SERBEST FORMLU İNCE CİDARLI AA 5083-H111 ALAŞIMININ FREZELENMESİNDE KESME PARAMETRELERİNİN FORM HATASINA ETKİSİNİ ÜÇ BOYUTLU KOORDİNAT ÖLÇME VE LAZER TARAMA İLE KARŞILAŞTIRILMASI
Abstract
Bu makale, serbest formlu ince cidarlı AA 5083-H111 alaşımının frezelenmesinde kesme parametrelerinin form hatasına etkisi üç boyutlu koordinat ölçme (CMM) ve lazer tarama (LS) sonuçlarının karşılaştırılmasına odaklanılmıştır. Deneyler Taguchi L32 ortogonal dizisi kullanılarak hazırlanan deney tasarımına göre kaplamasız karbür kesici takım kullanılarak kuru işleme şartlarında CNC dik işleme merkezinde yapıldı. CMM ve LT için form hatalarını etkileyen en önemli kesme parametrelerini belirlemek için varyans analizi (ANOVA) kullanıldı. Deney sonuçlarına göre, CMM ve LT için optimum kesme parametrelerinin 5 mm cidar kalınlığı, 0,05 mm/diş ilerleme miktarı ve 160 m/dk kesme hızı (A2B1C3) olarak belirlenmiştir. ANOVA sonuçlarına göre, CMM ve LT için form hataları üzerine en etkin kesme parametresi sırası ile %56,18 kesme hızı ve %68,06 ilerleme miktarı olmuştur. Ayrıca LT ölçüm sonuçları CMM ölçüm sonuçlarına göre ortalama %63 oranında daha yüksek çıktığı görülmüştür.

COMPARISON WITH THREE-DIMENSIONAL COORDINATE MEASURING AND LASER SCANNING OF EFFECT OF FORM ERROR OF CUTTING PARAMETERS IN MILLING FREEFORM THIN-WALLED AA 5083-H111 ALLOY
Abstract
This article focuses on the comparison of three-dimensional coordinate measuring (CMM) and laser scanning (LS) results of the effect of cutting parameters on form error in the milling of free-form thin-walled AA 5083-H111 alloy. The experiments were carried out in a CNC vertical machining center under dry machining conditions by using uncoated carbide cutting tool according to the experimental design prepared using the Taguchi L32 orthogonal array. Analysis of variance (ANOVA) was used to determine the most important cutting parameters affecting form errors for CMM and LT. According to the test results, optimum cutting parameters for CMM and LT were determined as 5 mm wall thickness, 0.05 mm/tooth feed rate and 160 m/min cutting speed (A2B1C3). According to the ANOVA results, the most effective cutting parameters on form errors for CMM and LT were 56.18% cutting speed and 68.06% feed rate, respectively. In addition, it was observed that the LT measurement results were 63% higher on average than the CMM measurement results.
