The determination of the influence of the machining parameters on the amount of removed rust on the steel surface is important in the selection of these parameters to increase the machining productivity. In this study, we conducted tests to determine the influence of machining parameters on the amount of removed rust on the steel surface. Tests were performed according to Box-Behnken matrix in two cases: Acids are used or not used in cleaning solutions. In the absence of the use of acids, the selected parameters were the input parameters of the test including machine power, cleaning time and the distance from the steel surface to the ultrasonic head (referred to as the machining distance). Four parameters have been selected as the input parameters when using acids in the detergent solution, including machine power, machining distance, solution concentration and machining time. Finally, orientation for the next research has also been proposed in this paper. Keywords : Steel Surface Cleaning, Ultrasonic Machining, Machining Productivity. I. INTRODUCTION Today in the mechanical industry, in the field of mechanization of agriculture and forestry, in the field of defense, civil, etc., cleaning equipment plays an important role. Classic cleaning methods such as using hands in combination with solutions do not guarantee the cleanliness of the parts to be cleaned, the working environment is too toxic, people are always in direct contact with chemicals, so their health is not guaranteed. Especially for details with complex structures with high impurity adhesion, this cleaning method is difficult to guarantee. For the electrolytic cleaning method, the energy consumption is quite large, so the surface of the parts will not remain intact when the cleaning time is long [1].
