Abstract

Bu çalışmada son yıllarda gelişim göstererek endüstrinin temel imalat
metotlarından biri haline gelen eklemeli imalat üzerine, imalat süresi,
süreçleri ve maliyetler ekseninde çeşitli analizler gerçekleştirilmiştir. Toz
yatak birleştirme teknolojilerinden bir tanesi olan “Doğrudan metal lazer
sinterleme” (DMLS) metodunun işlem süreleri ve süreç analizinin yapılması
sonucunda literatürde yer alan mevcut denklemler ve ilave olarak imalatın tüm
adımlarını ve her türlü gideri hesaplamaya dâhil ederek genel bir maliyet ve
süreç hesaplaması denklemi türetilmiştir. Elde edilen denklem Türkiye örneklemi
üzerinden kontrol edilmiş ve Türkiye şartlarına yönelik bir çalışma yapılmıştır.
Geliştirilen model ile imal edilmesi planlanan parçaların DMLS ile eklemeli
imalat süreleri, imalat verimliliği ve etkin tezgâh kullanımı hakkındaki
verilere ulaşabilmek mümkün hale gelmiştir. Bunların yanında imalat tezgâhların
amortisman hesapları ve başa baş noktası analizleri farklı işletme şartlarında
incelenerek gerçekleştirilmiştir.

DMLS Additive Manufacturing Process and Cost Model Development

Abstract

In this study, various analyzes have been carried out in terms of
manufacturing time, processes and costs on the additive manufacturing, which
has become one of the basic manufacturing methods of the industry. As a result
of the processing times and process analysis of the "direct metal laser
sintering" (DMLS) method, one of the powder bed fusion technologies, a
general cost and process calculation equation has been derived, including the
existing equations in the literature, plus all steps of manufacturing and all
sorts of calculations . The resulting equation was checked on the sampling
Turkey and a study was carried out for the conditions of Turkey. With the
developed model, it is made possible to reach the data about the manufacturing
time, manufacturing efficiency and effective use of the machine with DMLS parts
planned to be manufactured. In addition, amortization calculations and
head-to-head analyzes of manufacturing machines were carried out under
different operating conditions.
