gear grinding

Cogs scraping together

Gear grinding is a machining process that uses an abrasive wheel to finish gear teeth to precise dimensions and smooth surfaces.

In automotive contexts, gear grinding refers to the harsh metallic sound when shifting a manual transmission without properly matching engine and gear speeds: I could hear him grinding gears from across the parking lot.

The phrase sometimes describes any friction between incompatible systems or people.
