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.
