At 56, information on the curved surface 56a on the inner peripheral side is acquired. The curved surface 56a is an example of a bent surface.

In this configuration, when the three-dimensional data of the bracket 50 is uploaded to a predetermined portion of the information processing apparatus 30, the information acquisition unit 302 uses the three-dimensional data to provide information on the burrings 58 and 60 and information on the end face 50a. , And the information of the curved surface 56a is acquired. Specifically, the information acquisition unit 302 acquires relative position information between the burring 58 and the burring 60 from the three-dimensional data. Further, the information acquisition unit 302 acquires the position information of the end surface 50a with respect to the burring 58 and 60 and the position information of the curved surface 56a with respect to the burring 58 and 60. In this way, the information acquisition unit 302 functions as a position information acquisition means.

− Derivation unit 304−
The lead-out unit 304 derives the distance along the plate surface of the base 52 from the burring 58, 60 to the end surface 50a, and the distance along the plate surface of the base 52 from the burring 58, 60 to the curved surface 56a. Further, the lead-out unit 304 derives the distance from the burring 58 to the outer peripheral surface 60a of the burring 60 and the distance from the burring 60 to the outer peripheral surface 58a of the burring 58. When the burring 58 is an example of one processed portion, the burring 60 is an example of another processed portion, and when the burring 60 is an example of one processed portion, the burring 58 is an example of the other processed portion. This is an example. Further, the end surface 50a and the curved surface 56a are examples of other processed portions.

-Judgment unit 306-
The determination unit 306 determines whether or not the distance derived by the extraction unit 304 is equal to or greater than a predetermined reference value. The reference value is stored in the ROM 34. In other words, the determination unit 306 selects a distance less than the reference value from the plurality of distances derived by the out-licensing unit 304.

-Display unit 308-
The display unit 308 displays the determination result by the determination unit 306 on the screen 112 together with the shape of the bracket 50 based on the three-dimensional data.

Specifically, the display unit 308 displays the determination items determined by the determination unit 306 on the screen 112, and determines whether or not the distance is equal to or greater than a predetermined reference value on the screen 112 with different colors of the determination items. Display (see FIG. 1). More specifically, the display unit 308 displays on the screen 112 with different colors of the determination items depending on the degree to which the distance does not satisfy the reference value. In other words, the display unit 308 displays on the screen 112 whether or not the distance is equal to or greater than a predetermined reference value in different display methods depending on the degree to which the distance does not satisfy the reference value. The "degree of distance not satisfying the reference value" is derived by comparing the absolute values away from the reference value.

Further, when the distance is less than a predetermined reference value, the display unit 308 displays a mark indicating a portion less than the reference value on the shape of the bracket 50 displayed on the screen 112. Specifically, the display unit 308 displays a line connecting one processed portion and another processed portion corresponding to a portion less than the reference value on the product shape based on the three-dimensional data of the screen 112 as a mark. Further, the display unit 308 displays on the product shape based on the three-dimensional data by changing the thickness of the line depending on the degree to which the distance does not satisfy the reference value.

First, the process in which the information processing device 30 acquires the information of the burring 58 and 60 from the three-dimensional data will be described using the flow chart of FIG. 7, and then the information processing device 30 uses the shape of the bracket 50 as a reference. The process of determining whether or not the user is satisfied will be described with reference to the flow chart of FIG.

[Step of acquiring information on burring 58 and 60]
When the user uploads the three-dimensional data of the bracket 50 to a predetermined portion of the information processing apparatus 30, in step S100 shown in FIG. 7, the information acquisition unit 302 obtains the plate thickness information of the bracket 50 from the three-dimensional data. get.

Next, in step S200, the information acquisition unit 302 determines whether or not the bracket 50 has an inner peripheral surface having a height of 1.5 times or more the plate thickness. Here, the "inner peripheral surface" is a surface orthogonal to the plate surface of the plate material (in the present embodiment, the plate surface of the base 52), and is a surface that is connected once and faces inward.

