INVESTIGATION OF THE MACHINABILITY OF PA-6/NANO-CACO3 COMPOSITE

Nowadays, polymer nano-composites have attracted manufacturers' attention because of good mechanical, thermal, and physical properties. During the past decade, the requirement of the direct machining of polymer nanocomposites increases because most of the polymer nanocomposites were produced by extrusion method in simple cross section shapes and request for personalized products increases. In this study, the effect of milling parameters (spindle speed and feed per tooth) and nano-CaCO3 content on the machinability properties of PA-6/nano-CaCO3 composites was studied by means of analysis of variance. Additionally, the effect of nano-CaCO3 content on the mechanical properties of PA-6/nano-CaCO3 composites was investigated. To this end, several experiments were carried out on PA-6/nano-CaCO3 composites to attain the required data. The results reveal that the nano-CaCO3 content on PA-6 significantly decreases the cutting forces, but does not have a considerable significance on surface roughness.
