FIG. 36 shows a nonvolatile memory 1 in the NC device 1.
FIG. 6 is an explanatory diagram showing an example in which data stored in the display 6 is displayed on a CRT 19; In FIG. 36, numerical values in parentheses indicate rows and columns when displayed on the CRT 19. That is,-(5,3)-indicates that the data is displayed in the fifth row and the third column.

Generally, when each data is stored in the non-volatile memory 16 in the NC device 1, it is stored according to the data type. That is, double-precision real type data (TY
PE-L) collectively stores only this type of data as shown at 28, while integer-type data (TYPE-N)
As shown in FIG.

As described above, each data in the non-volatile memory 16 is not usually stored completely in correspondence with the order in which the data is displayed on the CRT 19. Sorted and displayed.

The data types of the NC device usually include the following. Double-precision real number type: 8-byte data Real number: 15 digits can be handled Real number type: 4-byte data Real number: 7 digits can be handled Double-precision integer type: 4-byte data Integer type: 8-byte integer can be handled Integer type: 2-byte data 4-digit integer Can handle

Conventionally, when data is input / output to / from an NC device, it is simply performed using an I / F such as RS232C. EIA like the machining program 95
In the case of the machining program described in (1), input and output of data are generally performed using character codes. This is because, when data is stored in the NC device in the machining program 95 of the EIA, the character code is stored as it is, so that input and output can be easily performed using the character code.

In recent years, the number of NC devices incorporating an automatic program function in the NC devices has increased. FIG. 37 is an example of a processing drawing, and FIG. 38 shows an automatic program for processing the work shown here. FIG.
The internal data of the automatic program indicated by {circle around (1)} has a special data structure and is not stored in a character code. Therefore, when the data 96 of the automatic program is input / output, the data stored in the NC device is input / output as it is, not the character code.

When a machining program is created using the above-mentioned automatic programming function, even when machining a workpiece having substantially the same shape, the machining program is only partially different but almost the same. Instead, the machining program is modified each time, or a machining program is created separately for each. As another method of creating a machining program, there is a method in which a machining program with variables is created first, and actual numerical values are substituted for variables in the machining program to create a final machining program.

[0013]

[0014]

[0015]

In the conventional NC unit, the data of the automatic program is input and output not by a character code which can be easily processed by the external input / output unit 2, but by a special binary code. There is a problem that it is impossible to view data contents on the input / output device 2 unless a dedicated S / W is developed.

Further, automatic program data is generated by an external CAM or the like, and is transmitted from the external input / output device 2 to the NC.
Even if an attempt is made to input data to the device 1, it is necessary to input the data using a special binary code, which is not possible unless a dedicated S / W is developed.

[0017]

[0018] This invention has been made to solve the above problems, and an object thereof is the data of the automatic program, obtain a NC device which enables input and output character code.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Before describing the first embodiment of the present invention, the background art (the input / output of data between the NC device 1 and the external input device 2) in the first embodiment of the present invention will be described. Will be described with reference to FIGS. 1 to 7. FIG. 1 illustrates a process related to data input / output between the NC device 1 and an external input device 2.

The external input / output device 2 generally refers to a paper tape reader (PTR), a paper tape puncher (PTP), a cassette (CMT), a floppy disk drive (FP), etc., and is generally commercially available. You can even use a personal computer. Any other input / output device that can be connected to the NC device may be used. Usually, an I / F such as RS232C is used, but the present invention is not limited to this.

Reference numeral 32 denotes an area in which each data in the NC apparatus 1 is stored, which is usually data stored in the nonvolatile memory 16 in FIG. Reference numeral 33 denotes data managed as a file such as a machining program, which is stored in the nonvolatile memory 16 in the same manner as 32. Numeral 30 denotes a part for controlling the input and output of data between the NC device 1 and the external input / output device 2. The data input / output control unit 30 is connected to a character code conversion processing unit 31. It has a function of converting data other than a character code into a character code, and converting a character code input from an external input / output device 2 into data inside the NC device 1.

The internal data of 32 is N as shown in FIG.
It is stored as array data corresponding to each screen of the C device 1. For example, “TOOL DATA” shown in FIG.
As shown in FIG. 3, it is regarded as array data of 10 rows and 3 columns, and 32 pieces of internal data are stored in a format as shown in FIG. As shown in FIG. 4, each screen data is composed of a header information part and a data part, and the header information part is composed of a screen number, the number of rows and columns of the arrangement of the data part, and the data type.

Although the screen numbers are indicated by the serial numbers of the screens in this description, the screen numbers may be set to numbers corresponding to the screen divisions. For example, if the screen is related to tool information, “T1”, “T2”, “T3”,... Are used as screen numbers, and if the screen is related to parameters, “P1”, “P2”, “P3” ,... Can be used as screen numbers.

