In this way, it is possible to create even thin-walled profiles of very soft materials, because no classical mechanical forces act on the workpiece, as is the case with conventional machining. The principle is the thermoelectric removal of the workpiece material into the shape of the used tool electrode in the presence of the working medium-dielectric liquid (most often kerosene). EDM makes it possible to machine all at least minimally electrically conductive materials, regardless of their mechanical or physical properties. Technologies fully adapted for the production of micro-parts include unconventional technologies of electrical discharge die-sinking machining (EDM) 2, 3. Due to the growing demands for product miniaturization in many areas of industry, it is necessary to constantly increase the demands on individual production technologies so that these parts can be produced with the required precision and quality. Micromachining is generally characterized as the production of parts with dimensions less than 1 mm 1. Micro-EDM technology has been found to be suitable for the production of miniaturized slits. Using multi-criteria optimization, the optimal setting of the machine parameters for the production of a given slit was determined, which is Pulse current = 2.1 A, Pulse on time = 40 µs and Voltage = 238.8 V.

A design of experiment Box and Behnken Response Surface Design was performed for a total of 15 rounds, monitoring the effect of machine setting parameters (Pulse current, Pulse on time and Voltage) on responses in the form of Erosion rate, corner radius, slot length and width.

The same copper foil was used as a tool, which represents an advance in the production of micro-parts.The use of the same semi-product for the production of the slit as well as the tool itself has not yet been presented in any similar study. For this reason, this study was performed, which focused on the production of a precise slot measuring 5000 × 170 µm in a copper foil with a thickness of 125 µm. These contain miniaturized parts, which are, however, necessary for their proper functioning. One of the industrial products is also optical devices used for testing cars. However, the required quality and accuracy must be maintained, which can be achieved with micro-EDM. The trend of miniaturization of industrial products is obvious. It allows machining of at least at least electrically conductive materials. Electrical discharge machining (EDM) is an unconventional machining technology.
