Effects of different WAAM current deposition modes on the mechanical properties of AISI H13 tool steel.

In this work, AISI H13 tool steel build-ups were produced through wire arc additive manufacturing (WAAM). The cold metal transfer (CMT), low spatter control (LSC) and pulsed synergic (PS) current deposition modes were compared. Similar deposition strategy was employed in order to attempt to evaluate the influence of energy input on geometrical and mechanical properties of the deposits.

Specific Cutting Forces of Isotropic and Orthotropic Engineered Wood Products by Round Shape Machining.

The set-up of machining parameters for non-ferric materials such as wood and wood-based materials is not yet defined on a scientific basis. In this paper, a new rapid experimental method to assess the specific cutting coefficients when routing isotropic and orthotropic wood-based materials is presented. The method consists of routing, with different depths of cut, a given material previously machined to a round shape after having it fixed on a dynamometric platform able to measure the cutting forces.
