DMLS Eklemeli İmalatta Süreç Ve Maliyet Modeli Geliştirilmesi

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.

Anahtar Kelimeler:

DMLS, eklemeli imalat, lazer toz yatak, imalat süresi, imalat maliyeti

DMLS Additive Manufacturing Process and Cost Model Development

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.

Keywords:
