Control numérico computarizado aplicado a la automatización de una cortadora a plasma.

Abstract

This project aimed to design and implement a plasma cutting machine with computerized numerical control that would allow to improve the speed, precision and saving of material of the company in which it will be implemented. In addition, it is manufacturing cost is lower than the retail price of these equipment and reduces the occupational risks that this tool represents before it is manual use. The implementation of this project was based on the deductive method and to facilitate it is understanding it was divided into three significant part: Mechanics, electronics and software. The mechanical part dealt with the design of the movement shafts and the cutting table, was built in carbon steel. The electronic part works through the connection of a computer to a control card in charge of processing the commands of G code and by means of controllers, operate stepper motors. In addition, the use of three software was established: AutoCAD, for the design of images, LazyCam, in charge of the conversion of the files of AutoCAD to G code and Match 3, which is the main software, represents the interface and is connected to the controller card. As final results, we obtained: 86.08% in cut precision, 89.81% in cutting speed, and a raw material waste of 0%. This fulfills the expectations of the company and obtains a versatile equipment since with just changing the tool, you can get another type of equipment like laser cutter or milling machine. Staff training on the use of machinery is recommended.
