Abstract
The production of goods using planted forest raw materials, such as MDF, has been questioned by consumers and researchers due to environmental issues involved in their manufacturing process, such as the use of petroleum source polymers, the destination of the waste generated by the processes the end of the product's life. In this scenario, the aim is to develop materials that use raw materials and inputs from renewable sources and to promote the recycling of waste. A proposed solution is the composite reinforced with natural fibers, but lack knowledge about machining possibilities through existing systems, as well as the superficial results after the necessary processes that are important for commercial use. The aim of this work was to analyze the machinability of the composite of banana stem fiber agglutinated with polyurethane derived from castor oil through a CNC milling machine, evaluating surface roughness and delamination. It was found that the surface roughness showed better results with increased cutting speed and feed rates intermediates. Delamination is mainly influenced by the arrangement and geometry of the fibers used in the composite panel, having no relationship with cutting speeds and feed rate.
