Fabricação de um dinamômetro para medição de força no corte ortogonal

Abstract

This work aimed to design and manufacture a dynamometer for measuring the force components in orthogonal cutting (cutting and feed forces). The design was based on 50 kgf load cells and on the Arduino platform. It was designed a special device able to combine adequate stiffness for the machining operation and degrees of freedom for the load cells deformation. It was used the SolidWorks® version premium 2013 x64 Edition SP03 for the project design, and its manufacture was performed at the Manufacturing Laboratory at UFRN. Part of calibration was performed using standard weights from the Metrology Laboratory (UFRN). Finally, it was possible to conclude that the prototype showed satisfactory performance and it can be used for future developments at the Manufacturing Laboratory.
