| Abstract: | This paper measures the roughness of non-conventionally machined components. The data ob-tained are inputted into computer and the amplitnde density function autocorrelation function and powerspectral density function of each component are found out separately by means of mathematical statisticmethed and their graphs are plotted. These functions and graphs are anal ysed comprehensively to evaluatethe topography of non-conventionally machined surface. |
