Construção e análise de um equipamento de usinagem CNC de bancada a baixo custo

Abstract

The constant search for technologies to automate machining processes is driven by the demand for quality products and speed. With the industrial evolution, the evolution of computers came along with it, which enabled the development of software capable of designing parts and controlling machines for process automation. This work consists in the construction of a low cost bench CNC (Computer Numerical Control) milling machine, using open source software and hardware. The equipment is capable of executing movements in the Cartesian coordinates (X, Y, Z) through mobile bases that are activated by stepper motors controlled by the Universal Gcode Sender program, which allows the import and creation of G code. After its construction and operating tests, their accuracy were verified, through metrological analysis of the equipment and of a machined part, with the results, the type of application of the machined part was defined, in accordance with the regulations of the German standardization institute (DIN - 68100), for heat treated wood tolerances (HT - Heat Treatment).
