The aim of this paper is the machinability analysis, in different drilling conditions, of sintered metals filled with a machinability enhancer. The cutting parameters involved in the study are: rotating velocity, feed rate and coating of the tool. To reduce the number of experimental tests required, a 2^(k-1) fractional design of experiment with three two-level factors and two replications for each run was employed. The experimental design was repeated for three sintered metals with different hardness or density. The obtained results show new insight into the machining mechanism of sintered material and into the influence of the cutting parameters on the machining forces.

Abstract
The aim of this paper is the machinability analysis, in different drilling conditions, of sintered metals filled with a machinability enhancer. The cutting parameters involved in the study are: rotating velocity, feed rate and coating of the tool. To reduce the number of experimental tests required, a 2^(k-1) fractional design of experiment with three two-level factors and two replications for each run was employed. The experimental design was repeated for three sintered metals with different hardness or density. The obtained results show new insight into the machining mechanism of sintered material and into the influence of the cutting parameters on the machining forces.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
