    Many research studies may be found regarding the measurement of surface roughness parameters. Most of them are focused on amplitude parameters as they are the most commonly used in industry, while little research has been found on the spacing ones. Spacing roughness parameters measure the horizontal characteristics of the surface deviations. In this present study, the influence of current intensity, pulse time and duty cycle on spacing roughness parameters Sm and Pc has been analyzed. Design of experiments techniques are used in order to both model and predict the most influential factors by using a small number of experiments. Current intensity of 2 A, pulse time of 25 mu s and duty cycle of 0.5 are selected as the best machining conditions in order to obtain the lowest surface roughness.

    Spacing roughness parameters analysis on the EDM of TiB2
    (Elsevier, 2017) Torres Salcedo, Alexia; Luis Pérez, Carmelo Javier; Puertas Arbizu, Ignacio; Ingeniería Mecánica, Energética y de Materiales; Mekanika, Energetika eta Materialen Ingeniaritza
    Titanium diboride (TiB2) is a novel sintered ceramic material which has attracted a great deal of interest because of its excellent mechanical properties, wear resistance and chemical resistance. At present, this ceramic is used in specialized applications in such areas as impact resistant armor, cutting tools, crucibles and wear resistant coatings. In this present research work, effects of current intensity, pulse time and duty cycle on the spacing roughness parameters Sm and Pc have been studied. In addition, statistical tools based on the design of experiments as well as multiple linear regression techniques have been used. Experimental results suggest that the optimal conditions to obtain a minimum Sm of 52.60 gm and a maximum Pc of 190.60 cm(-1) were: 2 A, 5 mu s and 0.4, respectively, for current intensity, pulse time and duty cycle.
