The present invention relates to a shape defining method in a numerical control information creating function.

(Prior Art) The shape definition method in the conventional numerical control information creation function is
This has been done by deleting the already defined shape itself, changing the data, and adding a new shape.

Hereinafter, a shape defining method in the conventional numerical control information creating function will be described with reference to the drawings.

FIG. 6 is a block diagram showing a shape defining method in the conventional numerical control information creating function.

Conventionally, a shape data input unit 2 for inputting shape data SA from a keyboard 1 to calculate a defined shape, a defined shape storage unit 3 for storing a defined shape SB output by the shape data input unit 2, and a defined shape storage unit Machining path generation unit 4 for extracting machining path generation shape data SC from 3 and generating trajectory data
And a machining path data storage unit 5 that stores the machining path data SD output by the machining path generation unit 4. The machining path data stored in the machining path data storage unit 5 is used for creating a numerical control program and for operating a numerically controlled machine.

FIG. 7 shows the procedure of the shape defining method in the conventional numerical control information creating function.

If the operator tries to modify the defined shape,
First, it is determined whether or not an unnecessary shape is included in the defined shapes (step S1), and if it is included, all the shapes are deleted (step S2), and then the process proceeds to step S3. On the other hand, if there is no unnecessary shape in step S1, the process directly proceeds to step S3. In step S3, the operator or the like determines whether or not it is necessary to change the data in the defined shape, and if there is, changes all the data of the shape (step S4), and then shifts to step S5. On the other hand, if it is determined in step S3 that there is no need to change the data among the defined shapes, the process directly proceeds to step S5. In step S5, the operator or the like determines whether or not it is necessary to add a shape to the defined shape, and if it is necessary, adds all the shapes (step S6) and ends the processing. On the other hand, if it is determined in step S6 that there is no shape that needs to be added, the process ends.

FIG. 8 shows a specific example in which the shape defining method in the conventional numerical control information creating function is implemented. In this case, the line segments 6,7,8,
Shape the shape consisting of 9,10,11 into line segments 6,7 ', 10', 11,12,13
It is to be modified into a shape composed of.

Explaining this example based on the above procedure, first, it is determined whether there is an unnecessary shape (step S1),
It is determined that line segment 8 and line segment 9 are unnecessary, and line segment 8 and line segment 9
Is deleted (step S2), and a shape composed of line segments 6, 7, 10, and 11 is obtained. Next, it is determined whether there is a shape that needs to be changed (step S3), it is determined that the line segment 7 and the line segment 10 need to be changed, and the end point of the line segment 7 and the start point of the line segment 10 are changed (step S3).
S4), and obtain a shape composed of line segments 6, 7 ', 10' and 11. Finally, in step S5, it is determined that the line segment 12 and the line segment 13 are necessary, and this is added (step S6), and the line segments 6, 7 ', 12, 13,
Get the shape consisting of 10 ', 11.

Conventionally, the defined shape is corrected as described above.

(Problems to be solved by the invention) However, in the above-described shape defining method in the numerical control information creating function, in order to make a correction, the shape data of which part is deleted, the shape data of which part is changed, and The operator had to decide for himself whether to add such shape data. Further, not only the correction operation cannot be performed while referring to the already defined shape, but also the shape calculation is repeated each time the correction operation is performed, so that unnecessary portions are deleted, the shape data is corrected, and necessary. Until the addition of such a shape was completed, the operator was presented with an abnormal shape, which confused the operation.

The present invention has been made under the circumstances as described above, and an object of the present invention is to release the operator from the thought and complicated operation for deleting and changing a part of the defined shape, and before the correction. Numerical control information creation that makes it possible to easily modify defined shapes by enabling operations while referring to shapes and not presenting abnormal shapes to the operator during correction operations It is to provide a shape definition method in the function.

(Means for Solving the Problem) The present invention relates to a shape defining method capable of easily modifying a defined shape in a numerical control information creating function for creating a numerical control program or a command for operating a numerically controlled machine. The object of the present invention is, in the shape defining method in the numerical control information creating function, when a defined shape is modified, a shape that is different between the shape before modification and the shape to be obtained after modification is defined. After the definition, if the start point and end point of the defined difference shape are on the shape before correction, the part between the start and end points of the defined difference shape of the shape before correction If the start point of the shape that has been deleted and has a defined difference is on the shape before correction, it is sandwiched between the start point of the shape that has a defined difference and the end point of the shape before correction of the shape before correction. Erase the part, If the end point of the defined difference shape is above the uncorrected shape, erase the part between the end point of the defined difference shape and the start point of the uncorrected shape in the uncorrected shape. This is achieved by making a defined shape modification.

(Operation) In the present invention, when modifying a defined shape, after defining a shape that is different between the shape before modification and the shape that should be obtained after modification, If the start point and the end point are on the shape before correction, the part between the start point and the end point of the shape that makes the defined difference in the shape before correction is deleted, and the start point of the shape that makes the defined difference If is on the shape before correction, erase the part between the start point of the shape with the defined difference, the start point of the shape before correction, and the end point of the shape before correction of the shape before correction. , If the end point of the defined difference shape is above the shape before correction, the part between the end point of the defined shape and the start point of the shape before correction in the shape before correction By erasing, the defined shape can be easily modified.

(Example) Hereinafter, the Example of this invention is described in detail based on drawing.

FIG. 1 is a block diagram for realizing the shape defining method in the numerical control information creating function of the present invention. The same parts as in the conventional art are designated by the same reference numerals and the description thereof will be omitted.

