Diseño y construcción de un prototipo de cortadora laser CNC para el grabado y corte de madera (MDF) de un espesor 4mm para la empresa Servihardmetal

Abstract

One of the focuses of the Mechanical Engineering career is to automate production centers through machines that carry out work using software, obtaining results that cannot be obtained by human hands in the cutting of materials, in this project the realization was proposed of a prototype that engraves and cuts MDF wood using a laser. Given the importance of carrying out high precision work for small and medium-sized companies that carry out manufacturing processes in order to satisfy customer demands, machines have been made that work autonomously through the control of a computer. In this project the design, materials and operation of the prototype are described, the purpose of this machine is taken into account, which is the engraving and cutting of wood, for the correct implementation of each mechanical and electronic element. The prototype was designed to engrave MDF wood as the main material and cut it with a thickness of 4mm using a 15W laser. With the laser cutter running, tests were performed with different factors, such as focus, travel speed and power, to obtain results with the best working times. Finally, conclusions and recommendations reached in the development of the thesis project are presented.
