Investigation on CWEDT process limitations and irregularity occurance

Production of small cylindrical parts from electrical conductive materials, which are difficult to machine by a conventional cutting method can be achieved with Cylindrical Wire Electrical Discharge Turning process (CWEDT). The main application disadvantage of CWEDT process is amount of time necessary for part production in comparison to conventional machining. Therefore large majority of the CWEDT process research deals with identifying the highest process factor levels to increase material removal rate (MRR). Experimental procedure and observations for determining research solution field is shown. The process parameters levels are determined which value change can improve stability of process. Early detection of process irregularity is done by electric pulse monitoring. Conclusion has been made about role of machine servo feed on process stability, together with influence of process parameters on irregularity phenomena.
