Abstract

AISI P20 plastic mold steel is a material generally used in the mold industry. In mold manufacturing, quality holes are needed because continuity of product quality, high repetitive work, and maximum mold life are required. Additionally, boring tools are used in the manufacture of engine block cylinder housings in the automotive industry. Boring operations play a vital role in obtaining the final quality of pre-drilled holes. The cutting insert of the boring tool contacts the hole wall at a single position relative to the hole axis. This situation causes the cutting torque to result in the highest force in the boring process. Therefore, one of the most critical indicators of hole quality is boring torque. The aim of the present study is to deeply analyze the impacts of coating type, cutting edge radius, feed rate, cutting speed, and radial depth of cut parameters on the boring torque in the precision boring process of AISI P20 material on a vertical machining machine. For this purpose, graphics, Taguchi, and Anova methods were used. As a result, while the radial depth of cut was determined as the most effective parameter on the boring torque, the coated cutting insert produced lower torque values. As a result of the calculated regression equations, an R2 value of 97.47% was obtained.

Özet

AISI P20 plastik kalıp çeliği, genellikle kalıp sektöründe kullanılan bir malzemedir. Kalıp imalatında ise ürün kalitesinin sürekliliği, yüksek tekrarlı çalışma ve maksimum kalıp ömrü gerektiğinden kaliteli deliklere ihtiyaç bulunmaktadır. Ayrıca otomotiv sektöründe motor bloğu silindir yuvalarının imalatında baralar kullanılmaktadır. Önceden delinmiş deliklerin nihai kalitesinin elde edilmesinde baralama operasyonları önemli bir yer tutmaktadır. Delik eksenine göre baranın kesici ucu tek noktada delik duvarı ile temas halindedir. Bu durum ise baralama işleminde kesme torkunun en yüksek kuvvet olarak sonuçlanmasına neden olmaktadır. Dolayısıyla delik kalitesinin en önemli göstergelerinden birisi baralama torkudur. Mevcut çalışmada AISI P20 malzemesinin dik işleme tezgahında hassas baralanması işleminde kaplama tipi, kesici uç radüsü, radyal kesme derinliği, kesme hızı ve ilerleme miktarı parametrelerinin baralama torkuna etkilerinin derinlemesine araştırılması amaçlanmıştır. Bunun için grafikler, Taguchi ve Anova yöntemleri kullanıldı. Sonuç olarak baralama torku üzerinde en etkili parametre olarak radyal kesme derinliği tespit edilirken, kaplamalı kesici uç daha düşük tork değerleri meydana getirmiştir. Hesaplanan regresyon eşitlikleri sonucu %97,47 oranında bir R2 değeri elde edilmiştir.
