Tools planning method

The purpose of tools planning is to estimate the tools that are needed for production orders, service orders, and work orders. If a production order is planned, the required tools are determined using the routing that is linked to the item.

After the tools are planned, the Estimated Tool Requirements (titrp0111m000) session checks the availability of the planned tools.

The tools planning procedure is used in the following sessions:

  • Plan Tools Globally (titrp0211m000) session. The method is only used if the tool serial number is not specified.
  • Replan Tools (titrp1202m000) session.
  • Availability Check for Tools (titrp0213m000) session. This method is only used if the tool serial number is not specified.

The tools planning method takes into account the Tools Usage field in the Tool Numbers (titrp0102m000) session. The number of tools to be planned is determined by the Maximum Number of Tools to be planned. When LN plans tools with the Plan Tools Globally (titrp0211m000) session and with the Replan Tools (titrp1202m000) session, LN considers the alternative tool types. LN also takes into account the Planning Method field in the Tools (titrp0101m000) session. Depending on the value of this field, LN uses the following methods when planning:

  • Least Remaining Tool Life. LN first considers tools with the least remaining life.
  • Maximum Remaining Tool Life. LN selects tools with the maximum remaining tool life.
  • Based on Order Quantity. For the planning, LN selects tools with a remaining tool life equal to or greater than the requirement considered for the planning.
  • Not Applicable. The planning method is not applicable, which means the tool life is not applicable.

The tools planning method procedure considers all the previously-mentioned input and plans the tools. If the requirement cannot be satisfied in one check-availability procedure, a purchase quantity is recommended. If LN fails to plan the tools for the requirement, the requirement is not changed.
