In this study, the effects of the feed rate parameter in the milling process were investigated. For this purpose, Al7075 material was milled with feed rates of 0.1, 0.15, 0.2, 0.25 and 0.3 mm/rev, keeping other machining parameters constant. Milling was done along the part for each feed value. Vibration was measured with the connected device on the workpiece during milling. Vibration values were evaluated statistically and the effect of progress on vibration was discussed. According to the data obtained from the vibration measurement, in general, the increase in the feed at constant speed reduced the vibration. With the decrease in the cutting ability of the tool, the standard deviation of the data increased and a more irregular vibration pattern was detected. The results obtained will support the processes of determining the optimum feed value in milling.

Bu çalışmada, frezeleme işleminde ilerleme hızı parametresinin etkileri araştırılmıştır. Bu amaçla Al7075 malzemesi diğer işleme parametreleri sabit tutularak 0.1, 0.15, 0.2, 0.25 ve 0.3 mm/dev ilerleme hızları ile frezelenmiştir. Her bir ilerleme değeri için parça boyunca kanal frezeleme yapılmıştır. Frezeleme sırasında iş parçasında bağlı cihaz ile titreşim ölçülmüştür. Titreşim değerleri istatistiksel olarak değerlendirilmiş ve ilerlemenin titreşime etkisi tartışılmıştır. Titreşim ölçümünden elde edilen verilere göre genel olarak, sabit devirde ilerlemenin artışı titreşimi azaltmıştır. Takımın kesme kabiliyetinin azalması ile verilerin standart sapması artmış ve daha düzensiz bir titreşim seyri tespit edilmiştir. Elde edilen sonuçlar frezelemede optimum ilerleme değeri belirleme çalışmalarına destek olacak niteliktedir.
