System parameter to set how the program works for dividing a part list and creating a cutting list and board list
On optimising the program takes the part list and creates a cutting list and a board list by selecting relevant boards from the board library.
This parameter controls this process.
The options are:-
Use one board list per run
Use one board list per batch
Allow re-use of offcuts from earlier runs in a batch
Select the option via the radio buttons
The last option is set with a check box and is only available when using one board list per batch
Use one board list per run
This is the most common way of working. A separate board list is created for each cutting list and they are optimised separately.
Use one board list per batch
Where there is a batch of part lists to optimise an alternative is to create a single board list and optimise all the lists with a common board list.
The board list name is based on the name of the batch rather than the cutting list. This allows all cutting lists to share the same board list so each run can be optimised with same board list. The program operates to prevent offcuts being used twice and to ensure that Board quantities are controlled across runs.
The global board list name is always set when optimising in this way. New batches have the global board list name set from the batch name. Existing batches have the global set from the board list name from the first line of the batch. The global board list name can be changed but it cannot be deleted.
If the batch is saved via 'Save As' the global board list name is set to the new batch name.
Allow re-use of offcuts from earlier runs in a batch
This option determines how the offcuts are used when optimising a batch from a common list. Check the box to allow the offcuts produced in each run to be available for the next run.
This method can be useful, for example, for examining the effect of several weeks production in one batch without affecting the stock in the board library.
The optimiser achieves this by calculating the offcuts produced by each run and appending these to the batch board list so they are available for the following runs. The appended offcuts are separated from the stock boards by a marker board with zero dimensions. It is important not to delete or modify this marker since the program relies on its presence in order to function correctly.
- When this option is used with the Stock Control stock is automatically reserved for the batch after optimisation. If the run is later changed by, for example, deleting a pattern, changing the run quantity, or adding new patterns this stock reservation is adjusted but this may result in there not being enough stock of some boards.
Notes
- The common (or batch) board list can accommodate 5000 boards and offcuts.
- When re-using offcuts take care not to edit or alter the intermediate runs for cutting as this would alter the offcuts available for each run.
