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.

Helical Feed Milling with MQL for Boring of Aluminum Alloy
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2008 MQL is applied to the helical feed milling hole-making process of aluminum alloy. It is difficult to drill on aluminum alloy without cutting fluid because the adhesion to the tool leads to a chip jam, the tool breakage or low accuracy.

Surface texture produced by peripheral milling with helical end mills
, 1972 An investigation of the surface texture produced by peripheral milling with end mills has been made. Theoretical relationships are presented to predict the theoretical cusp height and approximate the arithmetical average surface roughness based on the geometrical considerations of a circular tooth path.

Surface location error for helical mills [PDF]
, 2006 Stability and surface location error are investigated numerically for milling operations with a helical tool. A detailed mechanical model is derived that includes both surface regeneration and the helical teeth of the tool. The governing delay-differential equation is analyzed by a modified version of the semi-discretization method.
