In this work, an
algorithm is developed to prevent time losses that occur during the calculation
of Root Mean Square (RMS) of the vibration signals. Vibration signals are
obtained during cutting of super alloy material Inconel 718 on a CNC lathe
machine with a cutting speed of 50 meters per minute, 0.15 mm progress per
revolution and 2.5 mm cutting depth. The data is loaded to the computer via the
vibration sensor (353B31 from PCB Piezotronic) and the digital-analog converter
card (DAQ 6062E) and then mathematical expressions are created in Matlab
environment. RMS is one of the most important evaluation parameters in the
evaluation of this data. Running the classical algorithm, it is observed that
there was excessive time loss in the RMS calculation of total 120 million data about
60 tests, each test lasted about eight hours. So a new algorithm has been developed
that can do operations much faster. The results of the new algorithm are
compared with the results of the classic algorithm and it is determined that
the new algorithm produces 100% correct results. 99% of the time loss is
avoided with this new algorithm.

Bu çalışmada; titreşim sinyallerinin kare ortalamalarının karekökü
(RMS) hesaplanması sırasında meydana gelen zaman kayıplarının önüne geçilmesine
yönelik bir algoritma geliştirilmiştir. Titreşim sinyal verisi; Inconel 718
adlı süper alaşım malzemenin, CNC Torna tezgâhında; 50 metre/dak kesme hızı, 0,15 mm/devir ilerleme hızı, 2,5 mm kesme derinliğindeki
kesimi sırasında elde edilmiştir. Veriler titreşim sensörü (PCB Piezotronic’e
ait 353B31) ve dijital-analog çevirici(DAQ 6062E) kartı ile bilgisayara alınmış
ve Matlab ortamında matematiksel ifadeler oluşturulmuştur. RMS ise bu verilerin
değerlendirilmesinde önemli değerlendirme parametrelerden bir tanesidir. Klasik algoritmada, yaklaşık 60
testlik toplam 120 milyon verinin işlendiği
RMS hesaplamasında aşırı zaman kaybı olduğu gözlemlenmiş; her bir test yaklaşık
sekiz saat sürmüştür. Bundan dolayı işlemleri çok daha hızlı yapabilen yeni bir algoritma geliştirilmiştir.
Yeni algoritma ile klasik algoritmanın sonuçları
karşılaştırılmış ve yeni
algoritmanın %100 doğru sonuçlar ürettiği tespit edilmiştir. Yeni algoritma ile zaman
kaybının %99 oranında önüne geçilmiştir.
