Description: TECHNICAL FIELD The present invention relates to a profile data automatic error detection device that automatically detects an error in input data required for the profile control in a profile control device.

(Prior Art) As shown in FIG. 2, the profile control device for performing the profile processing includes X-axis, Y-axis, and Z-axis drive motors 8, 9, 10 so that the stylus 1 moves along the surface of the model 2. And a cutter 5 mechanically coupled to the stylus 1 via the tracer head 3 and the tracer head mounting arm 4,
The work 6 is processed into the same shape as the outer shape of the model 2.

In order to move the stylus 1 along the surface of the model 2 by controlling the X-axis, Y-axis, and Z-axis drive motors 8, 9, and 10, it is necessary to previously store input data necessary for the tracing control. . This input data includes data that must be set according to the copying mode, data that does not need to be set, and data that must not be set. In addition, there are restrictions between data and restrictions on data values. is there.
Conventionally, the operator has to set the profile data with the above conditions always in mind before starting the profile control.

(Problems to be Solved by the Invention) With the progress of the copying technology in recent years, the number of input data necessary for the copying control has increased, and the data conditions have also become complicated. For this reason, it is extremely difficult for the operator to set the data unless he / she remembers all of the above conditions, and it takes a lot of time to set the data.

The present invention automatically checks input data without the operator having to memorize all the conditions for data necessary for copying, and as a result, when the input data is incorrect, the fact is displayed on the display. An error in the data stored in the copying control device is automatically detected, and when no error is found in the copying data, a block program for actually driving the X-axis, Y-axis, and Z-axis driving motors is stored in the data memory. It is an object of the present invention to provide a data automatic error detection device which is to be stored.

(Means for Solving the Problems) The present invention provides a keyboard having an edit end key and an input key for inputting data necessary for copying control, and a task of temporarily storing copying data from the keyboard as a block program. A memory for use, a determination means for sequentially checking the copy data in the block program and determining whether or not the input data is data of a copy mode or copy function, and a copy mode of the input data. Check means for checking whether simultaneous setting of copying mode data and copying function data is possible when the data is data, and automatically detect data error when input data is data other than copying mode and copying function data Detection means that the setting of the checked data Display means for displaying a message according to the type and type of error;
A data memory for storing a block program to be transferred after being corrected from the working memory.

(Operation) That is, in the automatic data error detection device according to the present invention,
By automatically checking the data entered from the keyboard and displaying a message corresponding to the error of the copied data and the type of the checked data and the type of the error on the display, the labor of the operator can be reduced, and the operator's labor can be reduced. Highly reliable data required for tracing can be created.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a system configuration diagram showing one embodiment of the present invention.

20 is an arithmetic processing means such as a microprocessor (CP
U), 21 is a keyboard for inputting data and the like necessary for copying control, 23 is a numeric keypad of the keyboard 21,
Reference numeral 24 denotes a function key portion of the keyboard 21, and the function key portion 24 includes an input key 30, an edit end key
There are 31 and so on. Reference numeral 22 denotes a display for displaying input data from the keyboard 21 and for displaying an error when there is an error in the input data.

FIG. 7 shows a specific example of the display screen of the display 22.

On this display screen, a code area 44 for displaying a code obtained by coding the data type of the block and an area 46 for displaying a data name corresponding to the code are always displayed. The data content area 48 is an area for displaying data input from the keyboard 21 according to its type. In addition to these areas 44, 46, and 48, a non-storable content display area
There is a 40 and a non-storable number display area 42, and when there is an error in the input data, the type of data error, for example,
“Data shortage”, “simultaneous setting impossible”, and the like are displayed in the non-storable content display area 40, and the corresponding data code is displayed in the non-storable number display area 42.

Referring again to FIG. 1, reference numeral 25 denotes data necessary for copying control, that is, a data memory for storing a block program, and 26 denotes a work memory, which is data input from the keyboard 21, that is, one block of the block program. Is temporarily stored to check the data, or the calculation result of the processor 20 is temporarily stored. Reference numeral 27 denotes a program memory which checks data necessary for control following the input from the keyboard 21 and, when an error is detected, a program for displaying the fact on the display 22 or stored in the data memory 25. Based on the data, programs for controlling the X-axis, Y-axis, and Z-axis drive motors 8, 9, and 10 are stored. Reference numeral 28 denotes a drive motor control signal generation circuit which generates motor control signals for controlling the X-axis, Y-axis, and Z-axis drive motors 8, 9, and 10 based on the data stored in the data memory 25.

FIG. 3 is a diagram showing data to be stored in the data memory 25, that is, a format of a block program. Data necessary for the profile control is divided into one block per one processing step, and block numbers 01, 02. The contents of data set in one block include block number N, positioning command X,
Y, Z, copying limits ± X, ± Y, copying mode, function A, function B, function C, and the like.

