DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a design management apparatus for managing the progress of various design tasks.

[0002]

2. Description of the Related Art As a well-known design method, there is a paper drawing using a drafting board. In this case, since the progress of the design work is displayed on the paper, the business progress management is performed. Was performed very easily by the visual inspection of the administrator.

In recent years, the design has been shifted to an automatic design system (hereinafter referred to as CAD) using a computer, and the drawing information is also stored in the design data inside the computer.
(In other words, CAD data). Such CAD data is invisible data unlike the design data in the conventional paper drafting, and thus it is becoming impossible for the manager to check the progress of the design work every day. Under such circumstances, it has become an urgent task in CAD design to be able to easily confirm the progress of daily design work, but no appropriate technology has been developed yet.

Japanese Patent Laid-Open Publication No. Hei 3-180971 discloses that a design object is classified according to its attributes and characteristics, a classification name is set, and a classification name is determined based on a target achievement level and an important visibility for a target value of a target index. Calculating the evaluation value in consideration of the above, it is disclosed that the design result between the different target indicators can be directly evaluated, but this technology,
It does not check the progress of the design work as described above every day.

[0005]

In the case of CAD design, there is some kind of data between the number of CAD data elements (that is, the number of text elements such as line elements or dimensions necessary for the design) and design milestones. There is a fact that the number of elements at the start of the design work and the number of elements at the time of the completion of the design work are almost constant, especially when considering the conditions. From this, it is possible to predict the number of elements at the time of starting and at the time of completion, and by using this, it is possible to set a model case of variation in the number of elements. In setting the model case, it is assumed that the assembly drawing is completed at the time of casting drawing release and that the number of elements increases linearly during the design period.

By comparing the model case with the daily variation of the data amount (in other words, the number of elements) in the actual design work, the present invention is focused on the point that the progress of the design work can be easily evaluated. It was done.

The present invention has been made in view of the above points, and has as its object to enable easy and reliable management of the progress of design work.

There is an excellent effect that the management of business progress in CAD design, which was difficult to manage conventionally, can be performed very easily.

[0013]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

The design management apparatus according to the present embodiment is intended for a case where a press die is designed using a CAD system.

In the case of designing a press die, a standard drawing A (see FIG. 3) required for designing a common part is prepared in advance,
The design work is to be performed in a procedure of drawing the product shape part B which is a dedicated part in the standard drawing A by CAD (see FIG. 4). Therefore, in the case of the present embodiment, the total data amount in the press die design work is the data amount necessary for drawing the product shape part B (in the case of the present embodiment, the line element fluctuation amount and the text element fluctuation amount) (FIG. 5).

As shown in the claim correspondence diagram of FIG. 1, the design management apparatus according to the present embodiment is required to complete a predetermined design operation (press die design operation in this embodiment). From the total data amount of the specific elements selected from the various elements (line elements and text elements in the case of the present embodiment) and the design period required to complete the design work, the standard data amount increasing as a standard ( In other words, the calculating means 1 for calculating the model case X), the data amount accumulating means 2 for accumulating the daily completed data amount, and the data amount accumulating means 2
And a display control unit 3 that outputs a command to display by comparing the completed data amount obtained by the above with the model case X calculated by the calculating unit 1. Specifically, FIG. As shown in FIG.
A database 12 for counting CAD data by the D device 11, a time-division processing system 13 for temporarily storing the amount of data transferred from the database 12, and a computer 14 for receiving data from the time-division processing system 13. And a personal computer 15 for displaying information from the computer 14 (in other words, data amount fluctuations).

In the case of this embodiment, the arithmetic means 1, the data amount accumulating means 2, and the display control means 3 are built in as the program contents of the database 12.

Next, the operation of the design management apparatus according to the present embodiment will be described with reference to a time chart shown in FIG. 5 and a flowchart shown in FIG.

First, CAD used for design management
Selection of the data is performed in step S _1. The selection is performed by input to the CAD device 11,
In the case of this embodiment, line elements and text elements (dimensions and the like) required for press die design are selected. In this case, the CA included in the standard diagram A among the line elements and the text elements is used.
Since the amount of D data is input in advance, the amount of data required from the start of the design work to the end of the design work is the line element change amount and the text element change amount. These data amount of definition is performed in step S _2, the standard increase in the data amount by calculation means 1 in step S ₃ (i.e., the model case X, Y)
Is calculated.

After that, the data amount accumulating means 2
The daily data amount is accumulated and collected by the AD operation or the dimension input (step S ₄ ), and the model case X, Y and the daily accumulated data amount X ′, Y ′ (see FIG. 5) are commanded by the display control means 3. ) Are displayed on the screen of the personal computer 15 so that they can be compared.
(Step S _5). Therefore, by comparing the model cases X and Y with the daily accumulated data amounts X 'and Y', it is possible to easily and surely manage the progress of the design work for comparison.

In the above description, the press mold design work is taken as an example, but it goes without saying that the present invention can be applied to other design work in general.

The types of data collected for design management are not limited to the line elements and text elements in the above embodiment, but may be various as long as the progress of the design work can be grasped. Can be selected. For example, the length of a line, the number of faces, the area of a face, the number of patches, the patch area, the number of constituent points, the number of GROUPs, and the number of jobs
The number, bounded area, number of paths, path length, number of base planes, CPU time, number of commands used, computer use time, and the like can be used.
