Sayısal denetimli hidrolik pozisyonlama sisteminin Taguchi metodu ile optimizasyonu

Bu çalışma, CNC takım tezgâhların denetiminde kullanılan FM 357 fonksiyon modülü ile kontrol edilen hidrolik sistemin pozisyonlama doğruluğunu incelemektedir. Sistem oransal yön denetim valflerinin yönlendirdiği iki adet silindirin sürdüğü iki eksenden oluşmaktadır. İlerleme oranı, hareket mesafesi, yön ve atalet yükü parametrelerinin pozisyonlama doğruluğu üzerindeki etkileri ve bunlara ait optimum seviyelerin tespiti Taguchi metodu ile gerçekleştirilmiştir. Buna göre minimum pozisyonlama hatası 10 mm/dk’lık ilerleme oranında, 5 mm’lik hareket mesafesinde,“-” yönde ve 5 kg’lık atalet yükünde elde edilmiştir. Son olarak, yapılan doğrulama deneyleri, Taguchi metodunun, sistemin optimizasyonunu yeterli doğrulukta gerçekleştirdiğini göstermektedir.

Optimization of numerical controlled hydraulic driven positioning system via Taguchi method

This study, investigates the positioning accuracy of the hydraulic system that is controlled by FM-357 function module used in the control of CNC machine tools. The system consists of two axes driven by two cylinders directed by proportional directional valves. The effects of feed rate, motion distance, direction and inertia load on the positioning accuracy and the determination of their optimum levels are achieved via Taguchi method. According to this, minimum positioning error is obtained in the motion distance of 5mm, in “-” direction and at the inertia load of 5kg. Lastly, the confirmation experiments showed that Taguchi method achieves the optimization of the system with sufficient accuracy.
