Abstract:
A system for shot peening that includes an enclosure in which are provided a workpiece W to be shot peened and a nozzle for projecting the shot particles. A memory stores
data for maximizing the anticipated shot-peening intensity at the workpiece based on the predetermined conditions of the shot peening. Then a calculating circuitry
determines the conditions of the shot peening to be carried out in the system to maximize an anticipated shot-peening intensity at the workpiece based on the stored data
from the memory and the selected type of the shot-peening process to be applied to the workpiece before the shot particles have been actually projected. The nozzle is then
actuated under the determined conditions such that it projects the shot particles and directs them onto the workpiece. The shot-peening intensity of the actually projected
shot particles at the workpiece is measured by a measuring device. Then a calibration circuitry controls the mass-flow rate of the shot particles and the pressure or the
flow rate of the compressed air to maximize the measured shot-peening intensity based on the stored data such that the nozzle projects the shot particles under the corrected
and controlled conditions.
