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

The process of burnishing is performed by applying a highly polished and hardened ball or roller with external force onto the surface of a cylindrical work piece. The burnishing process increases the surface hardness of the work piece, which in turn improves wear resistance, increases corrosion resistance, improves tensile strength, maintains dimensional stability and improves the fatigue strength by inducing residual compressive stresses in the surface of the work piece. In the present experimental work, both ball and roller burnishing tools are used. Experiments are conducted to study the performance of the ball and roller burnishing tools on lathe, along with the influence of number of burnishing tool passes on the surface roughness and surface hardness of brass specimens. The results revealed that improvements in the surface finish and increase in the surface hardness are obtained by the increase of the number of burnishing tool passes in both ball burnishing and roller burnishing on the brass specimens.Keywords
