Design suggestions

Minimum wall thickness

0.5 mm

Minimum end mill size

0.8 mm (0.03 in)

Minimum drill size

0.5 mm (0.02 in)

Maximum part size

1200 x 500 x 152 mm [x,y,z] (milling)
152 x 394 mm [d,h] (Lathe)

Undercut

Square outline, full radius, dovetail outline

Radius: Depth

The depth must not exceed 12 times the drill diameter.
For end mills, the depth must not exceed 10 times the diameter of the tool.

Cost saving tips

In order to reduce costs, please limit the number of parts set, the number of check sizes or strict tolerances, and the deep cavity with a small radius.