Here, the positioning commands X, Y, and Z are position commands for any of the X, Y, and Z axes. In addition, copying limits ± X,
± Y is data for determining the limit value in the X-axis and Y-axis directions of the area to be profiled.

The tracing mode is a mode for determining the method of tracing processing, and is unselected, reciprocating on the surface, tracing the surface in one direction, tracing the entire circumference of the contour, tracing the contour part,
There are types such as three-dimensional copying.

When the copying mode is unselected, only the positioning command is issued, and "unselected" is set when only the positioning command is issued. “Surface reciprocation copying” is set when the stylus 1 is reciprocated on the surface of the model 2 to perform the stitching.
Is set in the case where is moved in one direction to the surface of the model 2 for processing. Further, "contour all around contour" is set when the stylus 1 is moved over the entire periphery of the contour of the model 2 for machining, and "contour contour" is used to move the stylus 1 over a part of the contour of the model 2. This is set when processing is performed. “Three-dimensional copying” is set when machining is performed by moving the stylus 1 in an arbitrary direction programmed in advance.

In order to perform any one of these copying modes, a copying pattern of function A, function B, and function C is set.

The function A includes a plurality of functions such as all-surface cutting and one-pass tracing, and one of the plurality of functions is selected and set. Function B is like horseshoe shape, fixed angle,
It consists of a plurality of functions such as arbitrary directions, and one of these functions is selected and set. Function C is
It consists of a plurality of functions such as a rotating body, and one of these functions is selected and set.

In the function A, the function of "all face cutting" means that the cutting feed is performed within the plane (± X, ± Y, ± Z) designated by the positioning command X, Y, Z as shown in FIG. This function is effective only when the copying mode is “unselected”. In this case, the XYZ positioning speed is fast forward.

The “one-pass copying” is a function that performs a copying operation from a copying start to a sequence change due to a limit or the like and ends the copying. This function is a copying mode “surface reciprocating”, “surface one-way”, “ Contour all around ”,
This is effective for "outline part". In the case of the contour all around, as shown in FIG. 4 (b), start from above the limit, complete one round, and end when stepping on the limit.

In function B, the horseshoe profile is a function that checks the number of limits (X, Y) set at the start of the trace, automatically determines the operation pattern, and performs the horseshoe profile. This is effective in partial copying mode. FIGS. 4 (c) and 4 (d) show the operations when one limit is set and when two limits are set, respectively. The constant angle tracing is a function of tracing in the direction of the angle α as shown in FIG. 4 (e) by setting the position of the start point, the position of the target body, and the position of the tracing end point. This is effective in the reciprocating mode on the surface and in the unidirectional mode on the surface. In any direction,
This is a function that allows the user to follow an arbitrary direction programmed in advance, and is effective in the three-dimensional copying mode.

In the function C, the rotating body is a function in which one rotating shaft is used, and is effective in the mode of reciprocating the surface, one direction of the surface, the entire circumference of the contour, and the contour portion.

These functions A, B, and C are classified into basic functions and additional functions.

FIG. 5A shows the relationship between the copying mode and the functions A, B, and C as described above, and FIG. 5B shows the relationship between the functions A, B, and C.

In FIGS. 5A and 5B, ““ ”indicates a selectable item, and“ × ”indicates an unselectable item.
For example, in FIG. 5 (a), when the surface reciprocating mode is selected, one pass of function A, the following of clamp, the arbitrary angle of function B, the constant angle, the function C
In this case, only the rotating body and the prohibited area can be selected, and the function A cannot be selected. Therefore, as shown in FIG. 5 (b), for example, it is possible to simultaneously select and set one pass of function A and a horseshoe shape of function B.
Cannot be set at the same time as the arbitrary direction.

When creating data in a block, check whether the input data is data that can be set, that is, check whether there is insufficient data, and set the following limits ± X, ± Y Whether the value of + X limit -X limit, the value of + Y limit and -Y limit are not reversed, or the value of + X limit and -X limit, or the value of + Y limit and -Y limit Check if they are not approaching, and as described above, whether or not the selection conditions for the copying mode and functions A, B, and C are satisfied, or whether the selection conditions between functions A, B, and C are satisfied. It is necessary to check whether or not there is.

Hereinafter, the input data in the working memory is checked as described above, and as a result of the check, if there is an error in the input data, the fact is displayed on the display, and when all the checks are completed, the data is created in the working memory. An embodiment of the method of the present invention for storing the input data obtained in the data memory will now be described.

FIG. 6 shows a flow chart for implementing the method of the present invention.

