In this work, an attempt has been made to design and fabricate a new type of dynamometer to measure radial component of cutting force using strain gauges. Dynamometer is required to measure the components of cutting force in any metal cutting process. The dynamometer has been calibrated and tested for performance. It is used in roller burnishing experiment on aluminum work piece under various conditions. In roller burnishing, a hard roller is pressed against a rotating cylindrical work piece and parallel to the axis of the work piece on lathe. Optimum values of burnishing force and the corresponding surface roughness value (Ra) are obtained for different lubricant applications in roller burnishing operation. This dynamometer can be manufactured at a low cost and it can be used for tests on lathe in metal cutting laboratories and engineering colleges.
Keywords: Dynamometer, strain gauges, roller burnishing, surface roughness value Ra, burnishing force.
