  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a conceptual diagram showing an example of the configuration and connection destination of a specification information management system to which the specification information management method of the present invention is applied.

  That is, the specification information management system 10 to which the specification information management method of the present invention is applied is connected to the processing step 16 included in the specification information management terminal 14 and the production line 15 via the communication network 13. Is connected to a specification information confirmation terminal 17. The specification information management system 10 includes a specification information database 11 and a calculation unit 12.

The specification information management terminal 14 and the specification information confirmation terminal 17 are provided with input means such as a mouse and a keyboard (not shown). Further, in FIG. 1, only one singular specification information management terminal 14 is shown, and only one singular specification information management terminal 17 is shown for each processing step 16. May be.

  2 and 3 show examples of specification information lists, respectively. The specification information list 20 is a table that lists specification information including process conditions 21 and instruction values 22 set for the process conditions 21. In addition, when the process condition and the instruction value are changed, the specification information list 20 is assigned with a version number 23 as change history information and managed together with the change contents. For example, the specification information list 20 shown in FIG. 3 is a change from the specification information list 20 shown in FIG. 2 and 3 are assigned version 1 and version 2, respectively.

  Note that the contents of the process condition 21 and the instruction value 22 are not limited to the contents of FIG. 2 or 3, and may be any contents. In addition, any change contents are given a version number and managed as change history information.

  FIG. 4 shows an example of the configuration of the specification information list in each processing step. When manufacturing a product, the required specifications differ depending on the product, and the process conditions 21 and the indicated value 22 need to be changed accordingly. Therefore, the specification information list 20 is required for each different specification. In this embodiment, a unit in which the same specification unit is classified as a product type and a specification information list 20 exists for each product type is considered. Each type exists for each processing step 16, and a specification information list 20 exists for each processing step 16 even for the same type. The specification information list is assigned a version number 23 and is managed as change history information.

  FIG. 5 is a diagram schematically showing an example of the version of the specification information list used for each production schedule. FIG. 5 shows the production schedule of product type C in processing step a. In order of time, version 1 specification information list is used in production schedule L1, and version 2 specification information list is used in production schedule L2. In the production schedule L3, an example in which a version 1 specification information list is used is shown.

  Next, the operation of the specification information management system to which the specification information management method of the present invention configured as described above is applied will be described using a flowchart.

  First, in the specification information management system to which the specification information management method of the present invention is applied, the operation relating to the setting for associating the production schedule with the version number of the specification information list used for this production schedule will be described with reference to the flowchart shown in FIG. I will explain.

  First, a production schedule to be newly set is selected (S1). Next, it is determined whether there are multiple versions in the specification information list that can be used for the selected production schedule (S2), and if it exists (Yes in S2), it can be used for the selected production schedule. From the plurality of versions of the specification information list, what is actually used for the selected production schedule is designated, and a setting process (S3) for associating the selected production schedule with the designated version number is performed.

  For example, as shown in FIG. 4, there are a plurality of versions of version 1 and version 2 in the specification information list that can be used for the production schedule of the product type C in the processing step a. Therefore, when the production schedule of the product type C in the processing step a is selected, either version 1 or version 2 is designated as the specification information list actually used for the production schedule, and the designated production schedule is designated. A setting process for associating with either version 1 or version 2 is performed.

  On the other hand, if there are no multiple versions in the specification information list that can be used for the selected production schedule (No in S2), the only version of the specification information list that can be used for the selected production schedule is selected. A setting process for associating the selected production schedule with the number of the only version, which is actually used for the schedule, is performed.

  For example, as shown in FIG. 4, only one version, version 1, exists in the specification information list that can be used for the production schedule of the product type B in the processing step a. Therefore, when the production schedule for the product type B in the processing step a is selected, a setting process for associating the selected production schedule with version 1 is performed.

  It should be noted that the latest version may be designated as the initial value when the production schedule is selected (S1). By doing so, it is also possible to realize an operation in which the selected production schedule and the latest version are normally associated with each other, and when a version is designated, another version is associated.

  Finally, when setting a plurality of production schedules, the processes of S1 to S3 are repeated (S4).

  For example, as shown in FIG. 5, if the production schedule of the product C in the processing step a is to be set to version 1 in the production schedule L1, version 2 in the production schedule L2, and version 1 in the production schedule L3, the production schedules L1 to L3 are set. On the other hand, the processes of S1 to S3 are repeated.

  With the above processing, in the specification information management system to which the specification information management method of the present invention is applied, it is possible to perform a setting for associating the production schedule with the version number of the specification information list used for this production schedule. Also, this setting can be changed any number of times.

  Next, in the specification information management system to which the specification information management method of the present invention is applied, the reference operation of the specification information list when producing according to the production schedule in the machining process will be described with reference to the flowchart shown in FIG.

  When producing according to the production schedule in the processing step, it is determined whether or not there is a version number that is set to be associated with the production schedule (S1). When the setting has been made (Yes in S1), a process of displaying a specification information list to which this version number is attached is performed (S2).

  The operator can instruct each of the specification information in the displayed specification information list to the machining process.

  The best mode for carrying out the present invention has been described above with reference to the accompanying drawings, but the present invention is not limited to such a configuration. Within the scope of the invented technical idea of the scope of claims, a person skilled in the art can conceive of various changes and modifications.
