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.

摘要

重新组合的人造板在制造过程中使用石油来源的聚合物和甲醛等物质. 替代这些面板的一个解决方案是使用可再生和可生物降解原材料的天然纤维增强复合材料. 为了使用这些复合材料，有必要研究它们的可加工性. 本文旨在通过测量香蕉茎纤维和蓖麻油聚氨酯复合材料的表面粗糙度、切削力和评价加工过程中产生的表面缺陷来分析香蕉茎纤维和聚氨酯复合材料的端铣加工. 切削速度和切削力是影响端铣加工质量的主要因素.
