Aşındırıcılı su jetiyle (AWJ) kesmede elde edilen yüzey özellikleri yapılan çalışmaların değerlendirilmesi

Kesme uygulamalarında, oksijen kaynağı ile kesmeden su jetine kadar bir çok yöntem kullanılmaktadır. Bir ileri teknoloji ürünü olan su jeti, bu yöntemlerin en verimli olanıdır. Yeni bir üretim yöntemi olarak aşındırıcılı su jeti (AWJ), işlenmesi güç malzemelerin işlenmesinde etkili bir yöntemdir. Garnet, alüminyum oksit veya silisyum karbür gibi aşındırıcıların yüksek hızlı bir su jetiyle ivmelendirildiği ve bir AWJ nozulu üzerinden işlenecek malzemeye yönlendirildiği bu işleme yöntemi, son zamanlarda kullanıma sunulan güncel işleme metotlarından biridir. Yöntemin endüstriyel uygulamalarda yaygın olarak kullanılmaya başlamasıyla yapılan araştırmalar da bu yöntemle elde edilen yüzey özellikleri üzerinde yoğunlaşmıştır. Mekanik tasarım ve üretimde çok önemli olan yüzey topografyasının karakterizasyonu, pek çok mühendislik alanında giderek daha da önem kazanmaktadır. Bu nedenle bu çalışmanın amacı, aşındırıcılı su jetiyle elde edilen yüzeylerin yüzey topografyası, yüzey kalitesi ve kesik modeli üzerine odaklanmış çalışmaların bir değerlendirilmesini yapmaktır

Surface characteristics attained in abrasive water jet (AWJ) cutting a brief evaluation of previous studies

In the cutting applications, several methods are being used varying from flame cutting to waterjet. Amongst these, the waterjet which is the product of advanced technology is the most effective one. As a new manufacturing process, abrasive water jet (AWJ) machining has been very effective in machining difficult-to-machine materials. This cutting technique is one of the most recently introduced machining methods in which an abrasive such as garnet, aluminum oxide or silicon carbide is accelerated by a thin stream of high velocity waterjet and directed through on AWJ nozzle towards the target material to be machined. The studies also have been concentrated on surface characteristics generated by this process become widespreadly in industrial applications surface topography is crucial to mechanical design and manufacturing and characterization of surface topography has become increasingly important in many engineering fields. For this reason, the aim of this paper, to make an evaluation of studies focused on surface topography, surface quality and kerf model of abrasive waterjet generated surfaces.
