Sistema de movimentação por pinhão e cremalheira para router CNC de grande deslocamento e baixo custo, voltado ao corte de madeira

Abstract

CNC routers can be destined for many materials machining, mainly non-ferrous. Machines available in the market are high-priced due to its components technology and precision. Little information is available about solutions for large displacement and low cost. In this work, a linear motion system based on pinion and rack for a low cost and large displacement CNC router was designed. The project requirements were based on costumers who prioritize low cost over productivity and precision, such as hobbyists and MDF objects craftsman. A prototype was build and the meeting to the established requisites was validated.
