Changes in aerospace machining standards

But recently, there’s been a push for tighter tolerances in aerospace components due to new safety regulations. I’m curious how everyone is adapting to these changes, especially regarding the sourcing of specialized materials. Has anyone found particularly effective techniques or tools to maintain these precision levels?