In short, the screen number means that information that can specify a screen displayed on the NC apparatus 1 should be provided.

As shown in FIG. 3, the number of rows and the number of columns indicate the number of rows and the number of columns of data displayed on the screen. The value obtained by multiplying the number of rows and the number of columns is the number of data in the data section. Becomes

The data type indicates the type of data stored in the data part. For example, L: double precision real data S: real number data D: double precision integer data N: integer data Is done.

In this description, an example is shown in which all data for one screen is handled as one array data. However, when different types of data are simultaneously displayed on one screen, as shown in FIG. It is also possible to divide the data into half and left halves and divide and store the data into a plurality of array data. In this case, the array indicating the screen number of the left half data is set to “2.1”, and the array indicating the right half data is set to “2.
You may classify it like 2 ".

In FIG. 7, reference numeral 34 denotes display data of the left half displayed on the CRT 19, and reference numeral 35 denotes display data of the right half. Reference numeral 36 denotes array data corresponding to the display data 34 in the left half, and reference numeral 37 denotes array data corresponding to the display data 35 in the right half.

According to the example shown in FIG. 4, (1,1), (1,2), (1,3), (2,1),
(2, 2)... Although an example in which data is stored in the data portion in the order of (2, 2)..., (1, 1), (2, 1),. , (1
0, 2)... May be stored in the data section in the following order.

The "POSITIO" shown in FIG.
If it is difficult to represent the image in an array such as an N ″ screen, it may be stored in a format as shown in FIG. 5 as a one-dimensional array.

Each data is represented by a screen number, a row, and a column. For example, data "55.123" corresponding to # 3, <X> in FIG. 33 is represented as follows. (7,3,1) = 55.123

Here, "7" indicates a screen number, and "3"
Indicates a row number, and “1” indicates a column number.

The array data of FIG. 4 is converted into a character code as shown in FIG. Alternatively, the character codes shown in FIG. 6 are converted to obtain array data as shown in FIG.

In FIG. 6, * H (7, 10, 3), L; indicates header information, and * END; indicates the end of data.

As described above, it is possible to input and output the NC internal data 32 to and from the external input / output device by using the character codes as shown in FIG.

In the above description, the structure of the array data as shown in FIG. 4 is shown, but the data structure is not particularly limited to this.

Embodiment 1 Next, Embodiment 1 of the present invention will be described. Note that the hardware configuration of the numerical control device used in the present invention is the same as that of the conventional one, and a description thereof will be omitted. FIG. 8A is a processing drawing of a workpiece processed on a lathe. The horizontal axis direction is the Z axis, and the vertical axis direction is the X axis. Now, when it is desired to make the lengths of the two portions in the Z-axis direction variable, that is, “L” in FIG.
A procedure for defining the lengths of the portions indicated by A "and" LB "with variables will be described with reference to the flowchart shown in FIG.

First, a machining program is created in the same manner as when a machining program of an ordinary automatic program is created (step 201). FIG. 10 is a screen on which a machining program created from the machining drawing of FIG. 8A is displayed. “Registration”, “printing”, “grouping”, and “variable” displayed at the bottom of the screen are menu displays.

Next, the cursor 46 is moved to a portion to be defined by using a variable, and when the cursor comes to a desired position, the menu "variable" is selected (step 202). Selection of a menu is performed by pressing a menu key provided corresponding to the menu display.

A variable expression is input (step 203). Variable expressions consist of variables, actual numeric values, and operators (+,-, *, /
Etc.). In the example of FIG. 10, "LA" is input at the position of the cursor 46. It is checked whether there is an undefined variable in the input variable expression (step 204). An undefined variable is a variable for which step 205 has not been performed.
Variables that are used many times are undefined only once.

A message is defined for an undefined variable (step 205). Defining a message means defining the message that will be displayed on the screen when defining the value of a variable. When all variables have been defined, the process ends (step 206).

FIG. 11 is a screen display after all the variables have been set in this way, and the parts defined by the variables are highlighted (d1 to d4). The original value becomes the default value of the part defined by each variable.

As shown in FIG. 8B, the length in the Z-axis direction is "L".
When defining by A "and" LB ", d1 to d4 may be set as follows: d1: LA d2; LA d3: LA + 10 d4: LA + LB + 10

When registering a part of the machining program as a variable in this way, the "registration" shown in FIG.
Select a menu. Then, the position of the machining program to be registered is designated by the cursor 46. First, move the cursor 46 to the beginning of the machining program portion to be registered and select “I
Press the "NPUT" key, move the cursor to the end, and press the "INPUT" key to specify the range of the machining program to be registered. The designated part is displayed in reverse video, and when registering, a name is added and registered, and the machining program with variables registered by this name is called.

