The CAD progress management system described in Patent Document 1 processes a CAD drawing by uniformly dividing it into elements such as lines and surfaces. However, it is impossible to determine what shape it represents from elements such as lines and surfaces, and the figure image data such as side view and sectional view to be displayed cannot be expected to increase or decrease, and the numerical value itself can be obtained. Even so, it is difficult to assume the shape up to the final drawing, and the overall progress cannot be judged, which may be far from the actual.

Ask for. In addition, the calculation unit 308 multiplies the number of each unique shape (number of parts having each unique shape) possessed by the newly designed product by a weighting coefficient corresponding to the number of parameters assigned to the newly designed product. Find the grand total. Next, the calculation unit 308 calculates the degree of progress by dividing the grand total for the newly designed product by the grand total for the already designed product. Although the method for calculating the degree of progress from the number of unique shapes (features) and the number of parameters has been described here, the present invention is not limited to this, and any data that contributes to the progress of the features and the overall design work The degree of progress may be calculated from

  The transmission unit 309 transmits data indicating the degree of progress calculated by the calculation unit 308 to the management terminal 30.

  Next, with reference to the flowcharts shown in FIGS. 10 to 12, the progress degree calculation process executed by the progress degree calculating apparatus 10 according to the present embodiment will be described. In order to facilitate understanding, both the already designed product and the newly designed product are assumed to be a single component.

When the control unit 300 of the progress calculation device 10 receives an instruction from the management terminal 30 to transmit data indicating the progress of work for designing a new design product (new design target product that is a design target). The progress degree calculation process shown in FIG. 10 is started.
First, the control unit 300 acquires the specifications to be satisfied by the newly designed product from the CAD device 20 (step S100). For example, when the newly designed product is a lower case, data such as height, width, depth, and weight set in advance is acquired.

  Next, the control unit 300 refers to the already-designed product table 211 and the specification table 212 stored in the design database 210, and identifies the already-designed product having the most similar specifications (step S101). It should be noted that any known method can be employed as the similarity calculation method, and for example, a least square method or the like may be used. It is also possible to adopt a technique such as selecting one or a plurality of objects whose similarity is equal to or higher than a threshold value, presenting it to the user, and selecting an object that the user determines to be optimal.

  Next, the control unit 300 acquires data relating to the specified already-designed product from the shape / number table 213 and the parameter table 214 (step S102).

  Next, the control unit 300 acquires CAD drawing data under design from the CAD device 20 (step S103).

  Subsequently, the control unit 300 specifies a portion having a shape substantially the same as the shape specified by the image file 230 from the shapes specified by the acquired CAD drawing data, and determines the number of the specified portions. Count (step S200).

Details of this processing will be described with reference to FIG.
First, the control unit 300 identifies one path with reference to the image file table 215 (step S201). Next, an image file obtained by the specified path is acquired (step S202). For example, information “C: / xx / rib” obtained by combining the path indicating the rib shape and the image file name indicating the rib shape is acquired from the image file table 215 illustrated in FIG. 5, and the image existing in “C: / xx” is acquired. Get the file “rib”.

  Next, the shape represented by the CAD drawing data acquired in step S103 and the image represented by the acquired image file “rib” are added together and represented by the image file in the shape represented by the CAD drawing data. The number of shapes is counted (step S203) and recorded in the number recording table 222 (step S204).

Subsequently, it is determined whether or not the processing has been completed for all shapes (step S205).
When the unprocessed shape remains (step S205; No), the process returns to step S201, the unprocessed shape is specified with reference to the image file table 215, and the process is continued.

On the other hand, when it is determined in step S205 that the processing has been completed for all the shapes (step S205; Yes), the processing returns to the processing illustrated in FIG.
Subsequently, the degree of progress is calculated (step S300).
This calculation process will be described in detail with reference to FIG.

  First, the number of each shape is multiplied by a corresponding weighting coefficient from the already-designed product data acquired in step S102 (step S301). For example, when the data shown in FIG. 4A is recorded in the shape / number table 213, the rib shape is 16 × 0.8 = 12.8 according to the weighting coefficient table 221 shown in FIG. Regarding the shape, 4 × 1.5 = 6...

