To configure the offset, the Performed Machined Contour option must be marked as All or Only Marked, in addition, the Performed Machined Contour option must be marked in the part register.
1. Access CNC/CNC Configuration:
After selecting CNC Configuration, the system will display the following screen to select the information for Performed Machined Contour, when doing so, the fields for selecting Offset will be displayed.
Next, it will be necessary to configure the Machined Contour information in the part registration so that the Builder processes the contour correctly.
Calculation of parts offsets
Next, it will be shown how the Builder handles the offset and edge band discount settings of parts in Machining centers and Nesting machines.
Below is the information on each offset and where to find them:
Edge band offset
This offset value can be registered on the band inserted in the part. It can be zero or contain the value that you want to add to the part for each band inserted in it (usually the edge band thickness is used).
This offset value is registered in the part to be added to its value in X and Y at the time of cutting.
It is mainly used for contours machined in CNC centers, to eliminate imperfections in the parts coming from the Beam Saw Machine.
In the case of Nesting machines, this offset is commonly used in composed panel, where the part must be machined after gluing the parts to eliminate imperfections at the ends.
When configuring the plug-in setups, we can evaluate how offsets will be handled.
Example of a part with multiple plugin configurations:
Band thickness (on 4 sides): 2mm
Band offset: 2mm
Offset X : 10mm
Offset Y: 5mm
Finished piece measurement: 1000x500x18.5 (finished piece with holes, edge, etc...)
Measure of the Part after being cut in the Beam Saw Machine: 1010x505x18 (in this case, the thickness of the applied edges is always discounted, and the offsets related to the edge and the part are added)
Option 1 - Add marked edge band and plate offset (1010x505)
We can see in the image below that the part will leave the processes with the final values added to the plate offset, discounting the edge band thickness and adding the offset relative to the edge band.
In the image below, we can see the piece in its final measurement:
Option 2 - Add only plate offset
In the image below, we simulate how much is removed from the contour of the part by the cutter. In the case of this option, we eliminate the thickness of the edge band and do not add the offset relative to the edge band.
In this image, we have the final measurement of the piece after the contour has been made.
Option 3 - No add offset option checked
In this option, neither the offset relative to the edge band nor that of the plate is added to the part, so, in the image below, we see the milling cutter eliminating from the part the value of the offset of the plate and the thickness of the edge band.
Final measurement of the piece will be 996mm X 496mm
Option 4 - Only the option to add edge band offset is checked
In the image below, we see the cutter eliminating from the part on the contour only the offset of the plate.
And the part in its final measure, after the contour has been machined.
