Implementação de comando numérico computadorizado em uma mesa de coordenadas

Abstract

The automation of machine tool mechanical components using Computer Numerical Control is an often subject in the machining business. However, even if one have a general notion of the necessary for this attempt, it is not easy to find a project showing clearly the practical step-by-step of the basic operations for doing so. This work has the intent to present, to the interested reader in the theme, what is need to turn a machine tool worktable with hand crank control into a machine tool worktable controlled by CNC, employing as interface the commercial software Mach3, reporting the whole planning and execution of what is propose since the phase of project until the phase of stepping motor’s electronic configuration, in addition to make explicit all the bare mechanical and electronic components to this work. Therefor the section that explains the materials and performed proceedings was splitted in five parts for better knowledge of the reader. In the first one is proposed the linkage of the stepping motors rotor to the worktable axis, in the second part is explained the planning and fabrication of the metallic supports that fix the stepping motors to the worktable, in the third one is exposed the electronic components required, in the penultimate part is described the Mach3 configuration and finally, in the fifth and last part, are shown the mechatronic components utilized for this specific case. The result achieved was a machine tool worktable with both axis automatized by stepping motors, been now completely commanded by CNC.