Next, the number of parameters assigned to the already designed product is acquired, and the weighting coefficient corresponding to this is multiplied (step S302).
Subsequently, the weighted numbers are summed (step S303). In other words, it corresponds to the number of unique shapes and the number of parameters assigned to the pre-designed product that the newly designed product (the product to be designed this time) has the closest specification to the pre-designed product (designed product). The total sum (total value) of the values multiplied by the weighting coefficient to be obtained is obtained.

That is, a value X expressed by the following equation is obtained.
X = Σ (ni · αi) + m · β
ni: number of i-th shape αi: weighting coefficient to multiply the number of i-th shape m: number of parameters assigned to the already designed product β: weighting coefficient to multiply the number of parameters i = 1 to N N: Number of specific shapes

  Next, the number of shapes recorded in the number recording table 222 in step S204 is multiplied by a corresponding weighting coefficient (step S304). For example, if the data shown in FIG. 7 is recorded in the number recording table 222, 4 × 0.8 = 3.2 for the rib shape and 2 for the boss shape according to the weighting coefficient table 221 shown in FIG. X1.5 = 3 ... is required.

  Next, the number of parameters assigned to the newly designed product is acquired from the CAD drawing data, and this is multiplied by a weighting coefficient (step S305).

  Subsequently, the weighted numbers are summed (step S306). That is, a total sum (total value) of values obtained by multiplying the number of unique shapes of the newly designed product and the number of parameters assigned to the newly designed product is obtained.

That is, a value Y expressed by the following equation is obtained.
Y = Σ (pi · αi) + q · β
pi: number of i-th shape αi: weighting coefficient for multiplying the number of i-th shape q: number of parameters assigned to the newly designed product β: weighting coefficient for multiplying the number of parameters i = 1 to N N: Number of specific shapes

Next, the degree of progress Y / X × 100 (%) is calculated by dividing the total value obtained in step S306 by the total value obtained in step S303 (step S307).
Subsequently, the control unit 300 notifies the management terminal 30 of the calculated progress (transmits data indicating the calculated progress to the management terminal 30) (step S308), and then returns to the processing illustrated in FIG. For example, the management terminal 30 notifies this as shown in FIG.

  As described above, according to the present embodiment, it is possible to calculate the progress of the design work in consideration of the progress of the work for setting parameters. The manager of the design work can determine the progress of the entire design work while assuming the form up to the final drawing.

(Embodiment 2)
In the first embodiment, the design target is a component, but the design target is applicable not only to a single component but also to an assembly in which individual components are combined.
Hereinafter, an example applied to an assembly will be described.
The configuration of the system according to the present embodiment is basically the same as the configuration shown in FIGS.

  However, when the already-designed product data is acquired in step S102, the already-designed product data of each part constituting the assembly is acquired.

  Also, when CAD drawing data is acquired in step S103, CAD drawing data relating to each part is acquired.

Subsequently, in step S203, when counting the number of already-designed product data for each characteristic shape, the number is counted for all parts.
In step S302, when determining the number of parameters for the already-designed product data, the number of parameters for all parts is determined.
In step S304, when the number is counted for each characteristic shape, the number is counted for the designed parts of all the parts.
In step S305, when the number of parameters is obtained, the number of parameters already designed for all parts is obtained.

Alternatively, the number of parts may be acquired as a parameter of the already designed product data, and the number of parts may be one of the parameters. Further, a design omission may be prevented by comparing the number of parts actually designed and the number of parts acquired as parameters.
Further, in addition to the number of specific shapes (features), which are constituent elements of the part, information on commercially available products in the part, information on presence / absence of interference between parts, and the like may be acquired together.

  As described above, according to the present embodiment, it is possible to calculate the progress of the design work for the assembly in consideration of the progress of the work for setting parameters. In addition, the manager of the design work can determine the progress of the entire design work while assuming the shape up to the final drawing of the assembly.

  In addition, this invention is not limited to said embodiment, Various deformation | transformation (a deletion of a component is included) and application are possible for said embodiment.