FIG. 13 is an explanatory diagram showing the data structure registered as described above. t1 is a name added at the time of registration, and indicates that it is defined as "BAR_TP16". t4 is the number of variables used,
Indicates that two variables are used. t5 is the number of locations defined by variables, and indicates that there are portions defined by four variables. t10 is a variable name, "L
Two variables A "and" LB "are used.t11 is message data of each variable, and indicates that a message is added like LA: STEP_1L LB: STEP_2L.

T12, t13, and t14 indicate locations defined by variables, where t12 is a process number,
t13 indicates a sequence number, and t14 indicates a data position counted from the front of one row of data. These are displayed on the screen when creating with the machining program,
In FIG. 12, “PNo.” Is the process number, and “SE”
Q "is a sequence number.

In the example of FIG. 12, the process number is 1, the sequence number is 1 to 3, and the data position is 1 form 2 previous corner 3 start point X 4 start point Z 5 end point X 6 end point Z.

In the example of FIG. 13, the part defined by the variable is 4
Location, which indicates the positions of d1 to d4 in FIG.
Process number Sequence number Data position d1: 116 d2: 124 d3: 126 d4: 133

T15 is a variable expression defined at each location. At t16, the designated portion 64 of the original machining program, that is, the normal machining program before replacement with the variable is stored as it is.

If the operator wants to check the machining program defined by the variables, he selects the "print" menu in FIG. 10 and the registered machining program with variables is printed on the printer as shown in FIG. In the machining program, a part defined by a variable is indicated by (n), and a list of used variables and a variable expression of the part defined by the variable are printed below the part according to (n).

FIGS. 8A and 8B show an example in which only the shape definition part (sequence data) of the machining program is extracted, but in the machining diagram shown in FIG. 37, as shown in FIG. Considering the case where “L1” and “L2” are converted into variables, variables are defined over a plurality of processes as shown in FIG.

FIG. 17 shows the data structure of FIG. FIG.
In the example of No. 6, the variable t1 is set to the name t1 of "TBS7025".
0 “L1” is replaced with the message data t11 of “THR_L”.
Defines the variable t10 “L2” in the message data t11 of “LONG”.

As described above, it is possible to register only a part of the machining program, that is, the sequence data as shown in FIG. 12, or to define and register the entire machining program by variables as shown in FIG. is there.

As shown in FIG. 18, "@ D1", "@D
The value of the 2 "portion is fixed to 5 types for the type to be processed, and if only the portion of" LL "is to be changed each time,"
$ D1 "and" $ D2 "can be grouped and registered.

FIG. 19 shows a machining program in which FIG. 18 is defined by variables. Of the variables, variables with "@" added to the head are group variables. The group variables are variables whose values are determined for each group, and FIG. 20 is a screen for defining the group variables.

The group variables are defined by converting the machining program into variables as shown in FIG. 19 and then selecting the "group" menu in FIG. In FIG. 20, t1
7 is a group variable name, and the group variable to be used is displayed. t18 is a group name, and a group name to be used is input.

In the example of FIG. 20, five groups are defined, and the names and numerical values of each group are TP1: ＠ D1 = 60, ＠ D2 = 5 TP2: ＠ D1 = 70, ＠ D2 = 5 TP3: ＠ D1 = 80 , ＠ D2 = 5 TP4: ＠ D1 = 100, ＠ D2 = 7 TP5: ＠ D1 = 120, ＠ D2 = 8, for example, when the group “TP3” is selected, the variable “
This is equivalent to specifying “$ D1” as 80 and “$ D2” as 5.

As described above, when the set values are fixed for some types, data can be easily set by using this grouping function. FIG. 21 shows the data structure of FIG. 19, where t2 is the number of group variables,
t3 is the number of groups. In the example of FIG. 19, the number of group variables is 2, and the number of groups is 5. t6 is a group variable, t7 is a group name, and t8 is a group variable "＠D
1 ”in each group, and t9 is a group variable“ ＠D
2 "in each group. Others are the same as those described in FIG.

Next, a method of calling a machining program defined using variables will be described. An example of defining the processing in FIG. 18 will be described. FIG. 22 is a screen display when a machining program is defined. By inputting data from the keyboard 21, a normal machining program can be defined, and by programming the machining drawing shown in FIG.
A machining program as shown in FIG.

To call the machining program defined by the variables during the creation of the machining program, select the menu "Call" at the bottom of FIG.

FIG. 23 is a flowchart showing a process for defining a variable-type machining program. First, a program name is input (step 211). It is determined whether or not the specified program exists (step 21).
2) If not, an error is displayed (step 21).
3), end. If the specified program exists, a title corresponding to the specified program is displayed (step 2).
14).

