Repotenciación y automatización de una mesa de coordenadas para corte por plasma (MCCP) de tres ejes

Abstract

n a metalworking industry in the city of Cuenca has a coordinate table used for oxyfuel work that operates with a basic control of the Cartesian axes X and Y, which has no technical ability to perform high precision or good work Surface finish, for which the present project is presented whose main objective is the repowering and automation of a Coordinate Table for Plasma Cutting (MCCP) with three axes. As a result of the project, a linear displacement system was implemented in the Z axis, a torch height control system (THC) was incorporated, a laser autopositioning was incorporated to pinpoint the starting point of the work with millimetric precision and finally Integrated a software architecture based on CAD / CAM tools to automate the cutting process. For the evaluation of the implemented system a piece of dimensions 163x150mm was machined in a steel plate T21 of ¼ "of thickness, obtaining a piece with maximum variations of 0.7 mm with respect to the design, evidencing the good performance of the system.