In the present embodiment, the inner peripheral surfaces 58b and 60b of the burrings 58 and 60 have a height of 1.5 times or more the plate thickness and a base portion as shown in FIGS. 3 and 4A and 4B. It is a surface orthogonal to the plate surface of 52, and is a surface that is connected once and faces inward. Therefore, the information acquisition unit 302 determines that the bracket 50 is formed with inner peripheral surfaces 58b and 60b having a height of 1.5 times or more the plate thickness.

When the inner peripheral surface is formed, the process proceeds to step S300, and when the above-mentioned requirements are not satisfied, the work is terminated.

Next, in step S300, the information acquisition unit 302 determines whether or not the inner peripheral surfaces 58b and 60b are composed of one curved surface or two curved surfaces and two planes. In the present embodiment, the inner peripheral surface 58b is composed of one curved surface as shown in FIG. 4 (A). The inner peripheral surface 60b is composed of two curved surfaces 62a facing in the depth direction and two flat surfaces 62b facing each other in the width direction. Therefore, the information acquisition unit 302 determines that the inner peripheral surface 58b is composed of one curved surface, and the inner peripheral surface 60b is composed of two curved surfaces and two planes.

When the inner peripheral surfaces 58b and 60b are composed of one curved surface or two curved surfaces and two planes, the process proceeds to step S400, and when the above-mentioned requirements are not satisfied, the work is completed. To do.

Next, in step S400, the information acquisition unit 302 determines whether or not a torus surface surrounded by two ridges or an oval ring surface is formed at the tips of the inner peripheral surfaces 58b and 60b. .. In the present embodiment, as shown in FIGS. 3 and 4A, a torus surface 58c surrounded by two ridges is formed at the tip of the inner peripheral surface 58b. Further, an oval ring surface 60c surrounded by two ridges is formed at the tip of the inner peripheral surface 60b. Therefore, the information acquisition unit 302 determines that the torus surface 58c or the torus surface 60c surrounded by the two ridges is formed at the tips of the inner peripheral surfaces 58b and 60b.

When a ring surface surrounded by two ridges or an oval ring surface is formed at the tips of the inner peripheral surfaces 58b and 60b, the process proceeds to step S500, and when the above-mentioned requirements are not satisfied. Finish the work.

Next, in step S500, the information acquisition unit 302 determines whether or not an outer peripheral surface extending in the height direction is formed on the outside of the torus surface 58c or the torus surface 60c. Here, the "outer peripheral surface" is a surface orthogonal to the plate surface of the plate material (in the present embodiment, the plate surface of the base 52), and is a surface that is connected once and faces outward.

In the present embodiment, the outer peripheral surfaces 58a and 60a of the burrings 58 and 60 are connected once on a surface orthogonal to the plate surface of the base 52 as shown in FIGS. 3 and 4A. It faces outward. Therefore, the information acquisition unit 302 determines that the outer peripheral surfaces 58a and 60a that are orthogonal to the plate surface of the base portion 52 and that are connected once and face outward are formed.

When the outer peripheral surface is formed, the process proceeds to step S600, and when the above-mentioned requirements are not satisfied, the work is terminated.

In step S600, the information acquisition unit 302 recognizes the burring 58 as the circular hole burring and the burring 60 as the long hole burring, and ends a series of operations.

[Step of determining whether the shape of the bracket 50 satisfies the standard]
Next, a step of determining whether or not the shape of the bracket 50 satisfies the standard will be described. Specifically, a step of determining whether or not the burrings 58 and 60 recognized in the above-mentioned steps are formed at positions satisfying the reference will be described. More specifically, a step of determining whether or not the distance from the burring 58 to the outer peripheral surface 60a of the burring 60 and the distance from the burring 60 to the outer peripheral surface 58a of the burring 58 is equal to or greater than the reference value will be described. Further, a step of determining whether or not the distance from the burring 58, 60 to the end face 50a and the distance from the burring 58, 60 to the curved surface 56a is equal to or greater than the reference value will be described.

