Define combining optimizations for requisitions

You can define company-level settings for multing and plate nesting for new requisitions. If necessary, the combining optimizations can be adjusted for each individual requisition.

  1. At the bottom of the Requisition Company Standards dialog box, click Combining Optimizations.
  2. To use material grade substitutions with the optimization settings when performing a combining run, on the General Settings tab of the Combining Setup dialog box, select the Use Grade Substitutions check box.

    Grade substitutions must be set in the Shape / Grade / Size Maintenance dialog box. If the grade substitutions are not set, the material grades in the combining run and in the supplier pricing data set or the inventory need to match each other exactly.

  3. If you only want to mult and nest materials that are in the same sequence, select the Combine Only Within Sequence check box.

    Selecting the Combine Only Within Sequence check box might be useful in medium or big jobs, but we do not recommend selecting it for small jobs.

  4. Click the arrow buttons to move the optimization options that you want to use to the Optimizations Included list.
    The options are:
    • Inventory Exact-Match (In Stock): Use this option for inventory items in stock that are an exact match without the use of kerf or clamp allowance.

    • Inventory Exact-Match (On Order): Use this option for inventory items that are on purchase orders and have not yet been received and that are an exact match without the use of kerf or clamp allowance.

    • Inventory Least-Scrap (On Order): Use this option for inventory items that are on purchase orders and have not yet been received and that will provide the least amount of scrap.

    • Inventory Least-Scrap (In Stock): Use this option for inventory items in stock that will provide the least amount of scrap.

    • Warehouse Least-Scrap: Use this option to give preference to warehouse items that will provide the least amount of scrap. Warehouse items will only be used when they provide less scrap than the available inventory items.

    • Warehouse Force Inventory: Use this option to force the use of inventory regardless of the amount of scrap, no matter where it is located in the Optimizations Included list. This option is the opposite of Warehouse Least-Scrap.

      Note that you can only include Warehouse Least-Scrap or Warehouse Force Inventory, not both.

  5. Use the Move Up and Move Down buttons to modify the order of the optimizations.

    The order is important while performing a combining run.

  6. Click the Mult Settings - Linear Material tab to open it.
  7. In Multing Software, select the multing software that you are using.
  8. If you want to apply the material kerf settings defined in Shape / Grade / Size Maintenance to the combining as part of the cutting pattern, select the Apply Kerf check box.
  9. Open the Plate Nesting Settings tab.
  10. In the Plate Nesting Software list, click the plate nesting software that you are using to select it.
  11. In the Shear Cut Optimization list, click a suitable shear cut option to select it.
    The selected option determines the plate allowance to be used with the combining:
    • Use None when cutting plate on a burn table.
    • Use Shear Cut - First Cut Along Length or Shear Cut - First Cut Along Width to alert Tekla EPM that the nesting needs to allow for that type of cut first. Then, the nesting will allow for all subsequent cuts to be made with that condition.
  12. If the material grain direction is unimportant and you want Tekla EPM to create the best possible optimization of a plate, select the Rotate Plates for Best Fit check box.
  13. If necessary, select the Apply Kerf check box.

    See step 8.

  14. Click Save.
  15. Remember to click Save in the Requisition Company Standards dialog box to update the combining optimizations.

When the settings are saved, the Requisition Company Standards dialog box closes.
