Abstract
BİLGİSAYAR DESTEKLİ PROTOTİP HİDROLİK PRES İLE ÇÖKERTME İŞLEMİNDE PRESİN BASINÇ, HIZ ve POZİSYON KONTROLÜNÜN İNCELENMESİ Bu çalışmada, bir prototip hidrolik presin basınç, hız ve pozisyon kontrolünün, örnek bir Alüminyum sac çökertme deney düzeneğinde, çökertme derinliği üzerindeki etkileri araştırılmıştır. Bilgisayar kontrollü bir prototip hidrolik presin basıncı, hızı ve pozisyonu değiştirilebilir bir kontrol sistemi kurulmuştur. Taguchi metoduna uygun 9 deney yapılmıştır. Sonuçlar; basınç, hız ve pozisyon değerleri ile çökertme derinliği arasında doğru orantı olduğunu göstermiştir. Hız ve basınç çökertme derinliğine pozisyona göre daha çok etki etmiştir. Sonuç deneyleri yapıldıktan sonra basınç sensöründen okunan basınç değeri her parça için yaklaşık 22,55 bar’dır. Servohidrolik, Labview, 1050 Alüminyum sac, Çökertme Deneyi.
EXAMINATION OF THE CONTROL OF THE PRESSURE, VELOCİTY AND POSITION OF A PRESS IN A FORMING PROCESS WITH A COMPUTER AIDED PROTOTYPE HYDRAULIC PRESS In this study, the effects of the pressure, velocity and position control of a computer aided prototype hydraulic press on the depth of erichsen were investigated in an example of 1050 Aliminium sheet erichsen test. The Control System, which the pressure, velociy and position of a computer aided prototype hydraulic press are changed, was established. 9 experiments were done conveniently to Taguchi method. Results showed that pressure, velocity and position are in a positive function of the depth of 1050 Al sheet tested. The depth was influenced by more pressure and velocity than position. After the responded tests were applied, avarage of the pressure, which was measured by pressure sensor, was 22,55 bar and for all workpieces.
