Abstract:
Computer controlled and monitored shot peening will become increasingly important, especially in the aerospace and automotive industries where verification is required to
document that a specific shot peening process and operation has been performed on a critical part. New equipment can be designed to fulfill exacting specifications, whereas
existing machinery can be extensively modified and modernized. In the latter, two major areas are identified. First, parameter conversion with signal conditioning is
needed. Second, signal recording with display and hard-copy facility is required. These modifications are shown for a three axis air-driven peening machine having a single
shot-delivery nozzle. Signals for pressure, for example, are easily obtainable. However, shot flow rate measurement requires use of special devices with monitoring and
signal conditioning capability. Devices for obtaining displacement signals are examined. Capabilities of hybrid recorder are presented. Using a modern hybrid recorder all
required standardized signals can be combined, programmed and the results printed out on a hard-coppy which can be interpreted in real time, if required, in a readily
understood format. Examples of printouts showing process irregularities are presented. Reasons for choice of hybrid recorder are explored.
