Projeto de máquina de corte com controle numérico computadorizado

Abstract

This work approaches technical, financial and operational analyses of a CNC Router Milling Machine made up of three axes (X, Y and Z), for the machining of soft materials such as woods and aluminums. The first requirement for this project is the development of a strong machine and to minimize vibration and strain effects on its structure, providing high machining quality; the second requirement is being able to machine a whole MDF sheet (2750x1800mm). The objective of this work will be the economic feasibility study, in which it is intended to have the final acquisition cost of the project accessible and lower compared to other machines on the market. The methodology that was used on this work consists on a bibliographic review about components, technical information about similar machines on the market and modeling of this project via the SolidWorks software. Subsequently, structure analyses via the HyperMesh software will be carried out, machine elements and electrical/electronic components will be selected by analytical/computational calculi and the project building will be concluded.
