Materials Processing and Experimental Characterisation Materials Processing Commercial PLA (PLI 005 grade, Natureplast) served as the matrix material, compounded with short hemp fibers (average length 160 μm, obtained through hammer milling and defibration) at 20 wt% loading and polyethylene glycol plasticizer at 5 wt% respectively PEG 1500 and PEG 20000.
Strongly aligned materials or multiaxial forming paths will require an explicit orthotropic extension of the elastic stiffness and possibly of the viscoplastic flow rule.

Despites cutting parameters influence in turning processes are practically well understood, the development of new materials and cutting tools demands a constant review on its role on process performance.
Cutting Parameters and Surface Finish Taking into consideration the material removal rate and machined surface, the values adopted for the cutting parameters can be large or small, depending on demand and availability of materials and tools.
In roughing operations there is not much concern with the surface finish, since the goal is a high rate of material removal over a certain tool life.
