Projeto, construção e caracterização de uma fresadora CNC de bancada

Abstract

The bench CNC milling machine can be used to make parts, project models and can be used as a basis for the teaching of computerized manufacturing programming. Nowadays it is possible to control these equipments by means of embedded systems of easy access, among which we can mention Arduino. In this work the design and construction of a CNC bench milling machine capable of interpreting the standard language of numerical G-Code commands is proposed. The methodology of the project is based on a literature review on the milling process and on a market on the manufacturers’ websites seeking information on similar machines. Afterwards, it is presented the design of the equipment, the selection of components, manufacturing methods used and tests for characterization of the machine. The conception of the equipment was designed aiming the use of accessible materials and manufacturing methods. In this way it was possible to construct the miller, which is functional, being tested in the cutting of MDF sheets. The machine has an average relative error between the tests performed of 0, 77 %.
