End Milling of Banana Stem Fiber and Polyurethane Derived from Castor Oil Composite

Abstract

Reconstituted wood panels use polymers of petroleum origin and substances such as formaldehyde in their manufacturing. One solution for replacing these panels is the natural fiber-reinforced composites that use renewable and biodegradable raw materials. In order to use these composites, it is necessary to investigate their machinability. The aim of this work is to analyze the end milling of banana stem fiber and polyurethane derived from castor oil composite by measuring surface roughness, cutting forces and evaluating the surface defects generated during the process. The cutting speed and the forces involved are the factors that most influence the quality of end milling.
