Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in an interactive data input method in a CNC machine tool.

[Conventional technology]

The interactive data input method for CNC machine tools is such that a machining program is created by an operator such as a machining engineer who responds to questions according to the questions on an interactive input screen displayed on a cathode ray tube. This is configured to be carried out by inputting necessary data read from the machining drawing of the workpiece using a keyboard or the like.

[Problem to be solved by the invention]

In the data input process, the data written in the processing drawings includes relative dimension values, polar coordinate instructions, etc., and there are cases where it cannot be input as is and pre-calculations such as conversion to absolute dimension values and orthogonal coordinates are required. For this reason, systems equipped with a mathematical formula input function are also provided, but these also have a monovalent (one value) function.
There was no function to calculate multivalued (two or more items) values such as conversion from polar coordinates to orthogonal coordinates.

In addition, in order to accept both the orthogonal coordinate values and polar coordinate values, it is necessary to provide each input item on the dialog input screen, which increases the number of questions and makes the screen complicated.
Although it was highly functional, it had the drawback of being difficult to operate.

SUMMARY OF THE INVENTION An object of the present invention is to provide an interactive data input method that eliminates the above-mentioned drawbacks of the prior art, allows interactive input without the need for pre-calculation, and improves functional operability.

[Means to solve the problem]

In order to achieve the above object, the present invention displays a guide map that can be selectively displayed according to a plurality of patterns and question items corresponding to the guide map on the same dialog input screen, and displays items to be input on the guide map. In an interactive data input method, a cursor etc. is automatically displayed at the relevant position and question item, and the data written on the machining drawing of the workpiece is entered using a keyboard etc. according to this display to create a machining program.
When inputting special data that cannot be entered by direct value input or mathematical input, such as polar coordinate data, sexagesimal angle data, tolerance dimension data, circumferential speed and tool diameter spindle rotation data, etc., on the machining drawing, For these input items, input the data written on the processing drawing as is, input a data delimiter between the input data in one input item, and calculate the number of input data and the input item. From the type, polar coordinates are converted to orthogonal coordinates, sexagesimal angles are converted to decimal angles, tolerance dimensions are converted to center values with tolerances, circumferential speed and tool diameter are converted to spindle rotation speed, and these special data are converted to the number of rotations of the spindle. The settings are automatically converted or converted into the settings display method internally and displayed.

[Effect]

When inputting data written in a method different from the input method of the relevant NC on the processing drawing, enter the data as is, but by inputting a data delimiter between the data, it is possible to input the data directly. Unlike normal input methods such as value input and formula input, the input data is identified as special written data, and then the input data is processed mathematically in a method corresponding to the input item, and the NC is displayed. Since the settings are displayed after being converted or converted into a method, there is no need for any pre-calculation. In addition, in the case of polar coordinates, the orthogonal coordinate values, for example, the X coordinate value and the Y coordinate value, can be set and displayed all at once in one input item, and the Y value and Y value can be input in separate fields as in the past. The number of operations can be reduced compared to the case where the settings are displayed separately. Moreover, the question items are the same as before, and the dialogue input screen will not be complicated (However, if multiple items are set and displayed at once, only the set question items will be displayed. It is something that makes you

〔Example〕

As shown in Fig. 1, the present invention roughly divides the data written in the processing drawings into normal written data and special written data, and the normal written data can be input as usual, that is, by direct value input or numerical formula input. For special written data, enter the data exactly as it is written on the processing drawing, but do not use a comma symbol between each data.
etc., the input data is processed mathematically in a method corresponding to the input item, converted or converted to the display method of the NC, and the settings are displayed.

As shown in Figure 2, the above input is made to the processing information processing computer (2) using the numeric keys and various function keys on the keyboard (1), and the information displayed on the cathode ray tube (3). The test is conducted in the form of a response to a diagram and questions corresponding to the guide map.

The above guide map classifies the machining shape of the workpiece into several basic patterns and can be selectively displayed on the cathode ray tube (3) by pressing the selection key for each pattern, and the questions corresponding to the guide map are displayed. displayed on the same screen.

Figure 3 shows an example of the dialogue input screen displayed on the cathode ray tube (3).The guide map (4) is displayed on the right side of the screen, the question items (5) are displayed on the left side, and the machining shape is L-shaped. The case is shown below. An item cursor (6) and a guide map cursor (7) are displayed blinking in the corresponding column of the question item (5) and the corresponding location of the guide map (4). In the case of the example in Figure 3,
Question item (5) is to set the X and Y coordinates of the reference position, and then set the machining width, inclination angle, corner dimensions,...cutting (
(Start) direction is set sequentially, items to be set are indicated with an item cursor (6), and corresponding setting points are displayed with a guide map cursor (7).

The input data is displayed in setting 5 (8) at the bottom left of the screen, and is processed by the computer and displayed in the corresponding part of question item (5) to notify that it has been set.

An example of the setting process for the above input data will be explained in Table 1 attached hereto.

