Diseño y construcción de un dispositivo para medir fuerzas ortogonales en el torneado de aceros de media aleación utilizando galgas extensiométricas

Abstract

The project designed and built a strain gauge-based device to measure orthogonal forces during the turning of medium alloy steels with the objective of being used in the technical manufacturing sector. The components work together as a system to obtain orthogonal forces during the milling process of 1045 steel. A steel support was designed for the mechanical component. For the electronic and control part, the ones available in the Ecuadorian market are used, such as the insert to scrape material and the uniaxial strain gauges to determine the compression. For the control part, a code is implemented through the Arduino where the readings obtained are transformed from analog signals to digital signals, by using components such as Wheatstone bridge, a DC/DC converter, a HX711 module and an AM120 converter, the comparison between the theoretical values and real values obtained was also performed, thus achieving a low percentage of error in the measurements, making the piezo resistive device effective in the measurement of orthogonal forces in the CNC lathe.
