Production-related constraints
Here, you will find information on constraints for various milling or engraving objects that have emerged over time through experience, as well as some related design tips.
Limitation on drill hole diameters and corner radii
The smallest tool available, a cutter with a 1 mm diameter, provides the following limitations:
Drill hole diameter at least 1.0 mm
Inner corner radius at least 0.5 mm
Note that drill holes with a diameter of
1 mm may not be made deeper than 4.8 mm,
those with a diameter of 1.5 mm may not be made deeper than 5.8 mm,
and those with a diameter of 2 mm may not be made deeper than
7.8 mm.
As of 3 mm, there are no more constraints.
Standard corner radius
If specifying inner corner radii is not absolutely essential, an optimal price can be achieved by selecting the typically specified corner radius of 1.5 mm. This can be cut using the 3 mm cutter. This cutter is also used to mill the outer contour, which means no cost-incurring tool change is made.
Overlapping objects
In principle, positioned objects may overlap as you like. This makes it possible to create special contours both inside and along the base panel’s edge. The following should be noted here:
Objects may not project more than 3 mm outside the edge of the base panel (otherwise the clamping of the base panel will be inadmissibly impaired)
Engravings should not overlap with drill holes, cut-outs, and so on, as the greater the width of the engraving, the greater the risk that the in-fill may “leak.”
Neighboring objects
If large-scale cut-outs are placed in tight proximity to one another, so that they are only divided by a narrow strip of material, they could start to vibrate during the milling process and break. The distance between cut-outs should therefore be at least 3–4 mm.
