Desenvolvimento de Máquina CNC para Fabricação de Encostos Anatômicos e Personalizados: Usinagem em Blocos de Espuma Flexível de Poliuretano

Abstract

This article outlines the development of a Computer Numerical Control (CNC) machine, designed primarily for machining flexible foam blocks to manufacture anatomically customized backrests, primarily targeting individuals with Cerebral Palsy (CP) who require stabilization and postural adjustment. In this context, the customization of Assistive Technologies is a crucial factor directly impacting the lives of people with disabilities (PwD), leading to long waiting queues and limited availability from specialized centers such as the Lucy Montoro Rehabilitation Network, AACD, and the SARAH Network. Therefore, the developed CNC machine aims to reduce the manufacturing time for backrests while incorporating open-source software and hardware, resulting in a significant reduction in construction costs. In the conducted tests, the CNC machine demonstrated effectiveness in machining flexible foam blocks with an accuracy close to the predicted. Subsequently, the plan is to execute the manufacturing process of a personalized anatomical backrest based on a real model obtained through 3D digitization. The expectation is that this tangible advancement will result in significant improvements in the quality of life of PwD, particularly for individuals with Cerebral Palsy.
