AN EXPERIMENTAL STUDY ON ROUNDNESS ERROR IN WIRE EDM FOR FERRO MATERIALS

Abstract

 Heavy-duty alloy alloys such as SS316, EN24, and H13 play a major part in the current 
industrial phenomena for the manufacturing of dies and moulds. There is a strong preference for Wire 
EDM use for alloy material machining because of the cost savings and reduced tool wear that it 
provides. Additionally, precise machining of cavities, inserts, holes and radius is a benefit of Wire EDM 
because of its high level of precision. The roundness of the item is critical in all of these machining 
scenarios. Pulse deviation has been automatically adjusted in Wire EDMs, and the number of cutting 
repeatability has been raised depending on product quality. The roundness of inserts is critical to their 
assembly. By adjusting the distance between the nozzle and cutting head, the roundness error may be 
increased or decreased. An insert-based investigation with constant thickness and a constant radius 
yielded excellent results with several radiuses in one profile.
