Chamfer Parts

If the station for preparing the piece parts cannot handle part with chamfer, it is possible in the PLCM to automatically skip these piece parts (hereafter called chamfer parts). Piece parts which violates the restriction of the burning machine at this station are also treated in the same way.
The chamfer parts are marked with a special object code in PPANPARTS, so they will not be treated as piece parts in the assembly nesting. The chamfer parts have to be nested in the Nesting system.
The nesting of the chamfer part is not made with the original part geometry. The circumscribed rectangle, optionally modified with EXC_TYPE_3, is used instead. The reason for this is that the resulting plate must be rectangular in shape since it shall be welded together with the other piece parts.
When a chamfer nesting is stored a file is created with the following contents:
-
DNC ID
-
Burner ID
-
Paint TS
-
Paint OS
-
Length
-
Width
-
Thickness
-
Quality
The name of the file is <chamfer part>.chamfer.
When a assembly part includes chamfer parts, the raw plate information is taken from the file above. The DNC id and the burner id is stored in the burning sketch.
It is not possible to make the nesting of an assembly part containing chamfer parts, until all chamfer parts have been nested. The system checks if the file mentioned above exists.
If a chamfer nesting is deleted the chamfer file is deleted if the chamfer part has not been used in the assembly nesting. Otherwise the chamfer file is renamed to <chamfer part>.del and the assembly nesting is deleted as well.
There is also an option to PLCM to accept that plate parts have been burnt to shape already before being brought to the panel line. The panel line is then used for welding, marking and blasting only. It is controlled by the default parameter S1_MARK_INDPARTS _CHAMFER. If this is set to Yes and at least one individual part has characteristics as indicated above, then all the remaining individual parts belonging to the same assembly part are supposed to be treated in the same way.
