions and the data input operation is simple. However, if such a second method is adopted, t
Cosystems are usually designed to be general-purpose.

For this reason, the screens and questions that are displayed from time to time are not necessarily necessary when creating an NCC model, and therefore it is necessary to enter unnecessary data or identify unnecessary data. It becomes necessary to omit inputting the data.

From the above, it is an object of the present invention to provide a method for creating an NC part program that has both the advantages of the conventional first and second methods.

Another object of the present invention is to provide a method for creating an NC part program in which an NC part program can be created in an automatic programming language by interactively inputting only necessary data.

Means for Solving the Problems> The present invention uses figure definition statements created in an automatic programming language that define shape elements such as points, straight lines, and circular arcs constituting a part shape, and these defined shape elements. This is a method for creating an NC part program that includes a motion definition statement created using an automatic programming language that defines a tool path using the following methods. , and a screen image in which the data necessary for creating the motion definition statement is expressed using variable symbols are registered respectively, fb) Display the specified screen image on the display screen, and (C1 An NC part program is created by sequentially giving real numbers to variables included in the displayed screen image in an interactive manner.

<Function> If you create a dialogue screen in advance that asks only the data necessary for creating an NC part program that automatically composes the language and register it in the system, you can use the predetermined dialogue screen to interact. Enter only the necessary data! NC part programs can be created by For example, when machining parts of the same shape but with different dimensions is required, there is an interactive screen that sequentially asks the dimensions of the tool path, as well as information such as the machining start point, machining end point, feed rate, and spindle rotation speed that are required for machining. If you register dialogue screens that ask questions about processing auxiliary data, etc., you can input the necessary data using these dialogue screens! With this tool, you can create an NC bird program that includes figure definition statements and motion definition statements for machining parts of the same shape with different dimensions.

Therefore, in the present invention, a screen image for creating a figure definition statement in which each shape element constituting a part shape is expressed using variable symbols in tool paths, and data necessary for creating a motion definition statement are expressed using variable symbols. Register each expressed screen image, display the specified screen image on the display screen, and create an NC part program by sequentially giving real numbers to variables included in the displayed screen image in an interactive manner. I try to do that.

<Example> FIG. 1 is an example of a dialog screen according to the present invention, and FIG. 2 is a flowchart of processing according to the present invention. It is assumed that NC data for machining is created by moving the tool along the outer shape OLC of the rectangle RT shown in FIG.

The coordinate values for specifying each shape element of the part are expressed by the variable symbol V.
A screen image for creating a figure definition statement expressed using i (i = 1.2...) and a screen image expressing the numerical value necessary for creating a motion definition statement using the variable symbol Vi. Create a number and register it in the memory of the automatic programming system. Note that screen image data for creating a figure definition statement is created and registered so that the variable symbols of each shape element are displayed on the display screen along the tool path, in other words, in the order of tool movement.

For example, in Figure 3, move the tool from point P1 to P2.
If it is to be moved in the order of →P3 →P4, the screen image for creating the figure definition statement will be “starting point...X-■1.Y-
■2...(a) Runner-up, -X=V3. Y=V
4 - ・-fb1st runner-up...X; V5. Y2v6
...(c) Runner-up ---X=V7. Y=V8°'
-...(dl. Note that (a) to (dl are each point 1. P 1 ).

P2. P3. This is a variable that indicates the coordinate value of P4. In the case of Figure 3, the screen image for inputting data necessary for creating a motion definition statement is "Processing start position...X = V10. Y = V11.
Z=V12 feed speed...F=V100 Machining end position...X=V20. Y=V21. Z＝
V22''.Hereinafter, the method of the present invention will be explained according to the flowchart of FIG.

Enter ENguchi to specify. Note that the mouth is a number that identifies the screen image.

Set the screen image number for creating the figure definition statement in Figure 3 to 1,
If the screen image number for creating a motion definition sentence is 2,
First, input 5CREEN 1 from the keyboard.

(2) As a result, the number of processors in the automatic programming system is changed from 1 to 1.

(3) Then, the processor reads the screen image 11 of image number 1 from the memory and displays the screen r)S.
In addition to displaying in P, question sentence 12 of the first variable vl
a (see FIG. 1(A)). Furthermore, i =
In No. 1, the question is as follows: The X coordinate value of the first point P1 is asked.

(4) Post-operation - Yu inputs a numerical value from the keyboard and gives a real number to the first variable v1.

(5) If a numerical value (real number) is not input, the numerical value is stored in the memory, and the variable symbol IT V j I+ displayed on the display screen DSP is replaced with the input numerical value (see Figure 1 (B )reference).

Regarding (6), the processor manually checks whether all variables of the displayed screen image are set to real numbers.

(7) If real numbers are not assigned to all variables, the first processor repeats the process from step (3) as i4-1→l.

(8) Real numbers are returned to all variables of the displayed screen image. First, if the screen image is for creating a figure definition statement, create a figure definition statement, and use it for creating an interlocking definition statement. Create a motion definition statement, if any.

(9) Next, the processor displays the display screen D
An image prompting the user to input the next screen image number is displayed on S l). This 11 (from this point on, the operator is Nc Nana)
All screen image variables (and real numbers required for creation)
If the screen image number is not given, a new screen image number is input in step (1) and the subsequent processing is repeated. In addition, in the forced operation shown in Figure 3, input 5GFtEEN 2 from the keyboard after inputting the variables of the screen image for creating the figure definition statement, and then input 5GFtEEN 2 from the keyboard.
) A screen image 12 for creating interlocking definition sentences and a question sentence 12c are displayed.

(Ifll (, then the t created in the following steps)
The NC data creation process is completed by converting the NC part program written in the automatic programming language into NC data such as EIA or Is(') code that can be read by the NG device using a well-known method.

The above is a case where the part shape can be defined by a point sequence (PI, P2.P3.P4), but if a straight line or arc is required to define the part shape, points, straight lines, A mixture of circular arcs is defined. t: For example, as shown in Fig. 4, move the tool from point P1 to point 1-P2 to straight line S1 to arc C1.
If you move point P5 → PO, in l-P 1 (
