Comparative analysis of wobble milling, helical milling and conventional drilling of CFRPs [PDF]
The International Journal of Advanced Manufacturing Technology, 2020 AbstractDue to its excellent specific mechanical properties, carbon fibre-reinforced polymer (CFRP) composite is a widely used structural material in the aerospace industry. However, this material is difficult to cut, mainly due to its inhomogeneity and anisotropic features and because of the strong wear effects of its carbon fibres.

Mechanics and Dynamics of Helical Milling Operations
Strojniški vestnik – Journal of Mechanical Engineering, 2014 This paper presents analytical models dealing with time domain cutting forces and the time and frequency domain dynamics of helical milling operations. The cutting forces both on the side-cutting edges and on the end-cutting edges along the helical feed path are modelled by considering the tangential and the axial motions of the tool.