  In the above embodiment, specification data indicating similar specifications is specified in step S101, and already-designed product data is automatically acquired in step S102. For example, a plurality of specification data indicating similar specifications are specified, and The already-designed product data may be sent to the CAD device 20 or the management terminal 30 for display, and the user may select one of them. In this case, the already designed product data selected by the user is acquired in step S102.

In the second embodiment, the already-designed product data read from the database is used as it is. However, a combination of a plurality of design data or data obtained by removing a part of design data from one design data may be used. When the control unit 300 determines that the specification of the design target is more than one or more parts from the specification of the design target and the specification of the pre-designed product, the control unit 300 adds the missing parts to the data of the pre-designed product. Data of an already designed product having a specification corresponding to the above specification may be additionally acquired. Conversely, if the control unit 300 determines from the design target specifications and the specifications of the pre-designed product that the specification of the design target is less in one or more parts, Data excluding data of already designed products having specifications corresponding to the specifications of the parts may be acquired.
Further, when determining the degree of progress of the assembly, a plurality of parts 01 are obtained from the already designed product data of the assembly A1 for the part 01 constituting the assembly, and from the already designed product data of the assembly A2 for the part 02. Assembly parts may be used.

In the above embodiment, the CAD drawing 400 and the image file 230 are compared to determine the shape (feature) on the CAD drawing. The present invention is not limited to this.
For example, by analyzing CAD drawing data, a protrusion shape having a circumference of a predetermined ratio or more is a shape (feature) of a boss, and a thin plate shape whose width to height ratio is within a predetermined range. You may make it discriminate | determine a protrusion in the shape (feature) of a rib.

An accompanying shape (accompanying shape) may be added to the basic characteristic shape.
For example, the boss (boss-shaped portion) shown in FIG. 14A may be detected when chamfering, taper processing, R processing, etc. are performed as shown in FIG. 14B. .
In this case, for example, referring to the shape number adjustment table 223 shown in FIG. 15, when counting the number of bosses, one is used for chamfering, taper processing, and R processing for the boss only. When one is applied, 1.3 pieces are applied, and when any two of chamfering, taper machining and R machining are applied to the boss, 1.6 chamfering, taper machining and R machining are applied to the boss. In this case, the number of shapes may be adjusted according to the content of the accompanying shape, such as 1.9 (in this case, when the shape portion is processed, the number of shapes is Increasing the size compared to when no processing is performed means that when the shape part is processed, the number of shapes is multiplied by a larger weighting coefficient than when no processing is performed. Substantially the same).
Further, the weighting coefficient may be changed according to the accompanying shape with reference to the weighting coefficient table 221 shown in FIG. 16 (the number of shapes is counted as 1 at this time). In any case, by adding an accompanying shape, the number or coefficient is adjusted so that an increase in the burden on the designer can be reflected.

In the above embodiment, the weighted addition of the number of predetermined shape parts (features) and the number of parameters of the newly designed product, and the number of the predetermined shape parts of the already designed product, Although the quotient of the weighted addition of the number of parameters is used as an index indicating the degree of progress, the present invention is not limited to this. For example, the quotient between the number of predetermined shape parts of the newly designed product and the number of predetermined shape parts of the already designed product may be used as an index indicating the degree of progress. Similarly, the quotient of the number of predetermined parameters for a newly designed product and the number of predetermined parameters for an already designed product may be used as an index indicating the degree of progress. Further, the quotient of the number of the predetermined shape parts of the newly designed product and the number of the predetermined shape parts of the already designed product, and the predetermined parameter of the newly designed product designed The weighted average of the quotient of the number and the number of predetermined parameters of the pre-designed product may be used as an index indicating the degree of progress. Furthermore, elements other than the number of parts having a predetermined shape and the number of parameters may be used as a basis for calculating the degree of progress. For example, for a newly designed product, the value obtained by weighting and adding the number of parts with a specific shape designed, the number of parameters designed, and the number of designed drawing elements (points, splines, etc.) The ratio of the number of parts having a specific shape of the product, the number of designed parameters, and the value obtained by weighted addition of the number of designed drawing elements may be used as an indicator of progress.
Furthermore, a value obtained by weighted averaging the index indicating the degree of progress obtained in the above embodiment and the index indicating the degree of progress used in another known method may be used as the final index indicating the degree of progress.