First, in step T100 shown in FIG. 8, the information acquisition unit 302 acquires the first adjacent surfaces adjacent to the outer peripheral surfaces 58a and 60a of the burrings 58 and 60, respectively. In the present embodiment, as shown in FIGS. 3 and 4A, the information acquisition unit 302 first adjacents one plate surface 52a of the base 52 adjacent to the outer peripheral surfaces 58a and 60a of the burrings 58 and 60. Get as a face.

Next, in step T200, the information acquisition unit 302 acquires a second adjacent surface adjacent to the plate surface 52a. In the present embodiment, as shown in FIGS. 3 and 4A, the information acquisition unit 302 is adjacent to the outer peripheral surfaces 58a and 60a of the burrings 58 and 60 adjacent to the plate surface 52a and adjacent to the plate surface 52a. The end surface 50a of the bracket 50 and the curved surface 56a of the connecting portion 56 adjacent to the plate surface 52a are acquired as the second adjacent surfaces.

Next, in step T300, the information acquisition unit 302 determines whether or not the outer peripheral surfaces 58a and 60a of the burring determined in step S500 of FIG. 7 are acquired as the second adjacent surfaces in step T200. In the present embodiment, since the outer peripheral surfaces 58a and 60a of the burring are acquired, the process proceeds to step T400. If the outer peripheral surface of the burring has not been acquired, the process proceeds to step T410.

Next, in step T400, the information acquisition unit 302 recognizes the outer peripheral surfaces 58a and 60a as the second adjacent surfaces to be determined.

Next, in step T500, the lead-out unit 304 derives the distance L01 from the burring 58 to the outer peripheral surface 60a which is the second adjacent surface, and the distance L02 from the burring 60 to the outer peripheral surface 58a which is the second adjacent surface ( (See Fig. 2). Further, the determination unit 306 determines whether or not the distances L01 and L02 are equal to or greater than a predetermined reference value. The distances L01 and L02 need to satisfy the reference values or more in order to ensure the positional accuracy of the burrings 58 and 60 processed in the punching process described above. More specifically, this is to secure a flat surface for pressing the base 52 when the burrings 58 and 60 are processed in the punching process described above.

Next, in step T600, the display unit 308 displays the determination result by the determination unit 306 on the screen 112 together with the product shape based on the three-dimensional data. Specifically, the display unit 308 displays the product shape based on the three-dimensional data on the right side portion of the screen 112 shown in FIG. 1, and displays the determination result table on the left side portion. In the judgment result table, the judgment items, the reference value for the judgment item, and the number of NG points that do not satisfy the reference value are described.

In the present embodiment, since the distances L01 and L02 are equal to or larger than the reference value, the display unit 308 displays the determination item column described as "burring to burring" in green. Further, the display unit 308 displays the number of NG points as “0” for the distance from burring to burring. The green color is shown in white in the figure.

On the other hand, when the distance derived by the derivation unit 304 is less than the reference value, the display unit 308 displays the number of NG points in the determination result table and displays the NG points on the product shape based on the three-dimensional data.

Next, in step T700, the information acquisition unit 302 determines whether or not another second adjacent surface has been acquired. Specifically, the information acquisition unit 302 determines whether or not the second adjacent surface has been acquired in addition to the second adjacent surface that has already been determined. In the present embodiment, in addition to the outer peripheral surfaces 58a and 60a of the burrings 58 and 60, the end surface 50a and the curved surface 56a are acquired as the second adjacent surfaces. Therefore, the process proceeds to step T410. If the second adjacent surface has not been acquired in addition to the second adjacent surface that has already been determined, the series of operations is completed.

When shifting from step T700 to step T410, or when shifting from step T300 to step T410, in step T410, the information acquisition unit 302 constitutes the end face 50a acquired as the second adjacent surface and one edge facing the other. It is determined whether or not the shortest distance from the to the other edge is the same as the plate thickness of the bracket 50. Further, the information acquisition unit 302 constitutes the curved surface 56a acquired as the second adjacent surface, and determines whether or not the shortest distance from one opposite edge to the other edge is the same as the plate thickness of the bracket 50. ..

