“…While more than 100 million gallons of coolant are used in the US each year, nearly 12 million workers face the potential dangers of these cutting fluids. When all these reasons are listed, both researchers and industrial organizations have been making efforts to reduce the use of cutting fluid and find an alternative recently, due to the impact of the use of coolant on production costs and its harmful effects on the environment and human health [13]. Çakır, in his studies; stated that chemicals such as iron sulphate and acid are used to separate waste cutting oil and emulsion cutting fluids.…”

“…In terms of surface roughness, they explained that they achieved the best value in the use of vegetable cutting oil. The reason for this it is seen that vegetable oil has lower viscosity than mineral oil [13]. Sarıkaya et al used the MQL system of vegetable oil, synthetic ester mineral oil and only mineral oil to spray the Haynes 25 superalloy in the turning process with an uncoated carbide cutting tool.…”

In the study, various vegetable oil and water mixtures were used as cutting fluid to be tested in machining. These fluids have been used as an alternative to cutting fluids made from synthetic and semi-synthetic oils, which have harmful effects on nature and humans, and their performance has been investigated. As vegetable oil, Soy, Sunflower and Canola oils were mixed with water each and separate cutting fluids were obtained. Vegetable oil and water were mixed at 7 % and 93 %, respectively, and turned into a homogeneous liquid. Dry cutting and commercial cutting fluid using for cutting was also performed in comparison turning. In the study, AISI 4140 steel was processed on a CNC turning machine using an uncoated carbide insert. In all experiments, the cutting speed was kept constant as 200 m/min, the feed rate as 0,2 mm/rev, and the depth of cut at 1 mm. Cutting fluids were used in two different ways in experiments as liquid and 4 bar pressure spraying. As a result of the experiments, tool wear and surface roughness values were studied. The best results in all processing terms have been found in experiments with pressurized spraying of a mixture of canola oil and water. The surface roughness value was measured as 1,35 μm and the tool wear value was measured as 0,13 mm. The worst values were obtained in experiments carried out under dry cutting condition. Surface roughness value was measured as 2,31 μm and tool wear value was measured as 0,24 mm.

Günümüzde kültür turizmi hem çeşitlilik göstermesi bakımından hem de dünya genelinde olan ilginin artmasından dolayı önde gelen turizm aktiviteleri arasında yer almaktadır. Kayseri’nin köklü bir geçmişinin olması ve birçok medeniyete ev sahipliği yapması birçok uygarlığın kültürel izlerinin görülmesini sağlamaktadır. Bu kültürel çeşitlilik kültür turizmi bakımından önem taşımaktadır. Araştırmanın amacı Kayseri’nin bu kültürel zenginliğinin yerel halk, ziyaretçiler, yerel yönetici ve esnaf gibi farklı paydaşların görüşleri doğrultusunda değerlendirilmesine dayanmaktadır. Çalışmada nitel araştırma yöntemi kullanılmıştır. Yarı yapılandırılmış görüşme formuna dayalı olarak amaçlı örneklem tekniği ile farklı paydaşlardan olan 15 katılımcı ile derinlemesine görüşmeler gerçekleştirilmiş. Görüşmeler NVivo 10 programı ile kodlar oluşturulup analiz edilmiştir. Araştırma sonucunda Kayseri’nin ilkçağdan günümüze kadar birçok farklı medeniyetlerin kültürel değerlerini bulundurması açısından kültür turizmi potansiyeli bakımından önem taşıdığı belirlenmiştir. Bunun yanında alanda kültür turizm faaliyetlerinin istenen düzeyde olmadığı, bazı kültürel değerlerin turizme kazandırılması gerektiği ve alandaki kültür turizminin festivaller ve gastronomi turizmi gibi çeşitlendirilmesinin alanda turizmin gelişmesine katkı sağlayacağı sonucuna ulaşılmıştır.
