Construcción de un sistema CNC para el corte y grabado de placas PCB.

Abstract

In these times there are automated CNC Computerized Numerical Control machines that replace human intervention for their elaboration, both in machining, engraving on solid surfaces, among others. Such equipment is robust and its construction for cutting and engraving PCB Printed Circuit Board which that replacing the traditional procedures for the elaboration in electronic equipment obtaining results that are more perfect as precise in the routing of the tracks by means of numerical control machines decreasing the manufacturing time, thus achieving considerable effects to the construction in this artifice both positively in time and an aid in nature so that in comparison to the printed process of tracks for electronic circuits, ironing and burning by means of application in the use of acids, which in turn, those who handle incorrectly have direct effects on the skin and sight, therefore, once finished by the process of treatment in chemical solution with the use of acids these pollutants become an affectation to the nature of the marine biome. The interconnection that it has both for the control in the stepper motors and the milling machine that are controlled by a CNC Shield V3 module through the GRBL library of Arduino IDE and application of calculations for the speed of movement as the positioning of the tool to proceed with the proper operation of the equipment on solid surfaces such as bakelite, thus replacing the traditional method avoiding accidents and pollutants.
