In the technology described in this document, the shape of the sheet metal product is recognized based on the preset cross-sectional shape data based on the drawing information of the sheet metal product to be estimated, and then the machining process is selected based on the recognized cross-sectional shape of the sheet metal product. To do. Then, the cost required for the estimation along with the machining process is calculated.

Also, a cost estimation system that can be simply estimated when changing the design of a mold in order to create a detailed estimate of parts cost and mold cost has been studied (for example, see Patent Document 2). ). The technique described in this document includes cost information storage means for storing cost information for associating a part material and its cost with a part processing step and its cost. Then, the material of the part to be processed and a plurality of processing steps are specified, and the cost related to the specified material and the cost related to each processing step are acquired from the cost information. And the cost of components is estimated based on each acquired cost. Furthermore, in this system, it is possible to estimate the cost by utilizing information estimated by others, and the component manufacturer objectively recognizes its position with respect to the cost for manufacturing the component, and makes an effort target. Can be set.

Specifically, the target value calculation means 212 of the control unit 21 uses the standard cost data storage unit 24 to specify the unit price corresponding to the material identifier recorded in the basic process data storage unit 23. Then, the target value calculation means 212 calculates the standard material cost by multiplying the specified unit price by the usage amount for each material used in the manufacture of this part.

  Further, the target value calculation means 212 uses the standard cost data storage unit 24 to specify the unit price corresponding to the process identifier recorded in the basic process data storage unit 23. Then, the target value calculation means 212 calculates the standard process cost by multiplying this unit price by the required time.

  Then, the target value calculation means 212 calculates a standard cost that is the sum of the standard material cost and the standard process cost, and records this standard cost as a target value in the estimated data storage unit 27 in association with the component identifier.

  Next, the control unit 21 of the estimate support server 20 transmits a processing review request (step S1-4). Specifically, the process review request unit 213 of the control unit 21 transmits a process review request to the supplier terminal 30. This processing examination request includes data related to the part identifier to be examined.

  In this case, the supplier terminal 30 executes a detailed information request process (step S2-1).

Calculate the estimated amount.

  Specifically, the estimate calculation means 216 specifies the unit price corresponding to the material identifier recorded in the editing process data storage unit 26 in the supplier cost data storage unit 25. And about each material used in manufacture of this component, a supplier material cost is calculated by multiplying the specified unit price by the usage amount.

  Further, the target value calculation unit 212 specifies a unit price corresponding to the process identifier recorded in the editing process data storage unit 26 in the supplier cost data storage unit 25. Then, the unit cost is calculated by multiplying the unit price by the required time.

  Next, the estimate calculation means 216 calculates a supplier cost obtained by adding the supplier material cost and the supplier process cost, and estimates the supplier cost in association with the part identifier and the supplier identifier. Record in the data storage unit 27. Further, the estimate calculation means 216 generates a confirmation web page including data relating to the calculated estimated amount, and transmits it to the supplier terminal 30.

  In this case, the supplier terminal 30 executes an estimate confirmation process (step S2-3). Specifically, an estimated amount confirmation screen is output to the browser of the supplier terminal 30 that has received this web page. Using this screen, the person in charge of the supplier confirms the estimated amount.

  Next, the supplier terminal 30 executes a registration instruction process (step S2-4). Specifically, when the person in charge who has confirmed the estimated amount selects a registration instruction button on the browser, the supplier terminal 30 transmits a registration instruction to the estimation support server 20.

  And the control part 21 of the estimation assistance server 20 performs a registration process (step S1-9). Specifically, the estimate calculation unit 216 records data relating to the calculated estimated amount in the estimate data storage unit 27 in association with the component identifier and the supplier identifier.

  In this way, the requesting company uses the estimated amount registered in the estimated data storage unit 27 to specify the ordering party for this part. In this case, a specific request for parts manufacturing can be made by registering the estimated amounts of a plurality of suppliers.
