Diseño de mecanismos y simulación del control automático del sistema de posicionamiento y desplazamiento en 3 dimensiones de la herramienta en una máquina CNC

Abstract

The objective of this project is to design mechanisms and simulate the automatic control of the positioning and displacement systems in 3 dimensions of the cutting tool in a CNC machine.The research initiated with a bibliographical study of CNC machines to provide scientific support on the topic; this allowed to define the product in the part of the conceptual design and applying the concurrent design method the technical specifications of the machine were obtained. At the end of the conceptual design are presented and selected the different alternatives of solution for the proposed modules.In the mechanical design were hold the resizing of the parts that make up the machine with help of the CAD program SOLIDWORKS and through the analysis of parameters, functions and critical conditions that allowed to obtain the final dimensions of the parts of the machine. At the end of this stage were obtained drawings of assembly, subset and workshop of the parts that make up the machine.In conjunction with the mechanical design, the automatic control was designed for the PLC S7-200 by using the MicroWIN Step-7 program and its simulation in the S7-200 and PC-Simu simulator. In the end, a cost analysis is presented, and a functional prototype was carried out with the help of the Automation laboratory team of the Faculty of Engineering.
