INCONEL 718'İN DELİNEBİLİRLİĞİNİN ARAŞTIRILMASI

open access: yes, 2007
Bu çalışmanın amacı, Inconel 718'in delinebilirliği için kuru kesme koşulları altında optimum delme şartlarını tespit etmektir. Bu amaçla, süper alaşım Inconel 718'in kaplamalı ve kaplamasız karbür matkaplarla delinmesi esnasında kesme parametrelerinin; kesme kuvvetleri, yüzey pürüzlülüğü, delik kalitesi ve talaş oluşumu üzerindeki etkisi analiz ...

Laser balancing system for high material removal rates [PDF]

open access: yes
A laser technique to remove material in excess of 10 mg/sec from a spinning rotor is described. This material removal rate is 20 times greater than previously reported for a surface speed of 30 m/sec. Material removal enhancement was achieved by steering
