Stop Designing Like a Beginner | 6 Advanced DFMA Tips

Bolt Sizing Optimization00:00:59

Standardizing bolt sizes within a single part reduces tool change frequency during machining, significantly cutting down on setup time and production costs.

Material Standardization00:03:09

Minimize variation in material thicknesses to simplify inventory and machining processes. Selecting thicknesses closer to standard raw material sizes prevents unnecessary material removal costs.

Guided Adjustment Mechanisms00:06:08

Avoid purely slotted holes for adjustments, as they often lead to uncontrolled angular deflection. Instead, use keys or parallel guides to ensure precise, straight-line movement.

Undercuts for Assembly00:07:27

Include undercuts at the steps of shafts to provide clearance for machining tool radii. This ensures mating components, such as bearings, can sit perfectly flat against the shoulder.

Efficient Maintenance Design00:08:35

Design covers and interchangeable parts with slotted holes and large openings to allow for quick removal or replacement by simply loosening screws rather than removing them entirely.
