Abstract
In this study, groove-shaped cavities were created with Nd: YAG laser on ZAMAK 5 plates, which have been used frequently in the industry for many years. The necessary laser parameters have been optimized so that the created cavity floor has a homogeneous depth. The effects of the beam diameter, laser energy, shielding gas type, and duration of the single pulse of Nd: YAG laser used on the roughness in the cavity were tried to be optimized. It was used for optimization. According to the ANOVA table, the optimum parameters are “580µm, 7J, Nitrogen, 7 ms for spot diameter of spot, the energy of single spot, type of ambient gas and a spot of single pulse respectively. The Taguchi method also indicates how effective the laser parameters used are in obtaining the desired surface. It has been concluded that the ambient gas used is the most important parameter in this study. The effect rate was obtained as 74.90 %. Then, laser spot diameter and pulse energy and lastly pulse duration are fewer effective parameters respectively.

Abstract
Bu çalışmada uzun yıllardır sektörde sıklıkla kullanılan ZAMAK 5 plakalar üzerinde Nd:YAG lazer ile oluk şeklinde kaviteler oluşturulmuştur. Oluşturulan kavite tabanının homojen bir derinliğe sahip olması için gerekli lazer parametreleri optimize edilmiştir. Kullanılan Nd:YAG lazerin ışın çapı, lazer enerjisi, koruyucu gaz tipi ve tek atım süresinin kavite pürüzlülüğü üzerindeki etkileri optimize edilmeye çalışılmıştır. ANOVA tablosuna göre, spot çapı, tek spot enerjisi, ortam gazı türü ve tek darbe spotu için optimum parametreler sırasıyla “580µm, 7J, Nitrogen, 7 ms'dir. Taguchi yöntemi, kullanılan lazer parametrelerinin istenilen yüzeyin elde edilmesinde ne kadar etkili olduğunu da göstermektedir. Kullanılan ortam gazının bu çalışmada en önemli parametre olduğu sonucuna varılmıştır. Etki oranı %74.90 olarak elde edilmiştir. Daha sonra sırasıyla lazer spot çapı ve atım enerjisi ve son olarak atım süresi daha az etkili parametrelerdir.
