$$T_assy = \sqrt\sum_i=1^n (C_i \cdot T_i)^2$$ rss method tolerance analysis
$$T_assy = \sqrt0.20^2 + 0.10^2 + 0.15^2$$ $$T_assy = \sqrt0.04 + 0.01 + 0.0225$$ $$T_assy = \sqrt0.0725$$ $$T_assy = 0.269 \text mm$$ You can use this content for a blog
Unlike the worst-case (linear) method which adds all tolerances arithmetically, RSS assumes that not all components will be at their extreme limits simultaneously. It is based on the statistical principle that variations follow a . rss method tolerance analysis
