Original abstract

The unconventional wire electric discharge machining technology (WEDM) is widely used in many industries, which is why thereis a permanent emphasis on increasing the quality of such machined surface. The aim of this studywas to carry out a design of experiment (DoE) to reduce the surface qualityparameterPq. During the 33-round experiment, the input factors – machine setting parameters, such as gap voltage, pulse on time, pulse off time, wire speed, and dischargecurrent, werechanged. Subsequently, Pq – rootmean square deviation of the primary profile and Pa – arithmetic average of the primary profile were evaluated on the machined surfaces of pure aluminium. By using DoE, the setting of the machine’ sparameters was designed in order to achieve the highest possible surface quality.

Nekonvenční technologie elektroerozivního drátového řezání (WEDM) je široce využívána v mnoha odvětvích průmyslu, proto je neustále kladen důraz na zvyšování jakosti takto obrobeného povrchu. Cílem této studie bylo provedení plánovaného experimentu (DoE) za účelem snížení parametru jakosti povrchu Pq. V průběhu 33 kolového experimentu byly měněny vstupní faktory – parametry nastavení stroje, jako jsou gap voltage, pulse on time, pulse off time, wire speed and discharge current. Následně byly na obrobených površích z čistého hliníku vyhodnoceny parametry Pq – root mean square deviation of the primary profile a Pa – arithmetic average of the primary profile. Použitím DoE bylo navrženo nastavení parametrů stroje pro dosažení co možná nejvyšší jakosti povrchu.
