Which outcome occurs when the grinding wheel's coolant supply fails during precision camshaft lobe grinding?

💡 Explanation

Thermal cracks appear because rapid temperature increases occurs due to frictional heat overpowering the process during grinding. Consequently, thermal expansion stresses yield to cracking, therefore the camshaft lobe surface suffers micro-fracturing rather than maintaining dimensional stability and integrity.
