CNC Router de baixo custo associado com confiabilidade e precisão

Abstract

Due to the lower cost of manufacturing or purchasing CNC Routers with acceptable tolerances, many companies choose to purchase them instead of outsourcing parts manufacturing. In addition, many people have chosen to start microenterprises to sell parts manufactured on CNC Routers. The present work presents the construction of a three axis CNC milling machine, using the rectified axes, trapezoidal spindles, stepper motors and Spindle. The machine tool is used to manufacture 2D, 2.5D and some 3D cases. Throughout the work, comparatives will be discussed between the parts commonly used to manufacture milling machines, associating the low cost with reliability and mechanical and electrical precision. A CNC Router with structure in metalon and aluminuim was assembled. Validation tests were also presented and the failures found until the machine was fully operational. the machine was validated with maximum errors of 0,3 mm.
