Optimization of Process Parameters in Drilling Process of Forged Ecofriendly Low-Lead Brass Alloy

Öz

Bu araştırma, düz bottom drill kesme takımı kullanılarak dövülmüş çevre dostu kurşunsuz pirinç alaşımının yüzey bütünlüğü özellikleri üzerindeki delme işleminin deneysel incelemesini ve ideal çözüme (TOPSIS) benzerlik ile sıra tercihi ve Grey orantı analiz tekniklerinin uygulanmasını ile çoklu çözüm için parametrik optimizasyon sunmaktadır. Boyutsal doğruluk, işleme süresi, kesme kuvvetleri ve deliklerin yüzey kalitesi hakkındaki deneysel veriler, işlenmiş numunelerin yüzey bütünlüğünü değerlendirmek için analiz edilimiştir. Parametrelerin önemini % 95 güven aralığında elden çıkarmak için varyans analizi (ANOVA) gerçekleştirilmiştir. Her iki optimizasyon aracı da aynı kesme parametreleriyle sonuçlanmıştır. Elde edilen talaş formlarının analizi optimizasyon sonuçlarını doğrulamıştır.

Optimization of Process Parameters in Drilling Process of Forged Ecofriendly Low-Lead Brass Alloy

Öz

This research presents an experimental investigation of the drilling operation on surface integrity characteristics of forged eco-friendly lead-free brass alloy using flat bottom drill cutting tool and application of techniques for order preference by similarity to ideal solution (TOPSIS) and Grey relational analysis methods in parametric optimization for solving multiple criteria (objective) process. Experimental data on dimensional accuracy, machining time, cutting forces, and the surface quality of the holes are analyzed to evaluate surface integrity of machined specimens. Analysis of variance (ANOVA) was performed to dispose the significance of the parameters at a %95 confidence interval. Both optimization tools resulted in the same cutting parameters. The analysis of the obtained chip forms verifies the optimization results.
