The increasing number of works related to the surface texture characterization based on 3D information, makes convenient rethinking traditional methods based on two-dimensional measurements from profiles. This work compares results between measurements obtained using two and three-dimensional methods. It uses three kinds of data sources: reference surfaces, randomly generated surfaces and measured...
The arithmetical average roughness, Ra, is widely used to evaluate the quality of surface finish in machining parts. Its value depends on cutting parameters: cutting speed, feed and cutting depth. It is necessary to optimize the value of these parameters to achieve the desired quality, especially in the absence of cutting fluids. In this work, a study of the superficial quality of test bars, turned...
