Surface ripples occur on hardened steel after grinding due to which mechanism?

💡 Explanation

Regenerative chatter vibration induces surface ripples because the grinding wheel's periodic displacement excites resonant frequencies, resulting in self-excited movement and uneven material removal. Therefore, chatter vibration causes observed waviness rather than fracturing or expansion variations during high-precision grinding.

• Which outcome occurs when a solar panel experiences shading?
• Which outcome occurs when the expansion valve supplying an HVAC evaporator malfunctions and restricts refrigerant flow?
• Which risk increases when post-tensioned concrete slab tendons experience grout voids after stressing?
• Which risk increases when a hydraulic actuator's quick exhaust valve fails closed during rapid cycling?
• Which risk increases when a three-phase circuit breaker trips due to single-phasing in an induction motor load?
• Which outcome occurs when a MOSFET, used in a high-frequency power amplifier, experiences gate-oxide breakdown?
