Holes with a diameter that are too small to cut, are marked. In practice, this means either a small hole or a marking point to indicate the position of the hole.
Starting points can be specified in Sophia®. 247TailorSteel determines the position if the starting points have not been specified.
The starting point must be drawn at least 3 mm outside of the entity or at the top (see image). A distance of at least 5 mm applies to sheets that are thicker than 10 mm.
When placing the starting point, note that there must be space perpendicular to the starting point for insertion. A starting point must therefore not be placed in the middle of a narrow slot.
When cutting holes into corners, specific hole diameters are maintained. The table below shows the desired hole diameter according to sheet thickness.
For example, a sheet thickness of 0.5 mm to 3 mm should have a hole diameter of 1 mm. At the opposite end of the spectrum, a sheet thickness of 15 mm to 25 mm should have a hole diameter of 4 mm. See the table for a complete overview.
Plate thickness | Hole diameter |
---|---|
0.5 t/m 3.0 mm | 1.0 mm |
4.0 t/m 6.0 mm | 1.5 mm |
8.0 t/m 12.0 mm | 2.0 mm |
15.0 t/m 25.0 mm | 4.0 mm |
Edging sharp corners
≤ 3 mm: 0,3 mm
> 3 mm: 0,1 x sheet thickness
Holes may only be located on the top (blue side) of the product. Holes drawn in the thickness of the material (see illustration) cannot be recognised by Sophia and may cause incorrect hole calculations.
247TailorSteel only engraves functionally, for positioning or identification. Only the upper side of the sheet can be engraved. Foil-coated materials cannot be engraved.
Please refer to STEP and/or DXF/DWG file specifications for character specifications.
Dimensional tolerances of cut contours. Cutting is in accordance with the ISO9013 norm, unless stated otherwise in the table below.
