Which risk increases when internal coolant flow halts during precision grinding of nickel-based superalloy turbine blades?

💡 Explanation

Wheel loading increases because the coolant no longer washes away debris and dissipates heat. This causes the abrasive particles to clog because of increased friction that introduces surface burnishing rather than efficient material removal; therefore blade material degrades as pressure grows.
