Drilling Vanadis 4E with Coated Drills; Examination of Wear, Surface Roughness, and Chip Formation

Abstract

Vanadis 4E is a versatile powder metallurgical tool steel widely used in today's market with high wear resistance and excellent yield properties. Drilling operations applied to materials are one of the operations commonly used in the machining industry. In drilling operations, coated or uncoated drills are used, which may vary according to the material used. This study applied drilling operation to Vanadis 4E powder metallurgical steel with TiN-coated HSS drills. In the study, Drills with diameters of 5, 8.5, and 10.5 mm, cutting speeds of 22, 23, and 24 m/min, and feed rates of 0.10, 0.12, and 0.14 mm/tooth was used. Nine experiments were carried out using the Taguchi L9 orthogonal array. After the experiments, the material was cut from the holes, and the roughness values were measured from the inner surfaces of the holes. In addition, hardness measurements were made from the material surfaces around the holes. The wear conditions of the drills used in the experiments were examined with an optical microscope after the experiment. The formations after each experiment were also examined. The best roughness value was obtained with the 5 mm diameter drill in the 1st experiment, the best roughness value was obtained in the experiments carried out with the 8.5 mm diameter drill in the 6th experiment, and the best roughness value was obtained in the 7th experiment for the 10.5 mm diameter drill. When the wear in the drills was evaluated, it was observed that the side surface and radial wear occurred.

Vanadis 4E’nin Kaplamalı Matkaplarla Delinmesinde; Aşınma, Yüzey Pürüzlülüğü ve Talaş Oluşumunun İncelenmesi

Abstract

Vanadis 4E, yüksek aşınma direncine ve çok iyi sünme özelliğine sahip, günümüz piyasasında yaygın olarak kullanılan çok yönlü toz metalurjik takım çeliğidir. Malzemelere uygulanan delme operasyonları, talaşlı imalat sektöründe yaygın olarak kullanılan işlemlerden biridir. Delme operasyonlarında, kullanılan malzemeye göre değişiklik gösterebilen kaplamalı veya kaplamasız matkaplar kullanılmaktadır. Bu çalışmada Vanadis 4E toz metalürjik çeliğe TiN kaplamalı HSS matkaplarla delme operasyonu uygulanmıştır. Çalışmada; 5, 8.5 ve 10.5 mm çapta matkaplar, 22, 23 ve 24 m/dak kesme hızları ve 0.10, 0.12 ve 0.14 mm/diş ilerleme oranları kullanılmıştır. Taguchi L9 ortogonal dizisi kullanılarak 9 deney yapılmış, deneyler sonrası malzeme deliklerden kesilerek, delik iç yüzeylerinden pürüzlülük değerleri ölçülmüştür. Ayrıca, deliklerin çevresindeki malzeme yüzeylerinden sertlik ölçümleri yapılmıştır. Deneylerde kullanılan matkapların deney sonrası optik mikroskop ile aşınma durumları incelenmiştir. Her bir deney sonrası oluşumları da incelenmiştir. 5 mm çaptaki matkapla en iyi pürüzlülük değeri 1. deneyde, 8.5 mm çaptaki matkapla yürütülen deneylerde en iyi pürüzlülük değeri 6 numaralı deneyde ve 10.5 mm çaptaki matkapta ise en iyi pürüzlülük değeri 7. deneyde elde edilmiştir. Matkaplarda ki aşınmalar değerlendirildiğinde, yan yüzey ve radyal aşınmaların oluştuğu görülmüştür.
