Projeto de torno CNC para prototipagem rápida e outros usos

Abstract

This work seeks, through the design of a low-cost and local fabrication CNC lathe, to align itself with the global effort to expand the realization of projects for the development of technologies free for use, distribution and modification. This machine is capable of cutting parts in materials of low mechanical resistance, such as medium density fiberboard (m.d.f.), styrofoam and polyurethane, so that it can be used, among other uses, to facilitate the work of design offices. The lathe’s project involves both the modeling of its mechanical structure in CAD software SOLIDWORKS and the design of its electrical and electronic connection scheme. The automation and control can be performed by any desktop computer, using its parallel port as communication interface, which significantly reduces the total cost of construction of the lathe, as well as simplify the process of maintenance and use of themachine. The other components used are mostly made of wood and other civil construction materials, so that almost all of the equipment can be manufactured locally
