Basic parameters tab

Edges and distances

Minimum distance between parts

The minimum distance between the parts is entered here.

Common cut

The exact distance to one another is entered here for parts that are suitable for common separation cuts. This value is read from the technology table of the selected machine and should not be changed here.

Grid

The distance of the grid points is entered here. The grid points serve as snap points at which the parts for nesting can be placed. The finer the grid, the more precise the nesting and the longer the nesting time. It is sufficient to set the value to half the distance between the parts.

Global nesting limits

The value in the X direction is entered here for a vertical nesting limit.

Exact part spacing

With this option, the defined minimum distance between the parts is maintained as the exact distance. This can increase the nesting time.

Part sorting before nesting

Part sorting

Here, you select how the parts are sorted before nesting. This sorting determines the sequence in which the parts (in full quantities) are nested one after another. The selection can be made via the drop-down list or the dialogue box, which opens via the .. button. See also: Parts sorting dialogue box

Type of subgroups

Here, you select whether the parts are to be additionally grouped. The following options are available:

  • Sort group 0 : No grouping.
  • Sort group 1 : They are grouped by deadline and sorted within the group.
  • Sort group 2 : They are grouped by quantity and sorted within the group.

The selection can be made via the drop-down list or the dialogue box, which opens via the .. button. See also: Parts sorting dialogue box

Subgroup size

Subgroups are generated here according to deadline or quantity:

  • For grouping by deadline: The orders are grouped according to the number of days per group up to the deadline. Within this group, sorting takes place according to the type set in Part sorting.
  • For grouping by quantity: The orders are grouped according to the number of pieces per group. All parts whose number of pieces is higher than the entered number of pieces are sorted upwards. The parts whose quantity is smaller than the entered quantity are sorted according to the type set in Part sorting.

Sorting by nesting

Part sorting

Here, you select the pattern according to which the sheet is to be processed. The selection can be made via the drop-down list or the dialogue box, which opens via the .. button. See also: Sorting parameters dialogue box

Sorting width

The width for the rows of the pattern is entered here.

Sort multi-torches

With this option, the torch stages for production are taken into account. The parts are manufactured within a row according to the ascending torch stage. This means: One after the other for all parts of torch stage 1, then all parts of torch stage 2 and finally all parts of torch stage 3.

Sheet sorting

Here, you select how the sheets are sorted according to nesting. The sorting serves as a sequence for production. The selection can be made via the drop-down list or the dialogue box, which opens via the .. button. See also: Sheet sorting parameters dialogue box

Nesting parameters

Nesting strategy

Here, you select the nesting strategy to be used. Depending on the strategy, the nesting types pixel nesting, power nesting and place nesting are combined in different ways. The selection can be made via the drop-down list or the dialogue box, which opens via the .. button. See also: Nesting strategy dialogue box

Powernesting level

Here, you select the level for power nesting. The higher the level, the more combinations are tested during power nesting. This may lead to a better result, but at the same time it also increases the calculation time of the nesting.

Nesting corner

Here, you select in which corner the nesting should start. If corners are combined with one another, all specified corners are nested and the best result is adopted. The selection can be made via the drop-down list or the dialogue box, which opens via the .. button. See also: Nest corner dialogue box

Storage corner

Here, you select the corner into which the nesting result is moved after nesting. The selection can be made via the drop-down list or the dialogue box, which opens via the .. button. See also: Storage corner dialogue box

Nesting direction

Here, you select in which direction(s) the parts are nested, starting from the nesting corner. The selection can be made via the drop-down list or the dialogue box, which opens via the .. button. See also: Nesting direction dialogue box

Part parameters

Check geometry and NC machining

With this option, the distance between parts is taken into account for NC elements (lead-in paths or tool geometries) when nesting.

Check station allocation

With this option, the parts for each sheet are selected so that the existing tool stations are sufficient and do not have to be refitted. The utilisation of the sheet can therefore be somewhat lower. The option is only for punching and combination machines.

Part rotation also during disposal

This option also rotates parts that are disposed of (flap, stop or lift) for a better nesting result. Since the position of the disposal changes as a result, it must be corrected after nesting. See also functions Laser disposal and Punching disposal.

Common cut between different parts

With this option, a common separation cut is also permitted between different parts if these are suitable for this purpose.

Suppress certain colours

This option suppresses nesting elements to which the selected colours are assigned. This should be applied to elements that do not represent a subcontour. Accordingly, these are, for example, bend lines, engravings or all inner contours into which nothing more should be nested. The colours are selected via the dialogue box, which opens via the .. button. See also: Colours to be suppressed dialogue box

Nesting for multi-torches

This option activates nesting for multi-torches.

Sheet parameters

Determine optimal sheet

This option nests to all specified sheet formats and applies the formats that allow the highest utilisation. The nesting result can be a mixture of different sheet formats.

Determine only one format

With this option, you can nest to all specified sheet formats and select a format from the respective results, which will then be used for the entire nesting. If the number of available sheets of the format is not sufficient, a mix of the formats is allowed.

Rotate sheets 90 degrees

This option rotates all specified standard nesting sheets by 90 degrees.

Prefer remnant sheets

With this option, all remaining sheets are used for nesting first, even if this results in more waste. Only then are new sheets used.

Maximum number of articles per sheet

The maximum number of different parts that can be nested on a sheet is entered here. The indication "0" means that the number is unlimited.

Multiple runs

Number of runs

The maximum number of times a nesting sheet can be produced is entered here. The nesting then contains as few different sheets as possible, which may, however, be produced several times up to the specified value. This may reduce the utilisation of the sheets.

Minimum utilisation capacity in %

Here, you enter the minimum percentage utilisation required for a sheet to be produced several times.

Global divider

Here, you enter the minimum number of times each sheet is to be produced. The quantities of the parts are rounded up according to the global divider and fewer different sheets are produced. In this case, the maximum number of pieces allowed for a part can be exceeded.

Buttons

Set default nesting parameters

The respective default value is reset for all parameters.
