Which risk increases substantially because using an excessively hard grinding wheel in a CNC cylindrical grinding machine?

💡 Explanation

Thermal cracking increases because the grinding wheel’s abrasive grit dulls quickly which causes increased friction and heat generation, rather than efficiently shearing material. Therefore, localized heating exceeds the material's thermal limits; alternative options address wheel wear or material removal rates.
