Abstract:

Electro erosion is a manufacturing process designed for machining difficult-to-process materials. This paper presents the fabrication of a miniature punching die used for perforation and cutting, made from X15 steel, using electro erosion. Due to its properties, such as high hardness, complexity, and the need for protection against surface layer damage, this material cannot be processed with conventional methods. The electro erosion process ensures high quality and dimensional precision in the finished product. A digital surface roughness meter and the functional schematic of the PGI system are also discussed. Various roughness measurement techniques are presented, along with graphical representations and the bearing area curve. The paper highlights variations in parameters at four measurement points, as well as changes in the "c" coefficient. Finally, the surface roughness parameters Ra, Rq, and Rz are analyzed.
