Cutter systems and other motion systems designed by taking advantage of the crank-connecting rod mechanisms find a wide range of uses. In order to increase the cutting performance of the CNC cutting machine, which is designed to cut multi-ply textile products, it is necessary to increase the speed. However, the increase in speed brings along dynamic balancing problems in rotating mechanisms. In this study, a mechanism that can cut at speeds of 6000 rpm was designed and modeled in CAD program, balancing work for reducing shaking forces was made and analyzed in engineering simulation program. The results show that the balancing weight reduces the shaking forces in critical bearings.

CNC KESİM MAKİNESİ ANA HAREKET SİSTEMİNİN SARSMA KUVVETLERİNİN AZALTILMASI VE BAĞLANTI ÇUBUĞUNUN YAPISAL ANALİZİ

Öz

Krank-biyel mekanizmalarının avantajlarından faydalanılarak tasarlanan kesici sistemler ve diğer hareket sistemleri geniş bir yelpazede kullanım alanı bulmaktadır. Çok katlı serilen tekstil ürünlerini kesmek üzere tasarlanan CNC kesim makinesinin kesim performansının istenen seviyeye gelmesi için hızın artırılması gereklidir. Ancak hızın artması dönen mekanizmalarda dinamik dengeleme problemlerini de beraberinde getirir. Bu çalışmada 6000 d/dk. hızlarda kesim yapabilecek bir mekanizma CAD programında tasarlanıp modellenmiş; sarsma kuvvetlerinin azaltılmasına yönelik dengeleme çalışması da analiz programında test edilmiştir. Dengeleme ağırlığının, kritik rulmanlardaki sarsma kuvvetlerini düşürdüğü sonucu elde edilmiştir.