FIG. 24 is an example of a title display, which is a screen display after inputting the program name "TBS7025" and setting each data. The display of "PARAM" means a variable machining program, under which the program name is displayed. In the example of FIG. 19, since the group is defined, "group" for defining the group name is displayed, and the used variable "LL" is displayed.

Next, it is checked whether or not a group has been designated (step 215). If a group has been designated, a group name is selected (step 216). FIG.
4 means that "TP3" has been selected. It is checked whether or not a variable is specified (step 217), and if so, a variable value is input (step 218). When a variable is input, a variable name is displayed on the screen as shown in FIG. 24, and a message corresponding to each variable is displayed on the screen.

For example, when inputting the value of LL, FIG.
Since the message defined at 1 t11 is displayed as "THR_L", it is helpful for the operator to understand what variables are.

When it is desired to check what the variable type machining program looks like, by selecting it from the “shape display” menu shown in FIG. 22, “TB” is selected as shown in FIG.
The graphic display of the shape is performed using the default value of the variable type machining program defined in S7025 ". This makes it possible to easily confirm whether or not the machining pattern is a desired one.

Since the graphic display of the shape can be displayed with the default value without defining the variable value, when calling the variable type machining program, a plurality of variable type machining registered on the screen as an assist function for the operator. A function may be provided in which the shapes of the programs are displayed at the same time, and the operator selects a variable-type machining program from among them.

When the menu of "number display" shown in FIG. 22 is selected, the variable machining program defined in FIG. 24 is displayed after converting the variable portion into the actual value defined. FIG. 26 is an example in which the values defined in FIG. 24 are converted and displayed, and the portion defined by the variables is highlighted.

In this case, only the variable portion is converted into an actual numerical value and displayed. When the “numerize” menu in FIG. 22 is selected, a program converted into the actual numerical value is generated. That is, not only the machining program displayed in FIG. 26 is displayed but also an actual machining program, and a result equivalent to the case where the machining program in FIG. Once converted, the machining program can be edited freely, which is effective when it is desired to modify portions other than those defined by variables.

When the "character output" menu shown in FIG. 22 is selected, the defined machining program is converted into a character code and output. FIG. 27 shows an example of the output of the machining program output in this way, which is obtained by outputting the machining program of FIG.

When inputting / outputting the data of the automatic program, the data is input / output to / from the external input / output device 2 as character data separated by commas for each line of the automatic program as shown in FIG. . The output data is the same as the data displayed on the screen.

"W1100;" indicates a machining program number, and the last "%" indicates the end of data. At the end of the data for each line of the automatic program, a ";" code is added and the data up to this point is one record data.

The process number (P N) shown in FIG.
o. ), The sequence numbers (SEQ) are P1, P
2, P3,... S1, S2, S3,.

Although there is a portion of the data of the automatic program for which data need not be set, only a comma is added to this portion as shown in FIG. When a symbol that cannot be represented by a character code is used by the automatic programmer, for example, a triangular mark indicating surface roughness is substituted with predetermined character data ("Z3").

When the data is not a numerical value but a character, it is assumed that the data is surrounded by "" before and after the data. For example, when indicating “S45C”, it is described as “S45C”.

In the above example, an example of a format in which all data of one line of the automatic program must be output has been described. However, as shown in FIG. 28, the position of each data may be indicated. . In the example of FIG. 28, the number of data in one line of data of the automatic program is indicated by "
＠ ”.

For example, to indicate that the second data is “80.0”, it is sufficient to show ＠ 2 = 80.0.

In this case, unnecessary data can be omitted. For example, among the data of one line of the automatic program, 1,
If only the second, fifth, sixth and ninth data are needed, describe as S1, @ 1 = {LIN}, @ 2 = 5.0, @ 5 = 50.0, @ 6 = 45.0, @ 9 = {Z3}; Is done.

With this method, only the data to be corrected can be specified, so that the data of the automatic program can be processed.

As described above, the data of the automatic program is also stored in the process number t1 as shown in FIG.
2, since the respective data positions can be specified by the sequence number t13 and the data position t14, the format (character code) shown in FIGS. 27 and 28 in the same manner as the processing of the internal data 32 shown in the first embodiment. Allows input and output of machining programs.

As described above, according to the present invention, data of an automatic program can be transferred between an NC unit and an external input / output device in the form of character data which can be easily handled externally, and can be displayed on a screen.
Since input / output can be performed in the order of the displayed data, it becomes easy to manage the data of the automatic program outside the NC device.

Further, data created by an external CAD / CAM system or the like is converted into automatic program data and
It becomes easy to input to the C device.
