Tip 1
(1 for vertical straight line)
Add a radius to internal vertical edges
R>1/3D
Tip 2
(2 many cavities to limit)
Limit depth of cavities
Tip 3
("3" is the limit of threads)
Limit length of threads
(1/2 or more of diameter of unthreaded length at bottom of hole)
(Threads have max of 3x length of hole diameter)
Tip 4
(4 holes and threads standard drill and tap size)
Use standard drill and tap size for holes and threads
(diameters 10mm up add 0.1mm)
(diameters over 10mm ass 0.5mm)
Tip 5
Increase thickness of thin walls
(metal, thicker the better, over 0.8mm)
(plastic, keep minimum thickness)
Tip 6
Avoid small features, Width to Height ratio
Tip 7
Minimize number of machine setups
(or separate into multiple geometries)
Tip 8
Center axial symmetry, avoid 3-axis and 5-axis
Tip 9
Add tolerances only when necessary, use a single datum as reference
Tip 10
Laser over CNC engraving (for text, size and add vector for accuracy)
Tip 11
Avoid multiple surface finishes
Tip 12
Account for bank size and material removal
Tip 13
Machinability, what's the best material
(aka soft metals)
Tip 14
Consider price of bulk material
Tip 15
Buy bulk, economic advantage in material
