Research on the characteristics of debris particles in short electric arc milling of GH4169
As a product of Electrical Discharge Machining(EDM),debris particles can not only reflect the state of the discharge gap but also help to understand the mechanism of material removal.Therefore,debris particles have always been a research hotspot in the field of EDM.As a novel,high-efficiency EDM method,Short Electric Arc Milling(SEAM)has problems such as poor chip removal and frequent short cir cuits.Based on the above problems,debris particles were used as the research object.Firstly,the microscopic morphological characteristics of the debris particles were studied,and the effects of different workpiece polarity,e-lectrode materials,voltage,duty cycle and frequency on particle size distribution of the debris particles were discussed from the perspective of discharge energy.The influence of particle size distribution of the debris particles on the processing quality was fur-ther summarized.Guidance for revealing the material erosion mechanism,improving the gap chip removal performance and enhan-cing the stability of the machining process was provided.
