This article describes the findings of an experimental investigation aimed at determining the impact of input parameters on the electrode wear rate (EWR) in powder-mixed electrical discharge machining (PMEDM) of cylindrical-shaped components made of 90CrSi tool steel, using graphite electrodes. The study examined the impact of several input process factors, such as the powder concentrate Cp, pulse time Ton, pulse off time Toff, servo current IP, and servo voltage SV, on the EWR. Furthermore, suggested input settings that yield the smallest EWR have been proposed.

摘要

This article describes the findings of an experimental investigation aimed at determining the impact of input parameters on the electrode wear rate (EWR) in powder-mixed electrical discharge machining (PMEDM) of cylindrical-shaped components made of 90CrSi tool steel, using graphite electrodes. The study examined the impact of several input process factors, such as the powder concentrate Cp, pulse time Ton, pulse off time Toff, servo current IP, and servo voltage SV, on the EWR. Furthermore, suggested input settings that yield the smallest EWR have been proposed.
