Abstract
Parça geometrisi ve malzeme
özellikleri dikkate alındığında shot peening (SP, bilyeli dövme) süreci parçaya
özgü imalat süreci tasarımı ve parametre tanımı gerektirmektedir. Bu, malzemenin
mekanik ve yüzey özelliklerini iyileştirmeyi amaçlayan mekanik bir süreçtir. Özellikle
dinamik yükler altında çalışan, burulma ve burkulmaya zorlanan parçalarda
kullanılmaktadır. Dolayısıyla sürece birçok parametre etki etmektedir. Bu
çalışmada, adım motorunun iki farklı açısal değerinde bilyeli dövme uygulama
süreleri bağımsız parametreler olarak alınmış ve parça üzerinde konumlandırılan
dört farklı Almen plakasından ölçülen deformasyon değerleri incelenmiştir. Ön
deneylerde elde edilen bulgular doğrultusunda süreler üzerinde bazı
değişiklikler öngörülmüştür. Tasarlanan ikinci deney seti sonrasında Almen
plakalarının sonuçlarında istenen aralığa doğru bir iyileşme sağlanmıştır. Bilyeli
dövme sürecinin daha fazla bağımsız değişken ile incelenmesi gerektiği sonucuna
varılmıştır.

Abstract
When part geometry and
material properties are taken into consideration, shot peening (SP) process is required
part specific process design and parameter definition. This process is a
mechanical process aiming to improve the mechanical and surface properties of
the material. It is particularly used for the parts which operate under dynamic
loads and subjected to torsional and buckling forces. Therefore, many
parameters are affected the process. In this study, shot peening durations at
two different angular values of the stepper motor were taken as independent
parameters and deformation values measured from 4 different Almen strips
located on the part were investigated. In consideration of the findings
obtained in the preliminary experiments, some changes on the peening durations
are suggested. After the second set of designed experiments, some improvements
in the direction of the appropriate range were achieved in the results of the
Almen strips. It was concluded that the shot peening process should be examined
with a greater number of independent variables.
