Abstract
Fiber-reinforced non-oxide ceramics have experienced increased interest due to their use as high-performance materials in aerospace. Since aerospace components are classified as safety-critical components, damage-free grinding of fiber-reinforced non-oxide ceramics components is inevitable. Due to two-phase material behavior, damage-free grinding of fiber-reinforced non-oxide ceramics is hard to achieve. To analyze the material removal behavior during grinding, the time and cost consuming analogy process single grain cutting is performed. To save time and cost, it is desirable to simulate the analogy process numerically. In this paper, the Smooth Particle Hydrodynamic (SPH) method is used to simulate single-grain cutting of fiber-reinforced non-oxid ceramics.
