Peening a surface spreads it plastically, causing changes in the mechanical properties of the surface. Its main application is to avoid the propagation of microcracks in a surface. By putting a material under compressive stress, shot peening prevents such cracks from propagating. Shot peening is often called for in aircraft repairs to relieve tensile stresses built up in the grinding process and replace them with beneficial compressive stresses. Depending on the part geometr… Splet06. feb. 2024 · Roles and Types of Shot Peening Operator There are several types of shot peening operator, including: Numerical Control Operator Role: A Numerical Control … SpletShot peening is a mechanical surface treatment where a stochastic stream of particles impinges the surface to impart favorable compressive residual stresses by severe plastic deformation (Fig. 2).
