Even today tables are used in the calculation of structures formed by flat elements, these methods are acceptable only for a limited number of cases, but even so, in some situations, tables are used. With time some methods of differential equations resolutions were emerging and accepted as the most effective solution. Today, with the advancement in technology, there are already some programs able to solve more complex problems in less time using these methods. Aiming to optimize time and better understand the physical behavior of plates, this work presents the theory of plate, the Boundary Element Method (BEM) applied to solve problems of plates (slabs) with various boundary conditions and load through the program Placas2 (TAGUTI, Y.-2010) in Fortran language

This paper presents a study on the development of a manufacturing system of printed circuit boards through copper milling. An advantage of this system is the replacement of chemical processes by physical process presenting a sustainable solution. The paper uses programs that will generate G-code needed to establish the coordinates where the milling forms the tracks. After obtaining the code, it will be transformed into steps that will be sent through the serial port to the microcontroller and the serial communication control will be in software. After obtaining information the microcontroller will execute the movement of the stepper motors through their drivers, H-bridge, the microcontroller also drives the spindle motor responsible for rotating the grinding tool, using a driver with a optocoupler and TRIAC