In FIG. 6, in a step, an operator inputs data from the keyboard 21 to the working memory 26. At the same time, the input data is displayed in the data content area 48 of the display 22 according to the data type (step). Next, it is determined whether or not the input key 30 has been pressed (step). When the input key 30 is not pressed, the process returns to the step again, and the same kind of data can be further input from the keyboard 21. When the input key 30 is pressed, the operation proceeds to the step.

In the step, it is determined whether or not the type of the data just input is block number data. If the input data is block number data, it is checked whether the data is insufficient (step). It is determined whether or not the data is insufficient (step).
As shown in FIG. 7A, a message of "data shortage" is displayed in a non-storable content display area 40 of the display screen of the display, and at the same time, a data code, in this example, a block number code "001" is displayed in a non-storable number display area 42. Is displayed (step), and the process proceeds to the step. If not, go directly to the step.

In the step, if the input data is not the block number data, the input data is in the copying mode or the function A,
It is determined whether the data is B and C data (step). If the input data is data in the copying mode or the functions A, B, and C, it is checked whether or not simultaneous setting of these data is possible (step). It is determined whether simultaneous setting is impossible (step). If simultaneous setting is not possible, a message "simultaneous setting impossible" is displayed in the storage impossible content display area 40 of the display 22 as shown in FIG. 8B. Is displayed in the non-storable number display area 42, as shown in FIG. 8 (b), and the code "015" of the copying mode and the code "100" of the function A are displayed (step). Thereby, it is possible to inform the operator that the simultaneous setting of the copying mode and the function A is not appropriate. After displaying on the display 22, the process proceeds to the step. If it is determined in step that simultaneous setting is not possible, the process proceeds to step.

If the input data is not the copying mode or the function A, B, C data in the step, the other data of the block, for example, the positioning command, etc. are checked, and after these checks are completed, the process proceeds to the step.

In the step, it is determined whether or not the content that cannot be stored at the time of input has been cleared, that is, whether or not the input data has no error. If the contents that cannot be stored at the time of input have not been cleared, the process returns to the step again to correct the data. Note that in this embodiment, during the steps and
Even if the editing end key 31 is pressed, no interruption by this key occurs. That is, even if the editing end key is pressed, it is not accepted. However, as a modified example, a step of receiving an editing end key is provided in the middle of the steps to make the display in the non-storable number display area 42 of the display 22 different from the timing of displaying in the non-storable content display area 40, for example. Can also.

When the contents that cannot be stored at the time of input are cleared in the step, the process proceeds to the step, and it is determined whether or not the edit end key 31 is pressed. When the edit end key 31 is pressed, a limit reverse rotation check is performed (step). It is determined whether or not the copying limit is reversed (step), and if so, a message of "limit reversed" is displayed in the non-storable content display area 40 of the display 22 as shown in FIG. 8 (c). Is displayed, and at the same time, a non-storable number, that is, a data code, is displayed in the non-storable number area (step). In the example shown in FIG. 8 (c), the + X following limit code "005" and the -X following limit code "006" are displayed, whereby the operator can set the + X following limit and the -X following limit. Can be notified that is reversed. After completing the steps,
Returning to the step, the data of the copying limit can be corrected.

If the copying limit is not reversed in the step, a limit approach check is performed (step). It is determined whether or not the copying limit is approaching (step), and when it is approaching, a "limit approaching" message is displayed in the non-storable content display area 40 of the display as shown in FIG. 8 (d). Is displayed, and at the same time, a non-storable number, that is, a data code, is displayed in a non-storable number display area (step). In the example shown in FIG. 8 (d), the + Y following limit code "007" and the -Y following limit code "008" are displayed, whereby the operator can set the + Y following limit and the -Y following limit. You can know that you are approaching. When the step is completed, the process returns to the step and the data of the copying limit can be corrected.

In the step, when the limit is not approaching, all the checks are completed, the input data in one block is in an error-free state, and the data of one block created in the working memory 26 is deleted. The data is transferred to and stored in the data memory 25 (step).

After the blocks are successively stored in the data memory 25 in this manner, X is stored in accordance with these block programs.
The axis, Y-axis, and Z-axis drive motors 8, 9, and 10 can be actually driven.

(Effects of the Invention) As described above, according to the present invention, a plurality of data are set to execute a certain operation, a desired operation is realized by a combination of these data, and a check of input data is performed. Checks not only the data itself but also the excess and deficiency of data for performing the operation and the interrelationships.If the data is incorrect, the fact is displayed on the display, and the input data of the copying control device is displayed. Automatically detects errors and displays a message according to the type of data checked and the type of error, significantly reducing operator effort, reducing data setting errors, and if a setting error occurs However, the correction can be made quickly, which makes the block program stored in the data memory extremely reliable. In addition, it is possible to provide a data automatic error detection method which ensures operation of the copying control device and further guarantees safe operation.
