Abstract Lots of efforts have been dedicated to vibration monitoring and suppression on the complex system joined by tool-machine, tooling, workpiece and clamping devices in machining processes, specially referring to the mechanisms that lead to wear and damage of the tool. However, the effects of those vibrations over the surface integrity of the parts that are being manufactured in these conditions in not well known. In this research project, a stability characterization of this kind of system during hard turning of two hot work tool steels is proposed, considering that lathe spindle speed and depth of cut were chosen as the input variables. Tests will be monitored using accelerometer and an Arduíno low cost acquisition system. After that, the surfaces of the machined specimens will be evaluated in terms of roughness, as well as the sub-superficial layers will be analyzed by X-ray diffraction in order to infer residual stresses. | |
