Özet:

 

D rilling is a widely used machining method in engineering applications, playing a major part in machining operations. Chip morphology is an indicator, which shows the quality of machining. Especially, chip thickness ratio is a characteristic to show the level of deformation and cutting effects during machining operations. In the present paper, the influences of parameters such as feed rate, spindle speed, point angle, and fluctuation size on the chip morphology investigated. The most influential parameter on the chip thickness was feed rate, while point angle on the chip width. The most favourable chip thickness ratio values and a lower fluctuation size in thrust force were achieved at 100o and 118o point angles. Although the higher fluctuation in thrust force and chip thickness ratio values were observed at 136o and 154o point angles, the most favourable chip morphology was obtained at these point angles. In other words, the higher point angles were found to be advantages in drilling operations to obtain a better chip morphology and chip geometrical dimensions.
