This setup covers the following Schelling saws.
Saw Transfer mode
Schelling Commander 4 9
- Make sure System parameters are set to create data for cutting dimensions
Saw Transfer parameters - Set up an entry for the saw(s) in the Saw transfer parameter list. The parameter values to set are as follows.
Transfer mode - set to: 9
Path for saw data - can be any directory you choose. This is the location of the NC files. The filename is runnumber.NC (e.g. 1000023.NC)
Make sure any saw parameter lists used have the Saw parameter: Saw model set to 51. This is a single saw.
Cutting dimensions - appear on printouts and pattern displays but the function codes shown are provided for visual checking only:- they cannot be manually entered at the saw controller. Function codes are:-
7 - Head cut
3 - Rip
6 - Crosscut
4 - Recut
5 - Multiple uneven recut
Cutting dimensions cannot be changed manually.
The cutting dimensions are stored in a .CUT file with 15 addresses per program and up to ten programs per pattern.
Label information in the NC file - The system also creates part-related label information in the NC file. Each part is given a section of lines as follows.
Line Size Schelling data Data

4 part number part list item number
1 MM (3) Inch (4) measurement mode (3=metric,4=inches)

T002, 003 and 005 display numeric values in 1/100 mm or inches.
Information boxes - Items with a * indicate that you need set an Information box in part list for that data to be available.
Crosscutting identical strips with recuts - Strips which have the same crosscuts but a different recut arrangement are crosscut separately.
Part sorting in patterns - When optimising for saw model 51 recut parts in strips are sorted to the right (as viewed on the screen). Recut parts are sorted to the left for all other saw models. The effect of the system parameter 'Largest cuts first' remains unchanged.
Part and material codes - there are restrictions on the length of part and material codes that can be used for this transfer. Make sure that the part and material codes used match the Schelling requirements.
********************
Schelling saw transfer - duplicate parts in strips with recuts - revision of strip set rules
This update resolves a reported problem when transferring to Schelling Commander 4 saws.
Where two strips have the same crosscuts (but produce different part item numbers at crosscut) and the strips contain recuts, it is the convention of the Schelling controller that the strips are crosscut in different sets. This update ensures that this convention is followed. In previous versions of the software, it was assumed that such strips were cut in the same set.
Note that duplicate part stacks are not supported by the Schelling format. Optimising parameter Duplicate parts - show in single pattern should be unchecked.
Summary of rules for crosscutting strip sets on Schelling Commander 4
Assuming that all dimensions in the strips are identical, two strips can be crosscut together in the same set if any of the following apply:
- The crosscuts produce the same part numbers and there are no recuts.
- The crosscuts produce the same part numbers. Recuts are present and produce the same part numbers.
- The crosscuts produce different part numbers and there are no recuts.
The different part numbers are represented by 'V' lines in the Schelling .NC file.
In this case the rips (Lxx) cannot be compressed. There must be one rip line for each strip in the set.
The strips must be crosscut in different sets if any of the following apply:
- Crosscuts produce different part numbers. Recuts are present and produce the same part numbers.
Reason: the controller cannot mix 'V' lines with recuts (Nxx)
- Crosscuts produce different part numbers. Recuts are present and produce different part numbers.
Reason: the controller cannot mix 'V' lines with recuts (Nxx)
- Crosscuts produce the same part numbers. Recuts are present but produce different part numbers. Reason: There is no 'V' line facility for recuts so each recut section must have its own crosscut section.
