First of all, with Taguchi method, machining parameters that will be effective in the bonding strength as well as their interactions on each other were determined in the test. Then, multiple level experiments were conducted to determine how the effective parameters varied over a wide area. Slopes of the curves obtained in these tests were studied, and then, final tests were conducted to obtain the best bonding strength possible. In this way, machining parameters that would offer the highest bonding strength of the titanium-porcelain matrix in a stepwise adjustable EDM machine were obtained. By taking into consideration the steps on the EDM machine where the tests were conducted, it is seen that, when a full factorial experiment is undertaken, 5 power x 2 polarity x 2 type of dielectric x 2 sandblasting or non-sandblasting x 2 kind of electrode x 10 pulse-on time, it necessitates 800 different tests to be executed, but, with the applied method, 16 + 18 + 3 yields 37 different tests where the results that include all possible alternatives were obtained. As a result, EDM machining parameters that offer the highest adhesion and are relatively higher, 31.5 N/mm(2), than the acceptable minimum value of 25 N/mm(2) were specified.en10.1007/s00170-009-1937-7info:eu-repo/semantics/closedAccessTitaniumTitanium-porcelain adhesionTaguchi methodElectrical discharge machiningEDMArticle4501.02.20205561Q1WOS:000270450100007Q2
