GODOY R, Juan et al. MEDICIÓN DE LAS FUERZAS DE CORTE CON UN DINAMÓMETRO PIEZO ELÉCTRICO DURANTE EL TALADRADO TÉRMICO POR FLUENCIA. Rev. Fac. Ing. - Univ. Tarapacá [online]. 2003, vol.11, n.1, pp. 65-69. ISSN 0718-1337. doi: 10.4067/S0718-13372003000100009.
Through an international cooperation with the University of Kassel, Germany a research project was developed for studying the cutting forces components and momentum determination in thin Copper and Brass sheets during the Thermal Flow Drilling (TFD) processes. In the Manufacturing Processes Laboratory of the Mechanicals Emgineering Department of Universidad de Tarapacá, Arica, Chile, equipment for measuring forces and torque measurements was installed. It was connected to a data card and installed in a pc bus. With the AXACT software it was possible to develop the feed force component and momentum or torque curves. Initially, with standard mass and a torque wrench the equipment was calibrated. After this, feed force and torque measurements were made in those thin Copper and Brass sheets. As a conclusion the feed force and the torque momentum were bigger for Brass than Copper sheets of the same thickness.