In the method of the present invention, a corrected shape storage section and a defined shape correction section are newly provided.

The shape data input unit 2 receives the shape data SA from the keyboard 1.
The definition shape data SB and the correction shape data SE are input as, and the definition shape and the correction shape are calculated. The corrected shape data SE from the shape data input unit 2 is temporarily stored in the corrected shape storage unit 12. Further, the defined shape correction unit 13 takes out the correction target defined shape data SG from the defined shape storage unit 3, while taking out the corrected shape data SF from the corrected shape storage unit 12,
The corrected shape data SH is created and output to the defined shape storage unit 3 again.

FIG. 2 is a diagram showing a procedure of a shape defining method in the numerical control information creating function of the present invention.

Explaining the procedure based on FIG. 2, the operator first determines a correction start point or a new start point (step S
7). At this time, the correction start point is the point where a difference begins to occur between the defined shape and the shape that will be obtained after the correction, and it is set on the line when correction is performed without including the start point of the defined shape. , A new starting point is defined when modifying it including the defined starting point. The correction start is also the starting point of the different shape. Next, a correction end point or a new end point is determined (step S8). At this time, the modification end point is the point where there is no difference between the defined shape and the shape that will be obtained after modification, and is set on the line when modifying without including the end point of the defined shape. , A new end point is defined when modifying including a defined end point. The correction end point is also the end point of the different shape.

Next, define the shape to connect the modification start point or new start point and the modification end point or new end point with a line (step
S9), after the definition is completed, an instruction is given to erase unnecessary parts (step S10). By this, the shape sandwiched between the modification start point and the modification end point of the defined shape, or, if a new start point is defined, the shape sandwiched between the start point and the modification end point of the defined shape, Alternatively, when a new end point is defined, the shape sandwiched between the correction start point and the end point among the defined shapes is deleted, and as a result, the shape desired by the operator can be defined.

FIG. 3 shows a first specific example in which the shape defining method in the numerical control information creating function of the present invention is implemented. In this case, the shape consisting of line segments 14,15,16,17,18,19 is
The shape is modified to consist of 5 ', 20, 21, 18', and 19.

To explain this specific example based on the above procedure,
First, the correction start point is set on the line segment 15 (step S7), and then the correction end point is set on the line segment 18 (step S8). Next, the line segments 20 and 21 that connect the correction start point and the correction end point are defined (step S9), and then an instruction is issued to erase unnecessary portions of the defined shape (step S10). As a result, part of the line segment 15 between the correction start point and the correction end point, the line segment
Part of 18 and line segments 16 and 17 are automatically deleted, resulting in a shape consisting of line segments 14, 15, 20, 21, 18 'and 19.

Note that step S8 does not necessarily have to be performed before step S9, and even if step S8 is performed after step S9 is performed, the effect does not change. For example, in the method of sequentially inputting connection points of shapes and simultaneously inputting the connection relationship between the points, in the case of FIG. 3, a correction start point is designated (step S7), the coordinate values thereof are input, and Enter the "right horizontal line segment" as the connection relationship. Next, specify the connection points of line segment 20 and line segment 21 as connection points and enter the coordinate values,
Enter "bottom right line" as the connection relationship with the following. The connection shape is defined by such a procedure (step S9), the correction end point is designated at the end, the coordinate values are input (step S8), and the process ends. As a result, the same result as when executing step S8 before step S9 is obtained.

FIG. 4 shows a second specific example in which the shape defining method in the numerical control information creating function of the present invention is implemented. In this case, the shape consisting of line segments 14,15,16,17,18,19 is converted into line segments 22,23,1
The shape is modified to consist of 6 ', 17, 18, and 19.

To explain this specific example based on the above procedure,
First, a new starting point is determined (step S7). At this time, it is not necessary to set it on the line of the defined shape. Next, the correction end point is set on the defined shape (step S8), and the line segments 22 and 23 connecting the new start point and the correction end point are defined (step S8).
9) Then, an instruction is issued to erase the unnecessary portion of the defined shape (step S10). As a result, the line segments 14, 15 and part of the line segment 16 sandwiched between the start point and the correction end point in the defined shape are automatically deleted, and as a result, the line segments 22, 23, 16 ', 17, 1
A shape consisting of 8,19 is obtained. In this case, too,
Similar results can be obtained by performing step S9 prior to step S8.

FIG. 5 shows a third specific example in which the shape defining method in the numerical control information creating function of the present invention is implemented. In this case, the shape consisting of line segments 14,15,16,17,18,19 is converted into line segments 14,15,1
The shape is modified to consist of 6 ″, 24, 25, 26.

To explain this specific example based on the above procedure,
First, set the correction start point on the line of the defined shape (step
Then, a new end point is determined (step S8). next,
A line segment 24, 25, 26 that connects the correction start point and the new end point is defined (step S9), and then an instruction is issued to erase unnecessary portions of the defined shape (step S10). As a result, a part of the line segment between the correction start point and the end point and the line segments 17, 18 and 19 with the defined shape are automatically deleted, resulting in the line segment 14, 15,
A shape composed of 16 ″, 24, 25, 26 can be obtained. In this case, of course, the same result can be obtained by performing step S9 prior to step S8.

(Effects of the Invention) As described above, according to the shape defining method in the numerical control information creating function of the present invention, it is possible to easily modify a defined shape, and refer to the defined shape during the modification. Since it is possible to perform a correction operation while doing so, it is extremely useful in practice.
