So that you can make processes leaner in order to reduce costs of production, shortening the delivery time and increasing the quality of the final product in any industrial branch is extremely important to clearly define the ideal parameters of production processes. When comparing the high cost of your raw material with other steels traditionally used in the industry, it is clear that having a process assertive in making cutting tools, bending, injection molds and their components is essential, thus enabling the necessary investments in processes and equipment involved in manufacturing. To achieve the best combination of the parameters, a statistical experimental design was used for analysis of effect of the voltage, current, ON time and OFF time parameters on the results of material removal rate (MRT) and roughness over a material widely used in the manufacture of injection molds, the AISI P20 steel, which gathers highly desirable characteristics for the process. Through this research it was possible gain an understanding of the possible combinations between parameters that resulted in a balance between machining time and an admissible roughness for the fabrication of matrices, the superiority of the current parameter over the results obtained.
