Robô cartesiano cnc: projeto e construção de um robô cartesiano multifuncional

Abstract

Cartesian robots are a group of robotics where CNC machines are inserted. They in their turn, are specific and well defined movement automatic machines, controlled by computer numerical control. They are applied in specific jobs, mostly to manufacture mechanical parts, being able to milling, cutting, 3D printing, among others, presenting characteristics of good repeatability, precision and reliability. This monograph presents the design of a cartesian movement CNC machine, aimed at multifunctionality, being versatile enough to work with more than one type of mechanical manufacturing method. It will be covered the main systems which make up these machines, such as existing solutions for movement, traction, control, structure, instrumentation, software and firmware. It will be also discussed a bit of each alternative’s advantages, disadvantages and costs, followed by the selection of the ideal components for the project. The final prototype will be built and presented in this document, bringing the main conclusions from the experiment. Finally, the results obtained with the built machine will be presented and criticized.
