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).
Plate Offset
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.
Plug-ins Configuration
When configuring the plugin setups, you can see how the offset will be handled for each of the options:
Examples of the part to be used:
- Thickness of edge tape (only on two sides of the part (top and bottom)): 1mm
- Offset of the edge band: 1mm
- Edge band X: 10mm
- Edge band Y: 10mm
Measurement of the piece already produced: 1000x500x18.5
Measurement of the piece after being cut on the Beam Saw Machine: 1010x510x18.5
Option 1 - All options checked (Add plate offset, edge band and discount edge thickness)
Image above with zoom applied:
Final shape : 1010x510
Contour: 1010x510
Note that the piece and the outline are exactly the same size, because the following calculation was made:
Final part: 1010mm by 510mm
Width: 1000mm + 10mm = 1010mm (part width + offset)
Height: 500mm + 10mm + 1mm + 1mm - 1mm - 1mm = 510mm (part height + offset + edge band offset(top) + edge band offset(bottom) - edge band thickness (top) - edge band thickness (bottom))
Image above zoomed in:
Option 2 - Offset of the shape and offset of the edge without subtracting the thickness of the edge band
Image above zoomed in:
Final shape: 1010x510
Contour: 1010x512
Note that the contour is 1mm larger at the top and bottom of the part, because the following calculation was made:
Final shape: 1010mm by 512mm
Largura: 1000mm + 10mm = 1010mm (largura da peça + sobrecorte)
Width: 1000mm + 10mm = 1010mm (shape width + offset)
Height: 500mm + 10mm + 1mm + 1mm = 512mm (shape height + offset+ edge band offset (top) + edge band offset (bottom)).
IMPORTANT: In the program shown above, up to 511mm is displayed at the top, as the part goes up to 510, and -1mm at the bottom, as the part starts at 0.

Option 3 - Plate offset without adding the edge band offset (Discounting edge band thickness)
Image above zoomed in:
Final shape: 1010x510
Contour: 1010x508
Note that the contour is 1mm smaller at the top and bottom of the part, because the following calculation was made:
Final shape: 1010mm by 508mm
Width: 1000mm + 10mm = 1010mm (part width + offset)
Height: 500mm + 10mm - 1mm - 1mm = 508mm (height of the shape+ offset - offset of the edge band(top) - offset of the edge band (bottom)).
IMPORTANT: In the program shown above, up to 509 mm is displayed at the top, because the part goes up to 510, and 1 mm is displayed at the bottom, because the part starts at 0.

Option 4 - Plate offset without adding the edgeband offset (without deducting the edgeband thickness)
Image above zoomed in:
Final shape: 1010x510
Contour: 1010x510
Note that the shape and the contour are exactly the same size, because the following calculation was made:
Final shape: 1010mm by 510mm
Width: 1000mm + 10mm = 1010mm (shape width + offset)
Height: 500mm + 10mm = 510mm (shape height + offset)
Image above zoomed in:
Option 5 - Edgeband offset without adding the plate offset (Discounting edgeband thickness)
Image above zoomed in:
Final shape: 1000x500
Contour: 1000x500
Note that the shape and the countor are exactly the same size, because the following calculation was made:
Final shape: 1000mm by 500mm
Width: 1000mm = 1000mm (shape width)
Height: 500mm + 1mm - 1mm = 500mm (shape height + edge band offset - edge band offset)
Image above zoomed in:
Option 6 - Edgeband offset without adding the plate offset (without discounting the thickness of the edgeband)
Image above zoomed in:
Final shape: 1000x500
Contour: 1000x502
Note that the contour is 1mm larger at the top and bottom of the part, because the following calculation was made:
Final shape: 1000mm by 502mm
Width: 1000mm = 1000mm (part width)
Height: 500mm + 1mm + 1mm = 502mm (height of shape+ edge band offset (top) + edge band offset (bottom)).
IMPORTANT: In the program shown, the top part is displayed up to 501 mm, because the part goes up to 500, and the bottom part is displayed at -1 mm, because the part starts at 0.

Option 7 - All options unchecked
Image above zoomed in:
Final shape: 1000x500
Contour: 1000x500
Note that the piece and the contour are exactly the same size, because the following calculation was made:
Final shape: 1000mm por 500mm
Width: 1000mm = 1000mm (shape width)
Height: 500mm = 500mm (shape height)
