Automatic cut-offs sorting needs minimum width and length specification. These parameters set minimum size of useful cut-offs. Sheet fragments which sizes are more or equal to set value will be saved in cut-off database after cutout for further use. All cut-offs which sizes are less than set values will be considered as waste and they will be marked on cutting charts.

After cutout completion useful parts and cut-offs will be created. Parts will be delivered to further processing and cut-off packing lists will be generated for delivery to stock.

Cut-offs effective use in further cutouts is specified by check boxes setup.

First of all the system checks cut-offs convenience for use in cutout. If cut-offs can be used in cutout, they will be cut first and then the whole boards will be cut. If the user selects only boards cutting, cut-offs will not be cut at all, i.e. the system does not use cut-offs database.

If cut-offs and boards are cut together, two kinds of cut-offs cutting control will be executed:

  • by material using ratio (MUR) minimum value;
  • by cut-offs cutout rationality.

In first case MUR minimum value is set for cut-offs cutting. If panels are placed on a cut-off and MUR value is less than set value, such cut-off will not be cut and it will stay in cut-off database.

Second control variant can be used in case if new cut-offs total area is more than total area of usable cut-offs. It will lead to material total amount in cut-off database increase. In other words in spite of effective material saving due to maximal cut-offs use, it may lead to extra costs from organizational point of view.

For cut-offs use optimization and parts database loading there is a check box that allows to arrange the panels from additional list on cut-offs without panels from main list placing. Cut-offs that are not used for panels from main list arrangement will not be used for panels from additional list cutting.
