Bu çalışmada nikel bazlı bir süperalaşım olan Inconel 718’ in delinmesinde, kriyojenik soğutmanın delme performansına etkileri deneysel olarak araştırılmıştır. Delme deneyleri, kaplamasız ve TiAlN kaplamalı karbür matkaplar kullanılarak sabit bir kesme hızı (10 m/dk) ve ilerleme (0,02 mm/dev) ile kriyojenik, geleneksel kesme sıvısı ve kuru şartlar altında gerçekleştirilmiştir. Soğutma/yağlama şartlarının ve kaplama malzemesinin etkileri, eksenel kuvvet, tork, maksimum sıcaklık, çapak oluşumu, talaş oluşumu, yüzey altı deforme olmuş tabaka derinliği, mikrosertlik değişimi ve ortalama yüzey pürüzlülüğü değerleri açısından incelenmiştir. Kriyojenik soğutma, sıcaklık değerlerini önemli derecede düşürmüştür. Genel olarak kriyojenik şartlarda daha düşük yüzey altı deforme olmuş tabaka kalınlığı ve delik girişinde daha az çapak oluşumu elde edilmiştir. Ancak deney sonuçları kriyojenik soğutmanın eksenel kuvvet ve tork değerlerini arttırdığını ve hızlı takım aşınmasına sebep olduğunu göstermiştir. Buna bağlı olarak çıkış çapak yükseklikleri de artmıştır. İyi yüzey pürüzlülüğü değerleri ve düşük takım aşınması kesme sıvısı kullanımıyla elde edilmiştir.
