AB  - Hole making is one of the most common machining operations in fibrous composites. Holes can be
produced using conventional machining technologies. However, in these cases, the size of
delamination and burr appearance are often significant mostly due to the relatively large axial cutting
forces. The main purpose of this research paper is to optimise and compare tilted helical milling
processes in the case of carbon and glass fibre reinforced polymer (CFRP and GFRP) composites. In
the scope of this research paper, numerous tilted helical milling experiments were carried out on CFRP
and GFRP composites using an uncoated carbide end mill. The influences of the tilting angle and the
pitch of the helical tool path on the axial cutting force were analysed and discussed based on
experimental results and analytical models. In addition, machining-induced burr and microstructure
were analysed using optical-digital and scanning electron microscopy, respectively. Experimental
results show that both cutting force and burr are significantly influenced by pitch and tilting angle.
Furthermore, the maximisation of the tilting angle is recommended in any of the cases examined in the
scope of our study.
