AA 7705 Alüminyum Alaşımının Aşındırıcı Su Jeti ile Delinmesinde Traverse Hızının Geometrik Toleranslara Etkisinin Araştırılması
Bu çalışmada, aşındırıcı su jeti ile AA7075 alüminyun alaşımının delinmesinde nozul travers hızının geometrik toleranslara etkisi araştırılmıştır. Delikler 10 farklı nozul travers hızı (10, 16, 24, 34, 45, 55, 65, 75, 90 ve 110 mm/dak) kullanılarak 10 mm çapında delinmiş ve diğer parametreler sabit tutulmuştur. Farklı nozul travers hızları kullanılarak açılan deliklerin dairesel ve silindiriklik sapması CMM kullanılarak ölçülmüştür. Nozul traverse hızı artışının silindiriklik ve dairesellikten sapma değerlerinin artışına neden olduğu tespit edilmiştir. Sonuç olarak, artan nozul traverse hızı birim yüzeye temas eden aşındırıcı miktarını azaltmakta ve istenilen geometri doğrultusunda kesme işlemi gerçekleşmemektedir.
A Study on the Effect of Traverse Speed on Geometric Tolerances in Abrasive Waterjet Drilling of Aa7075 Aluminium Alloy
In this study, the effect of nozzle traverse speed on the geometric tolerances in the drilling of AA 7075aluminum alloy by abrasive water jet was investigated. Holes were drilled with a diameter of 10 mmusing 10 different nozzle traverse speeds (10, 16, 24, 34, 45, 55, 65, 75, 90 and 110 mm/min) and theother parameters were kept constant. Circularity and cylindricity deviation of the holes drilled usingdifferent nozzle traverse speeds was measured using a CMM. It was found that the increase in nozzletraverse speed results in increased deviation values from circularity and cylindricity. As a result,increased nozzle traverse speed reduces the amount of abrasive contacting the unit surface and the cuttingprocess does not occur in accordance with the desired geometry.
