Abstract

Udrills are indexable insert drill commonly used in drilling operations. It is estimated that the market share among drilling tools is around 53%. They are produced in the same nominal diameter but in different lengths. There are usually two cooling holes, one behind the central insert and the other behind the peripheral insert. However, in some Udrills, an extra third cooling hole is drilled by the manufacturer. In this study, the effects of different length/diameter ratios, extra coolant hole and drilling parameters on thrust force, torque and spindle load were investigated in order to determine the effect of differences in U drills on hole drilling. AA 2024-T351 was drilled to a depth of 40mm using Udrills with a body diameter of 20mm. A total of 4 Udrills (3D, 4D, 4De, 5D) were used. Three feed rates (0.06, 0.09, 0.12mm/rev) and three cutting speeds (200, 250, 300m/min) were used in the experiments. According to the Anova analysis, it was concluded that while the length/diameter ratio of Udrills had an effect of 56.97% on thrust force and 21.46% on spindle load, it was not effective for torque. The 4De Udrill with extra coolant hole gave 34.2% higher thrust force, 0.3% higher torque value and 26.53% lower spindle load compared to the 4D Udrill without extra coolant hole.

Farklı Özelliklere Sahip U Matkapların İtme Kuvveti, Tork ve İş Mili Yüküne Etkisinin İncelenmesi

Abstract

U matkaplar delik delme operasyonlarında yaygın olarak kullanılan değiştirilebilir uçlu kesici takımlardır. Delme takımları içerisinde pazar payının %53 civarında olduğu tahmin edilmektedir. Aynı nominal çapta ancak farklı uzunluklarda üretilmektedirler. Genellikle biri merkezi ucun diğeri ise çevresel ucun arkasında olmak üzere iki tane soğutucu delik bulunmaktadır. Ancak bazı U matkaplarda üretici tarafından ekstra üçüncü bir soğutucu delik açılmaktadır. U matkaplarda bulunan bu farklılıkların delik delmeye etkisini tespit etmek amacıyla, bu çalışmada farklı uzunluk/çap oranlarının, ekstra açılmış soğutucu deliğin ve delme parametrelerinin itme kuvveti, tork ve iş mili yüküne etkisi araştırılmıştır. 2024-T351 alüminyum alaşımı, gövde çapı 20 mm olan U matkaplar kullanılarak 40 mm derinliğinde delinmiştir. Farklı uzunluk/çap oranlarının etkisini incelemek için 3 adet (3D, 4D ve 5D), ekstra soğutucu deliğin etkisini incelemek için ise 1 adet (4De) olmak üzere toplam 4 adet U matkap kullanılmıştır. Deneylerde, üç adet ilerleme miktarı (0.06, 0.09, 0.12 mm/rev) ve üç adet kesme hızı (200, 250, 300 m/min) kullanılmıştır. Anova analizine göre U matkapların uzunluk/çap oranı itme kuvvetinde %56.97, iş mili yükünde %21.46 etkiye sahipken tork için etkili olmadığı sonucuna varılmıştır. Ekstra soğutucu deliği bulunan 4De U matkap, bulunmayan 4D U matkaba göre itme kuvvetinde %34.2, tork değerinde % 0.3 oranında yüksek, iş mili yükünde %26.53 düşük bir değer vermiştir.
