Which outcome occurs when thermal distortion affects precision grinding processes?

💡 Explanation

Increased surface roughness results because thermal distortion causes uneven material removal during grinding; the grinding wheel's position deviates dynamically due to heat build-up, introducing irregularities leading to a rougher surface, therefore increasing roughness, rather than improving hardness.
