Optimising parameter to set how duplicate parts are shown in patterns
A duplicate part is a part which has the same dimensions as other parts but is labelled differently (a left and right hand door or panel is a common example. The options are:-
Show in single pattern
Show in duplicate patterns
Show in single pattern
Where the parts are shown in a single pattern (see above) this can improve the number of cycles and yield. The asterisk against a part label shows the stack (6 boards) consists of a mixture of differently labelled parts. In this example DOOR/L and DOOR/R.
Show in duplicate patterns
This is a useful option where the cutting is '1 high' (since there is no stacking) or where there is some other production requirement to keep the parts separate, for example, there are differences in a later production process.
Notes
- Combine Duplicates - Some duplicate parts arise by accident, from a typing error, or from creating one list from two similar lists. In this case it may be preferable to remove the duplicate part in the part list before optimising.
- The definition of a duplicate part is set by the Optimising parameter: Part list fields for defining duplicates (optimising)
Grain matching
Some types of grain matched master (parent) parts can be treated as duplicates when cut at a saw.
Create master part - divide at saw - master parts of this type can be considered as duplicate parts. This allows master parts of the same size (but with similar or different sized components) to be combined with each other and standard parts. The existing duplicates criteria must also apply for parts to be considered as duplicates.
Cut parts in main pattern - in this case the parts are divided during the main cutting operation so for these to be duplicates the contents of each grain match 'area' or master part must be identical and have the same underlying template as they are operated on identically. These sets of parts are not combined with standard parts of the same size as they require different subsequent recuts etc.
