Aşındırıcılı su jeti (AWJ) ile işlemede enerji kaybı olayının deneysel tahmini, karakterizasyonu ve modellenmesi-yapılan çalışmaların değerlendirilmesi

Malzemelerin aşındırıcılı su jetiyle işlenmesinde, enerji kaybı süreçleri önemli bir rol oynar. Bu süreçler, özgül enerji ve çizgisel izler şeklinde oluşan yüzey topografyası gibi ekonomiklik ve kaliteyle ilgili parametreleri etkiler. Aşındırıcılı su jeti ile, farklı işleme şartlarında çeşitli malzemeler üzerinde yapılan deneyler, işleme derinliği ve enerji kaybı arasında doğrusal olmayan bir ilişkinin varlığını göstermektedir. Bu ilişki, kesme önü geometrisinin parabolik modeline dayanan ikinci dereceden bir eşitlikle, etkin bir biçimde tanımlanabilmektedir. Bu makalenin amacı, aşındırıcılı su jetiyle işlemede enerji kaybı olayının deneysel tahmini, karakterizasyonu ve matematiksel olarak modellenmesine odaklanmış önceki çalışmaların genel bir değerlendirmesini yapmaktır.

Experimental estimation, characterization and modelling of energy dissipation phenomenon in abrasive water jet cutting- a review of previous studies

Energy dissipative processes play a key role in abrasive water jet machining of materials. They influence the economical and qualitative parameters, of the process such as specific- energy and surface topography with striation marks. Experiments on sevaral materials cut by abrasive water jets under different cutting conditions show that the relation between the depth of cut and the energy dissipation is non-linear. This relation can effectively be described by a second order equation based on the parabolic model of the cutting front geometry. This paper aims to make an evaluation of previous studies focused on experimental estimation, characterization and mathematically modelling of energy dissipation phenomenon in abrasive water jet cutting.