Table 1 exemplifies coordinate values, angles, width dimensions, and rotation speeds as input item types, and for each item, provides an overview of the conventional processing method and the processing method of the present invention, and a vertical comparison of execution examples. it's shown.

First, regarding coordinate values, when inputting coordinate values in the format of 100X CO530° as input data that can be read from the processing drawing, conventionally, rloo J, "*" (this is a multiplication symbol), rcO5J, and "30 By pressing the input key after inputting ", r 86.603 J is calculated as one data by formula processing, and this is set as one coordinate value of the orthogonal coordinates. However, in the present invention, rlooo , and the data delimiter ``,j'' and ``30'' and press the input key.This input item is related to coordinate values, and the number of input data is 2, so it is an input using radial coordinates. I made a self-judgment,
Each data is automatically processed internally using formulas (example: X = 10
0 CO53Q°, Y=100 sfn30m),
Converted to Cartesian coordinates: X = 86.603, Y = 50.
Display the settings for 000 all at once.

Regarding the angle, if it is displayed in sexagesimal format in the form of "20 degrees 45 minutes" on the processing drawing, conventionally it is '20 degrees 45 minutes'.
It is converted into a decimal angle as 0+45/60J and input as one data, but in the present invention it is input as r20.45J, the input item is an angle, and the number of input data is 2.
Since the above is the case, it is determined that the input is a sexagesimal angle, and it is internally converted to a decimal angle, r20.7
If the angle is set and displayed as 5 J, and the angle is displayed in the format of "O degrees mouth minute Δ seconds", the number of input data according to the present invention is three.

Next, width dimensions are displayed with tolerances (e.g. upper limit 0.
1, lower limit 0.3), conventionally rloo
+ (0,1-0,3]/2 J was input as one data in the format and the tolerance center value r99.9J was calculated, but in the present invention, '100,0.4.-0.3 J format as 3 data, the input item is the width dimension, and the number of input data is 3, so it is determined by itself that the center value of the tolerance is to be calculated, and the center value of the tolerance is calculated internally.
Set and display as r99.9J.

Regarding the rotation speed, in addition to directly giving the spindle rotation speed, once the workpiece material and the tool to be used are determined, the cutting conditions can be determined as follows.
Since it is determined by the cutting speed, there are cases where the cutting speed is given based on empirical values or recommended values. In this way, when the cutting speed (m/win) and tool diameter (ml) are given, this must be converted into the spindle rotation speed (rpm) and set. 1
In the case of 11 inches and tool diameter of 30φ, conventionally, 10
Replace 0m with the fin, add the π constant rPIJ, etc., and create rloo
000/ [PI*30) J format is input as one data, and the spindle rotation speed r 1061 J is set and displayed, but in the present invention, if input in the format rloo, 30J, this input item can be set as rotation speed. Since the number of data is 2, it is determined by itself that the rotation speed of the spindle is calculated from the circumferential speed and tool diameter, and the calculation is performed internally.
Set and display as 1061 J.

For special written data other than the above, the written data on the processing drawing is input as is, a delimiter is introduced between each data to distinguish it from normal written data, and the setting process is performed internally.

Figure 4 shows the control flow for question items on the dialogue input screen displayed on the cathode ray tube, where "i" indicates the order of the question items, and when dialogue input starts, i=1, and the item The cursor and guide map cursor are moved to the position corresponding to the i=1st input item, the i=1st input data display table value is copied to the setting field key buffer (input data display), and the keyboard If it is a control key, it will process the corresponding control key, if it is a digital key, it will be stored in the key buffer, and if it is an input key, it will set the input data. Let the process take place. That is, the input data setting process determines the number of data in the key buffer input data string, and when the number of data is 1, it is processed as normal written data, and when the number of data is 2 or more, it is processed as the input item type. Setting data is derived from the number of data, and if necessary, n-item batch setting processing and range check processing are performed. Here "n" for n item
is the number of setting items, and "range check" is a check to see if there are any errors in the setting values.

When the above input data setting process is completed, set the next item number of the item cursor and guide map cursor to r i=MIN
((i+n), is+ax)” and (i+n) or (
isax), whichever is smaller, 0. For example,
If we have finished setting the first question item i=1, we will compare (1+n) and (imax), where setting item n is 1 or 2 and i wax is, for example If there are up to 10 items, advance to i-2 or i=3. For example, when setting the coordinate values described above, when inputting data in polar coordinates, n becomes two items.
, y are set all at once.

When the settings for one question item are completed in this way, the respective cursors are moved to the next question item and settings are made for the next question item.

When the settings for one dialog input screen are completed, the next screen is selected and the same questions are asked, and when the settings for all machining shapes are completed, the machining program is edited and the machine is machined using this program. NCl machine
1 to process the workpiece.

〔Effect of the invention〕

According to the present invention, the data displayed on the processing drawing can be input interactively without the need for pre-calculation, and the number of key operations can be reduced. can improve sex.
