Projeto e construção de máquina CNC Router para prototipagem e produtos

Abstract

Motivated by the advantages of home construction of CNC Router, the development of the machine capable of making products or prototypes is quite feasible given the trend of market growth of these, so there is appreciation of existing ones and increase in the purchase price. Several companies are already opting to acquire them via design and construction, instead of obtaining them at high prices. The present work establishes the reasons and the efficient methodology to dimension, project and build the CNC Router with the adequate choice of rectified axes, trapezoidal spindles, stepper motors and spindle. It was established necessary steps for the effectiveness of the project, first the CAD design secured with finite element simulation is the starting point of reliability. In experiments and results, validation was addressed to ensure accuracy and possible failures during operation, ensuring reduced budget using free electronics platforms.