In the present embodiment, the shortest distance from one edge facing the end face 50a to the other edge is the same as the plate thickness of the bracket 50. Therefore, the process proceeds to step T450. If the shortest distance from one edge to the other edge does not acquire the same second adjacent surface as the plate thickness of the bracket 50, the process proceeds to step T460.

In step T450, the information acquisition unit 302 recognizes the end surface 50a as the second adjacent surface to be determined, and in step T500, the out-licensing unit 304 has the distance L03 from the burring 58 to the end surface 50a which is the second adjacent surface, and The distance L04 from the burring 60 to the end face 50a, which is the second adjacent surface, is derived (see FIG. 2). Further, the determination unit 306 determines whether or not the distances L03 and L04 are equal to or greater than a predetermined reference value. The distances L03 and L04 need to satisfy the reference values or more in order to ensure the positional accuracy of the burrings 58 and 60 processed in the punching process described above. More specifically, this is to secure a flat surface for pressing the base 52 when the burrings 58 and 60 are processed in the punching process described above.

Next, in step T600, the display unit 308 displays the determination result by the determination unit 306 on the screen 112 together with the product shape based on the three-dimensional data.

Next, in step T700, the information acquisition unit 302 determines whether or not another second adjacent surface has been acquired. Specifically, the information acquisition unit 302 determines whether or not the second adjacent surface has been acquired in addition to the second adjacent surface that has already been determined. In the present embodiment, in addition to the outer peripheral surfaces 58a and 60a and the end surface 50a, a curved surface 56a is acquired as a second adjacent surface. Therefore, the process proceeds to step T410. If the second adjacent surface has not been acquired in addition to the second adjacent surface that has already been determined, the series of operations is completed.

When shifting from step T700 to step T410, or when shifting from step T300 to step T410, in step T410, the information acquisition unit 302 constitutes and faces the curved surface 56a acquired as the second adjacent surface. It is determined whether or not the shortest distance from one edge to the other edge is the same as the plate thickness of the bracket 50.

In the present embodiment, the shortest distance from one edge facing the curved surface 56a to the other edge is different from the plate thickness of the bracket 50. Therefore, the process proceeds to step T460.

In step T460, the information acquisition unit 302 recognizes the curved surface 56a as the second adjacent surface to be determined, and in step T500, the out-licensing unit 304 is the distance L05 from the burring 58 to the curved surface 56a which is the second adjacent surface. , And the distance L06 from the burring 60 to the curved surface 56a, which is the second adjacent surface, is derived (see FIG. 2). Further, the determination unit 306 determines whether or not the distances L05 and L06 are equal to or greater than a predetermined reference value. The distances L03 and L04 need to satisfy the reference values or more in order to ensure the positional accuracy of the burrings 58 and 60 processed in the punching process described above. More specifically, this is to secure a flat surface for pressing the base 52 when the burrings 58 and 60 are processed in the punching process described above.

Next, in step T600, the display unit 308 displays the determination result by the determination unit 306 on the screen 112 together with the product shape based on the three-dimensional data. In the present embodiment, since the distances L05 and L06 are equal to or larger than the reference value, the display unit 308 turns the judgment item column described as "burring to curved surface" in green in the judgment result table shown in FIG. Display in color. Further, the display unit 308 displays the number of NG points as “0” for the distance from the burring to the curved surface.

On the other hand, when the distance derived by the derivation unit 304 is less than the reference value, the display unit 308 displays the number of NG points in the determination result table and displays the NG points on the product shape based on the three-dimensional data.

Next, in step T700, the information acquisition unit 302 determines whether or not another second adjacent surface has been acquired. Specifically, the information acquisition unit 302 determines whether or not the second adjacent surface has been acquired in addition to the second adjacent surface that has already been determined. In the present embodiment, the second adjacent surface is not acquired in addition to the outer peripheral surfaces 58a and 60a, the end surface 50a, and the curved surface 56a. This completes a series of operations.

Here, the "line indicating the distance from the burring 58, 60 to the end face 50a" is a line connecting the burring 158, 160 to the end face 50a, and the length of the line is from the burring 158, 160 to the end face 50a. It is the same line as the distance of.
