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